Carrier Transport Layer Addives (93)

Additives in the carrier transport layer are crucial for improving charge extraction and transport in perovskite solar cell materials. For instance, tin oxide (SnOx) can be applied via atomic layer deposition to create a robust electron transport layer. These additives optimize the interface between the active and transport layers, reduce non-radiative recombination, and minimize energy losses, thereby enhancing the overall photoelectric conversion efficiency of perovskite solar cells.
