| Popis: | 28th European Photovoltaic Solar Energy Conference and Exhibition; 2236-2238 The world’s highest level of power conversion efficiency up to 9.0% was attained in polymer photovoltaic modules. This value surpasses our previous world records of 6.8% and 8.2% that are listed in the latest Solar Cell Efficiency Tables ver.41 and ver.42 [1]. The sizes of previous and current record modules are 396cm2 and 25cm2, respectively. For these achievements, three kinds of elementary technologies were developed; (1) meniscus coating/patterning technology, (2) device optimizing technology and (3) original materials for the cells and the modules. By the meniscus method, uniform thin layers of nano-scaled thickness are formed with thickness variation less than 3%. Accurate patterning of the striped cell is also performed using plural split coating applicators, so that highly integrated modules with the active/total area ratio up to 94% were fabricated without any scribing process. By device simulation technology, various design parameters for modules were numerically optimized. Cell efficiency up to 10.3% (1cm2) was obtained by our original donor polymer. We have also developed some prototypes for electronics integrated photovoltaic (EIPV) mounted with our OPV (Organic photovoltaics), which can be driven by the power generation under indoor lightings. |
