Research group developed a highly efficient solar cells

From Japan, the United States and the Czech Republic and other countries, a research scientists have developed a new group of amorphous silicon solar cell, the photoelectric conversion efficiency of solar cells may be higher than current products. According to media reports, a new type of solar cells using electric field effect of the structure, its specific composition is: electrodes - thin-film amorphous silicon - electrode - transparent insulators - conductive film. Its principle is: through the insulator and amorphous silicon thin film applied voltage to reduce electronic resistance movement in order to improve the efficiency of photoelectric conversion.

At present, the production and use of photovoltaic solar cell conversion efficiency of about 17%. Test showed that the new structure of the photovoltaic solar cell conversion efficiency than the existing products to increase 35% to 50%.
