Abstract

Purpose

The aim of this paper is to present results of investigations carried out on the front electrode of solar cells. Nowadays, most worldwide solar cell production is dominated by monocrystalline and polycrystalline silicon as a base material. In such cells, the electrical carriers are collected by the system of metallic paths fabricated on a silicon surface. One possible way to increase cell efficiency and reduce the production costs of solar modules is to replace the expensive silver by cheaper copper in front metallic electrodes.

Design/methodology/approach

The paper presents results of investigations performed on the front electrode of the solar cell. The investigations were focused on the modification of typical screen printing fabrication of the thin electrical finger paths of the front solar cell electrode. The resulting contacts were characterized morphologically (the dimensions and geometry of the front contacts) by scanning electron microscopy. The composition of finger path covered with copper was analyzed using energy-dispersive X-ray spectroscopy and X-ray photoelectron spectroscopy techniques.

Findings

In this work, the front electrodes were screen printed with the use of conventional silver-paste on a p-type Cz–Si-textured wafer with a n+ emitter and with an antireflection coating. After that, the fired front electrode was electroless coated with copper. The electroless copper deposition was performed in two stages. First, the surface of the photovoltaic cell was dipped in an aqueous solution of CuSO4 and then dried in air at room temperature. When the surface dried, the cell was immersed in hydrogen fluoride solution (5 per cent) for 1 s followed by rinsing in deionization water.

Originality/value

The experiments confirmed the potential application of copper as an additional layer of the solar cell front metal electrode. On the one hand, this process is very simple and, on the other, the authors demonstrate a problem with the mechanical stability of the covered paths leading to electrode delamination.

Abstract

Purpose

The paper aims to show application of the electrochemically deposited coatings for thickening of the screen printed electric paths potentially applied in photovoltaic cells.

Design/methodology/approach

The electric paths were screen printed with the use of silver-based paste. The paths were thickened by electrodeposition of thin copper layer in potentiostatic regime from surfactant-free plating bath. The morphology and surface quality of the paths were studied by imaging with scanning electron microscopy.

Findings

The electric paths can be thickened successfully, but quality for the screen printed substrate determines quality of deposited layer. The EDX analysis confirmed that the deposited copper layer covered uniformly the printed paths.

Research limitations/implications

The adhesion of the copper-covered path to the silicon wafer surface depends on adhesion of the original screen printed path.

Originality/value

This paper confirms that electrodeposited copper can be applied for screen printed silver paths thickening in a controllable way.

Abstract

Purpose

With the aim of developing a better understanding of why some consumers still excuse corporate brands that engage in transgressions, this study tests whether extrinsically religious people tolerate corporate brands more than intrinsically religious individuals at different transgression levels (severe and mild) and punish them less than the latter.

Design/methodology/approach

This study adopts a 2 × 2 experimental design to manipulate corporate brand transgression levels (mild vs severe) and religiosity orientations (intrinsically religious vs extrinsically religious) on a convenience sample of 134 subjects who live in Turkey, a country where Islam shapes religious context. It uses a scenario technique and projective approach.

Findings

While the main effect of corporate brand transgression on punishing behaviour does not appear in the analysis, religiosity’s main effect on the latter does. Unexpectedly, extrinsically religious consumers punish corporate brand transgressors more than their intrinsically religious counterparts regardless of the transgression severity levels.

Research limitation/implications

Although the study does not refer to any religion in particular, countries predominated by religions other than Islam may yield different consumer reactions. Future studies should focus on transgressions in such different settings.

Practical implications

Corporate brand transgressors should immediately take up good causes to attract the attention of intrinsically religious consumers. Otherwise, for the sake of showing off, extrinsically religious people may punish the transgressor for its intentional mistakes, which may harm corporate brand associations.

Originality/value

This study examines the link between religiosity and corporate branding. Unique in this way, it introduces religiosity as a valid contributor that can explain why some consumers do not punish corporate brand transgressors, especially in countries like Turkey where religiosity is intertwined with the developments in the liberal economy which led to the emergence of a new middle class.

Abstract

Purpose

The purpose of this paper is to examine the relationship between management education, the performance of German engineering enterprises and the strategic knowledge status of the executives running those enterprises.

Design/methodology/approach

The paper is based upon the results of an online/posted self‐administered questionnaire conducted within Germany, augmented by micro case studies.

Findings

Findings suggest that the curricula in German Engineering Faculties fail to fully embrace business and management studies, in particular strategic management which has virtually no presence. Engineers dominate senior management positions within the German machinery and equipment sector yet they display limited knowledge of strategic management tools. There is also evidence that links performance with the application of management knowledge.

