电子传输层表界面工程对钙钛矿薄膜结晶行为的影响
Influence of Electron Transport Layer Interface Engineering on Crystallization Behavior of Perovskite Films
摘要
Abstract
The photovoltaic performance and stability of perovskite solar cells are highly dependent on the structure and properties of the perovskite active layer.By regulating the electron transport layer/perovskite ac-tive layer(ETL/PVK)heterojunction interface,the nucleation thermodynamics and kinetics,as well as crys-tallization behavior,grain orientation,and microstructure of perovskite films are influenced.This review sys-tematically examines how the surface properties of ETL(including surface energy,wettability,functional groups,and lattice matching)guide the evolution of perovskite from solution precursors to solid phase accord-ing to interfacial physicochemistry.The three main mechanisms of the ETL regulating perovskite crystalliza-tion are discussed:Controlling the nucleation barrier through interface energy to affect nucleation density;Guiding crystal growth direction through surface functional group;Inducing preferred orientation formation through interface coupling effect.Further analysis is conducted on the impact of the resulting crystallographic features(grain size,orientation,grain boundary properties)on charge transport,ion migration,and device stability.This review aims to deepen the understanding of the scientific essence of ETL/PVK interface and provide a theoretical support for the preparation of high-quality perovskite films.关键词
