钙钛矿太阳能电池电子传输层与界面调控的研究进展
Recent Advances in Electron Transport Layers and Interface Engineering for Perovskite Solar Cells
摘要
Abstract
Perovskite solar cells(PSCs)have achieved remarkable progress in the field of solar photovoltaics in recent years due to their excellent power conversion efficiency(PCE)and low production cost,making them one of the current research hotspots.However,the PCE of PSCs has yet to reach its theoretical limit,and their insufficient long-term operational stability remains a key bottleneck restricting large-scale application.As a critical functional layer in PSCs,the electron transport layer(ETL)plays a vital role in electron extraction and transport,with its material properties,interface quality,and structural design directly affecting the overall device performance.To address these challenges,multidimensional optimization strategies have been proposed in recent years,focusing on materials innovation,interface engineering,and structural design.These strategies synergistically improve the PCE and environmental stability of PSCs through the development of novel high-performance ETL materials,interface engineering for defect passivation and energy level alignment,and microstructural regulation to optimize electron transport pathways.This review systematically summarizes the recent research progress on ETL materials,with emphasis on their properties,development trends,and integration with perovskite materials.In addition,it analyzes the challenges associated with optimizing the ETL/perovskite interface.By summarizing existing research strategies,this review aims to provide a comprehensive reference for the design and development of high-efficiency and stable PSCs.关键词
