摘要

The performance of hybrid organometallic perovskite solar cell in the past two years has proven surpassed the conventional dye sensitized solar cell Despite of the rapid progress there are several drawbacks such as instability to air and moisture and the use of toxic lead in the perovskite absorber layer Sn based perovskite exhibits an absorption edge up to 1000 nm However the performance of Sn based perovskite of CH3NH3SnI3 is not as good as lead based perovskite of CH3NH3PbI3 The primary reason is the more severe oxidation of the CH3NH3SnI3 In this research we use chloride inclusion during formation of perovskite in Pb based perovskite to improve crystallinity of CH3NH3PbI3 Herein we perform material and optical characterization of crystal CH3NH3SnI3 with chloride inclusion to study the implication of the Cl on the properties of Sn based perovskite using one-step solution process by varying the precursor ratio annealing temperature annealing time and mixed Pb:Sn ratio In this study we present the observation of chlorine inclusion to the crystal perovskite by X ray Photo spectroscopy and X Ray Diffraction film morphology by using Scanning Electron Spectroscopy as well as their implication to material properties by using UV-Vis Spectroscopy photoluminescence and devices performances
