Inverted perovskite solar cell with antimony-doped tin oxides achieves 25.7% efficiency

Researchers in Singapore have built an inverted perovskite PV device with a p-type antimony-doped tin oxides (ATOx) interlayer that reportedly reduces the efficiency disparity between small and large-area perovskite cells. According to their findings, ATOx may easily replace commonly used nickel oxides (NiOx) as a hole transport material. An international research group led by the National University of Singapore (NSU) has fabricated an inverted perovskite solar cell by placing p-type antimony-doped tin oxides (ATOx) combined with methyl-substituted carbazole (Me-4PACz) as an interlayer between ...
