Abstract

The architecture of perovskite solar cells (PSCs) and the interfaces between charge transport layers and the perovskite layer are crucial to performance. These layers impact the morphology of the perovskite layer and the processes of charge extraction and recombination. This study investigates performance enhancement in PSCs by incorporating PEDOT: PSS and PTAA as hole transport layer (HTL). Various surface treatments were used to improve PTAA’s wettability, significantly enhancing layer adhesion and overall cell efficiency. Our findings suggest that optimizing HTLs and surface treatments can lead to more efficient and stable PSCs.