Research limitations/implications

The study is limited to senior executives within German SMEs from the machinery and equipment sector. It is likely that the findings would be applicable throughout the German engineering industry; however, generalisability to other countries may be limited. Only a single year's performance (2007) was considered and this is also a limitation of the study. This was mitigated by a request that anomalies be noted, such as extraordinary write offs or a windfall profit, within the year in question, this was then taken into account during the analysis.

Practical implications

Based on the findings it is suggested that German faculties of engineering should enhance and expand management education, particularly strategic management, thus enhancing future performance potential within German SMEs.

Originality/value

This paper examines the level of management education attained by senior engineering executives with a key economic industrial sector in Germany, as such it is one of few such studies which investigates the link between management education and performance.

Abstract

Purpose

This paper aims to explore to what extent senior executives, particularly within the German machinery and equipment small- and medium-sized enterprises (SMEs), gather and apply knowledge pertaining strategic management (SM) tools. Furthermore, the study aims to provide research evidence as to whether or not the companies derive any performance enhancing benefit from the appliance of said with the knowledge.

Design/methodology/approach

The research relied on a self-administered questionnaire mailed or posted to the entire population of about 6,000 enterprises. The resulting data were analyzed with the statistical package for social science (SPSS) statistical software package.

Findings

Executives within the sector, especially those with a predominantly engineering background, lack both knowledge and understanding of SM in general and strategic tool-kits in particular. Interestingly, educational background, in association with toolkit usage, appears to enhance organizational performance.

Research limitations/implications

The German educational system, in conjunction with the associated professional development infrastructures, may impact the generalizability of the research findings.

Practical implications

The results from this study can be used for lobbying policy-makers and shapers, e.g. government, higher education, industry and professional bodies, to improve and expand engineering management education so that practitioners have the knowledge of and competency in SM.

Originality/value

The study provides an insight look of how executives in one of Germany’s most successful industries deal with the knowledge and application of SM tools and their impact on performance. Extant research has not dealt with Germany or this sector in relation to the appliance of strategy-related knowledge and performance.

Entrepreneurship, venture creation and business management.

Abstract

Subject area

Entrepreneurship, venture creation and business management.

Study level/applicability

The case is suitable for analysis in an undergraduates program specializing in entrepreneurship, business and management. The case could also be discussed in an executive development program on business ventures/business strategy/business management.

Case overview

Since its inception in 1981, Abdul Rahim Al Fahim, CEO Paris Gallery decided that Paris Gallery would foray into French perfumes. At that time, he would have never thought that such a move would ever make him more than a shopkeeper. Now in 2016, Mr Abdul Rahim Al-Fahim has much to be pleased about the success that his organization Paris Gallery (Luxury stores in Dubai) has been able to achieve. He has been twice named as the Arab World’s most powerful retail sector entrepreneur. Certainly, it was his good fortune to be based in the great city, and his business venture has paralleled the exponential success of Dubai. As the concept of grand malls developed and flourished in UAE, Paris Gallery stores emerged and also prospered. Currently, Paris Gallery has 80 stores in the finest locations of the Middle East. This encourages family business owners in UAE to have ambitions for success and growth of their enterprises. This is especially true in a developing region that has rarely hosted such a high-end homegrown success story as Paris Gallery. The study of strategic positioning of Paris Gallery with a workforce of 4,000 employees and representing more than 550 international brands today shall help us in weighing the options of how businesses should proceed strategically.

Expected learning outcomes

The following insights could be elucidated by the case: familiarizing students with the business challenges in the retail industry in emerging markets such as the United Arab Emirates, and exploring future strategy options from the business growth perspective.

Abstract

At three o'clock in the morning on September 10, 2001, Thierry Hautillac, a risk arbitrageur, learns of the final agreement between Pinault-Printemps-Redoute SA (“PPR”) and LVMH Moët Hennessy Louis Vuitton SA (“LVMH”). After a contest for control of Gucci lasting over two years, PPR has emerged as the winner. PPR and LVMH have agreed for PPR to buy about half of LVMH's stock in Gucci for $94 per share, for Gucci to pay an extraordinary dividend of $7 per share, and for PPR to give a two and a half year put option with a strike price of $101.50 to the public shareholders in Gucci. The primary task for the student in this case is to recommend a course of action for Hautillac: should he sell his 2% holding of Gucci shares when the market opens, continue to hold his shares, or buy more shares? The student must estimate the risky arbitrage returns from each of these choices. As a basis for this decision, the student must value the terms of payment and consider what the Gucci stock price will do upon the market's open. The student must determine the intrinsic value of Gucci using a DCF model as well as information on peer firms and transactions. The student must consider potential synergies between Gucci and PPR and between Gucci and LVMH. The student must assess the likelihood of a higher bid, using analysis of price changes at earlier events in the contest for clues.
