Abstract
AbstractOrganic lead halide perovskites are regarded as qualified candidates for the photoactive layers of semitransparent solar cells. The critical aspect of boosting the performance of semitransparent perovskite solar cells (PSCs) to a higher level lies in preparing perovskite films with both excellent photoelectric properties and high transmittance. Herein, it is realized that, through theoretical analysis, perovskite materials with bandgap of 2.00–2.30 eV are suitable for the preparation of semitransparent PSCs that can simultaneously achieve low thermal‐energy loss, allow transmission of light for high photopic response, and provide acceptable transmittance for photovoltaic greenhouses. Then the study aims at improving the crystallinity and morphology of wide‐bandgap perovskite films by using additive engineering. As such, PSCs with absorber bandgaps of 2.02, 2.16, and 2.32 eV deliver maximum power‐conversion efficiencies of 12.08%, 9.17%, and 8.42%, respectively. Then the corresponding semitransparent PSCs are crafted with average transmittance of light detectable by the human eye of 9.41%, 23.26%, and 43.47%, respectively. Furthermore, the crop growth factors are predicted to be 21.25%, 29.48%, and 37.07%, respectively. This work gives full play to bandgap modulation in the fabrication of semitransparent PSCs, which will broaden the application of semitransparent solar cells in the field of building integrated photovoltaics.
