The researchers developed a conversion efficiency of 6.7% of the programs address the type of small molecule solar batteris, comparable to the best of its performance polymer solar batteris, and may achieve better stability of large-scale production, new results published in the 11 January online issue of “Nature – materials” journal.
Organic bulk heterojunction solar batteris made from organic semiconductor compounds, can convert sunlight into electricity. Through the process of printing and other programs to address the possibility of storage of organic semiconductors, these materials have the potential to be applied to flexible large-area photovoltaic devices mass production. Today, the most efficient organic bulk heterojunction solar batteris are made from semiconductor polymers. The reasons for the synthesis process, and small molecule solar batteris, semiconductor mass production of polymer structure and device performance will be on an even greater difference between the bulk.
Through careful design, Guillermo Bazan and colleagues developed a highly efficient heterojunction can be used for solar battery mass production of small molecule semiconductors, the performance of these devices is close to the best polymer solar batteries.
