A Theoretical Investigation of Transport Layer‐Free Homojunction Perovskite Solar Cells via a Detailed Photoelectric Simulation (Adv. Energy Mater. 12/2023)

Perovskite Solar Cells In article number 2203366, Zhenhai Yang, Xiaofeng Li, and co-workers clarify the design principles and working mechanisms of transport layer-free homojunction perovskite solar cells through optical and electrical simulation. Moreover, the effects of the internal physical behaviors including ion migration and photon recycling on device performance are also demonstrated, providing valuable guidance for fabricating high efficiency perovskite solar cells.
