A new study challenges the conventional wisdom that doping Spiro-OMeTAD is essential for high-efficiency perovskite solar cells, particularly in indoor applications. Researchers explored the performance of lead halide perovskite (LHP)-based photovoltaic devices that utilize Spiro-OMeTAD as the hole-transport material, comparing doped variants with those left undoped.
Surprisingly, while th
