SOLAR CELLS


General Information

Research conducted by Panasonic over many years on solar cells and the application of this new technology culminated in 1984 with the successful development of the world’s first thin-film solar cell using compound semiconductors. The company named these cells Sunceram II. The Sunceram II cells have good weatherproof properties and high spectral sensitivity characteristics over a wide wavelength range. Furthermore, since the entire film-forming process involves only s ....etc

Crystalline-Silicon Solar Cells for the 21st Century


ABSTRACT
The worldwide market share for crystalline-silicon solar cells has
increased steadily in the last 10 years. In 1998, about 87% of the
photovoltaic modules shipped worldwide are based on crystalline
silicon. This dominance will likely continue into at least the first few
years of the 21st century. The long-term growth of crystalline-silicon
solar cells will depend on the development of low-cost ....etc
