Achieving high-efficiency perovskite-based solar cells through engineering hole-transport layer

A comprehensive review on the advancements and challenges in perovskite solar cell technology

“…The rapid movement of charge carriers (electrons and holes) to the electrodes minimizes recombination losses, thereby enhancing the overall efficiency of the solar cell. 17 In addition, this efficient carrier movement reduces internal resistive losses, ensuring that less energy is lost as heat and maintaining high efficiency during operation. This high carrier mobility is also beneficial under low-light conditions.…”
