The Tin-based perovskite is an encouraging material in the development of non-toxic solar cell application, but its performance is limited by the poor chemical stability against oxygen and moisture. Therefore, tin-based perovskite solar cells are mostly fabricated in inverted planar device structures and the selection of underlying hole transport material plays a significant role in device stability. In this work, we report the comparison study between a metal oxide, nickel oxide, and polymeric poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT: PSS) as a hole transport layer on device efficiency and stability of tin-based PSC. We obtained comparatively higher power conversion efficiency (PCE) with NiO x than others, however, the solar cell with PEDOT: PSS is more stable rather than NiO x for the duration of 900 hrs in a nitrogen ambient, without encapsulation.
