Perovskite based on methylammonium lead iodide (MAPbI3) have attracted great attention for the past few years as promising materials for both photovoltaics and photodetector technologies. In this work, we report on the solution-processed of MAPbI3 via spin-coating method prepared at high humidity condition. The compact film of MAPbI3 with grain size of 200 nm and high crystallinity was obtained. Based on the current density –voltage (J-V) measurement, relatively high power conversion efficiency of 11.3% of PSCs can be achieved when processing the MAPbI3 film at high humidity. In addition, the calculated detectivity and responsivity of perovskite photodetector can reached up to 2 A W-1 and 2 x 1012 Jones at wavelength of 500 nm with rapid response time of 2 ms.This finding shows that MAPbI3 processed at high humidity can achieve both high photovoltaic and photodetector performance.
