Abstract Two facts are in the focal point of this thesis: First that the PV industry is one of the most prospering ones worldwide with a growing rate of around 40% every year, second that for reaching the Kyoto- as well as the EU 2020 targets also the industry will be strongly involved. PV-power plants could be one possibility in lowering the CO2 output by producing the needed electricity; supplying optical parts could be the gate to the PV industry for Swarovski as the company is the world leader in producing cut crystal. These optical parts are needed for the concentrating Photovoltaic (CPV), which have a huge market potential as the development of these systems is just at the beginning. At the moment no kind of CPV can be favoured, new developments for whole CPV systems or of optical parts of them are possibilities for Swarovski. Because of the low feed-in tariffs in Austria, the non-supporting of PV in Tirol and the high long- term internal interests of the company itself, it is not possible to run a PV-power plant economically. There are huge differences between fixed or moving systems with advantages to optimal inclined fixed and 1-axis systems, but all of them would have negative financial results. Other reasons like a positive “green” image or being an outrider of new technologies have to be found if a PV-power plant should be erected at the company area.

Swarovski & Co is a worldwide operating company with more than 20,000 employees in over 120 countries. 2006 reaches the turnover €2.37 billion. Beside the main brand “Swarovski” the “Swarovski group” unites the brands Tyrolit (sawing-, drilling-, grinding tools), Swareflex (glass reflectors for roads), Signity (natural and synthetic gemstones) and Swarovski Optics (binoculars, scopes). Swarovski itself is the world leader in precision cut crystal. Crystal is the short form for lead crystal, a high brilliant faceted variety of glass. Swarovski has two major divisions: The first is producing precision-cut crystal components, catering to a wide range of design-driven industries in the fashion, lighting and interior business. The second is using these elements to create finished crystal products like jewellery (figure 1, right picture), fashion accessories, and home décor objects, which are sold through the worldwide network of more than 1150 Swarovski stores. The main production plant is situated in Wattens / Tirol with more than 6700 employees by the end of 2007. The main industrial work is done in three shifts, 24 hours and 7 days a week. Figure 1: Swarovski crystal swan and Swarovski crystal earrings and pendant Crystal melting and cutting is a very energy consuming work, using a huge amount of oil, gas and electricity. The melting process for example needs temperatures of ~1400°C and lasts about 24 hours. The energy consumption to produce glass is in average 1.50 kWh/kg or 12-20% of the total production costs (Fröhler 2005, page 1301). Dr. Arno Recheis 5 MSc Program Renewable Energy in Central & Eastern Europe 3.2. Terms of this thesis Although Swarovski has own hydropower plants (chapter 4) producing about 36% of the needed electricity the company is mostly depending on fossil energy sources. Together with the company the energy consumption is growing in average 10% each year increasing this dependence. Of course no company (region or nation) wants this dependence particularly when looking on the Russian gas crisis in 2006 or on the uncertain world oil market. Renewable Energies sound to be the golden key out of this dependence. Beside this important fact they can even be more. The PV industry for example is one of the fastest growing branches (+25-50% every year) worldwide. So there is also the question if a company like Swarovski is able to get into this prospering market. This thesis deals by focusing on Photovoltaic as a possible new business field with two different roles: an active or a passive one. • The concentrating Photovoltaic (CPV) uses optical parts (lenses, mirrors) which are often made of glass. This can be a chance for the company in future. Looking on the core- competences and based on a SWOT analysis the possibilities of this active role for D.
