Solar cell mystery solved, expected to greatly increase efficiency

(Phys.org)-For the past 17 years, spiro-OMeTAD, has been keeping a secret. Despite intense research efforts, its performance as the most commonly used hole-transporting material in perovskite and dye-sensitized solar cells has remained stagnant, creating a major bottleneck for improving solar cell efficiency. Thinking that the material has given all it has to offer, many researchers have begun investigating alternative materials to replace spiro-OMeTAD in future solar cells.

Nano-engineering enhances charge transport, promises more efficient future solar cells

(Phys.org) -Solar cells based on semiconducting composite plastics and carbon nanotubes is one of the most promising novel technology for producing inexpensive printed solar cells. Physicists at Umeå University have discovered that one can reduce the number of carbon nanotubes in the device by more than 100 times while maintaining exceptional ability to transport charges. This is achieved thanks to clever nano-engineering of the active layer inside the device. Their results are published as front page news in the journal Nanoscale.
