摘要
Organic solar cells(OSCs) continuously attract much attention due to their potentials as the low-cost and lightweight sources of renewable energy,and the power conversion efficiency(PCE) of the state-of-the-art OSCs has reached over 10.0%.Especially,there has been an unexpected breakthrough and rapid evolution of highly efficient organic-inorganic hybrid perovskite solar cells(PSCs),and the PCE has been improved to over 20%.The interface plays a very important role on the performance of both OSCs and PSCs,as well as their stability.It is imperative to control the interface properties and understand the mechanisms for obtaining highly efficient OSCs and PSCs.In this review,we will summarize our research progress on the interface modification of OSCs and PSCs using the electron transport layer and hole transport layer,as well as the molecular template layer.
有机太阳能电池具有柔性、廉价、质轻等优势,多年来一直受到研究人员的大量关注,光电转换效率已经达到10%以上.特别是最近几年,基于有机-无机杂化的钙钛矿太阳能电池发展迅猛,短短几年内,光电转换效率突破了20%.界面对有机和钙钛矿太阳能电池的光电转换效率和稳定性具有举足轻重的作用.因此,研究人员聚焦有机和钙钛矿太阳能电池的界面材料、界面修饰、界面工程等开展了深入研究,并取得了诸多进展.本文主要基于作者课题组多年来在有机和钙钛矿太阳能电池的界面研究所取得的初步进展进行了总结,并对界面材料的发展方向进行了展望,期望满足未来基于印刷技术制备高效率、大面积、柔性有机和钙钛矿太阳能电池的需要.
