scientists have developed Low cost solar cells that are cheaper and more efficient

A preview of researchers from the Chinese Academy of Sciences (CAS) and the University of Linköping has paved the way for high cell efficiency, and profitable site of the polymer are much more reliable compared to what we have today. The research aims to focus the development of polymer solar cells without having to use the expensive and unstable fullerene, an allotrope of carbon.

Previously, scientists relied on fullerenes high efficiency ‘when added to the polymer solar cells to divide the charge carriers, but nevertheless had a significant problem with the use of fullerene – Found to obtain highly unstable, the formation of large crystals high temperatures, and this behavior was disturbing.

Currently, a team of chemists from the CAS, led by Professor Jianhui Hou, has achieved a revolutionary cell polymer contains no fullerenes. This is a world record, obtained by developing a new combination of a small molecule called ITIC with the polymer called PBDB-T. This combination helps transform the sun’s energy with an efficiency of 11%, an unprecedented value so far for solar cells without fullerenes.

Gao Feng and his colleagues Olle Ingan and Deping Qian at Linköping University have studied the spectroscopy loss photovoltage (Voc), a component of high importance for solar cells. They have even suggested new ideas that could improve the performance and efficiency of the device. Feng said that the high efficiency of even thermally stable solar cells could produce without having to go with fullerene. They are planning to commercialize this innovation soon after your document is printed.
His research publish in the latest issue of the journal Advanced Materials.
