Deposition methods have been used extensively to achieve high-quality, semi-transparent solar cells. Here, we have studied semi-transparent electrodes based on WO3 and Ag, to boost the PCE in semi-transparent formamidinium lead bromide (FAPbBr3) solar cells. A screening upon the mixed halide perovskite, from pure bromide to pure iodide has been made, demonstrating that the PCE increase with the semi-transparent electrode compare to the conventional semi-transparent Au. This work demonstrates the potential use of semi-transparent electrode to improve the light harvesting of the perovskite layer, by using optical methods to compensate chemical limitation, paving the way for application in building integration.
