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