Abstract

One-dimensional perovskite nanowires (PNWs) materials have attracted attention in integrated photonics and photovoltaic device due to their unique optoelectronic properties, such as large-scale optoelectronic integration, high-density data storage and low defect states density. However, many fundamental questions concerning structure and performance, especially the light-induced performance changes in the PNWs solar cells are still unclear. In this work, a continuous light irradiation (0-90 mins) was carried out to study the device performance, structure changes and electrochemical dynamics property in MAPbI3-xClx PNWs devices. We observed that the device efficiency first increases and then decreases with the prolongation of light illumination time. When the illumination reaches to 5 mins, the device exhibits a highest PCE of 15.06%, which possibly due to structural change caused by the ion migration and accumulation. The possible mechanism was elaborated for the first time..
