摘要: This work describes the role of relative humidity (R.H.) on performance degradation methyl-ammonium lead-iodide (CH3NH3PbI3) based hole transport material (HTM) free hetero-junction perovskite solar cell. It has been observed that power conversion efficiency (η) cells decreases from 4.52% to 1.28% with increases in R.H. <40% 75%. A semi-analytical optoelectronic model is further developed explore effect limiting parameters, i.e. absorption coefficient, diffusion length. The shunt resistance whereas space charge region width and series respect increase carrier losses through recombination, spatial relaxation thermalization are also analysed found 76% at <40%R.H 84% 75%R.H.
