基于相异质结的高效无机钙钛矿太阳能电池的性能研究
Research on the performance of inorganic perovskite solar cells based on phase heterojunction
摘要
Abstract
Inorganic perovskites have attracted a lot of attention due to their excellent optical and thermal stability,but high-efficiency inorganic perovskite solar cells often need to be modified with organic materials,which limits the improvement of device stability to a certain extent.In order to effectively solve this problem,a phase heterojunction(PHJ)strategy was proposed to modify interface inorganic perovskite solar cells(IPSCs)with high efficiency.The PHJ was constructed between the upper interface of the optical absorption layer and the hole transport layer of the inorganic perovskite by spinning methanol solution and evaporating cesium iodide(CsI).Effective management of interface defects is achieved,non-radiative recombination is reduced,and carrier driving and separation are facilitated.Finally,N-I-P IPSCs based on the PHJ strategy achieved a photoelectric conversion efficiency of 20.56%,much higher than the 18.03%of the reference group,and retained 86.14%of their initial efficiency when placed in 65℃nitrogen(N2)atmosphere for 1000 h.关键词
