Solution-processed BiI3 solar cells

We present a proof-of-concept solid state solar cell with an efficiency of 1.0 % using solution-processed BiI3 absorber layer. Spin-coated BiI3 thin films show stability in air for over one month. The films were integrated into an all-inorganic photovoltaic device with a transition-metal oxide hole transport layer. Thermal annealing BiL· films at 100 °C in… CONTINUE READING
