| Popis: | 25th European Photovoltaic Solar Energy Conference and Exhibition / 5th World Conference on Photovoltaic Energy Conversion, 6-10 September 2010, Valencia, Spain; 3403-3405 Development of lightweight and flexible solar cells using roll-to-roll manufacturing and monolithic interconnection technology can lead to a significant reduction in the manufacturing cost of solar modules. We have been conducting research and development work for improving the efficiency of flexible CIGS solar cells and implementing monolithically interconnected solar modules. A vacuum evaporation process for the growth of high quality CIGS absorber layers at sufficiently low temperature of about 450°C and a method of Na incorporation for improving the electronic properties have been developed. Flexible solar cells with a record efficiency of 17.6% and monolithically interconnected mini-modules with 12.1% efficiency have been realized. Analyses of photovoltaic properties suggest that efficiencies above 18% are achievable. |
