dc.description.abstractWe report the design of a nanophotonic metal-oxide front contact aimed at perovskite solar cells (PSCs) to enhance optoelectronic properties and device stability in the presence of ultraviolet (UV) light. High-quality Cr-doped ZnO film was prepared by industrially feasible magnetron sputter deposition for the electron transport layer of PSCs. As a means, the influence of the Cr content on the film and device was systematically determined. In-depth device optics and electrical effects were studied using advanced three-dimensional opto-electrical multiphysics rigorous simulations, optimizing the front contact for realizing high performance. The numerical simulation was validated by fabricating PSCs optimized to reach high performance, energy conversion efficiency (ECE) = 17.3%, open-circuit voltage (VOC) = 1.08 V, short-circuit current density (JSC) = 21.1 mA cm?2, and fill-factor (FF) = 76%. Finally, a realistic front contact of nanophotonic architecture was proposed while improving broadband light absorption of the solar spectrum and light harvesting, resulting in enhanced quantum efficiency (QE). The nanophotonic PSC enables JSC improvement by ?17% while reducing the reflection by 12%, resulting in an estimated conversion efficiency over 23%. It is further demonstrated how the PSCs� UV-stability can be improved without considerably sacrificing optoelectronic performances. Particulars of nanophotonic designed ZnO:Cr front contact, PSCs device, and fabrication process are described.
