Abstract

Recent progress in organic (semiconductor) solar cells (OSCs) has led to power conversion efficiencies (PCEs) reaching 20%, with predictions that 25% may be possible. Additional to PCE improvements, significant efforts have been made to address the engineering challenges that have traditionally limited OSCs small area devices often with poor temporal stability. Layer‐by‐layer (LbL) processing of active layers has emerged as a promising approach to tackle these challenges, with numerous state‐of‐the‐art OSCs processed using LbL reported. In this Perspective, recent developments are developed in enhancing OSC efficiency and stability, with a particular focus on the working mechanisms of pseudo‐bilayer heterojunctions (P‐BHJ) and the practical aspects of fabricating high‐performance devices using LbL techniques. By providing insights into LbL processing and the resultant film morphology, it is hoped to contribute to the ongoing efforts to improve OSC efficiency, stability, and scalability and to explore their potential for broader applications such as for example for indoor light harvesting or agrivoltaics.

一层一层加工的伪双层异质结提高了有机太阳能电池的性能

有机（半导体）太阳能电池（OSCs）的最新进展使功率转换效率（pce）达到20%，预测可能达到25%。除了PCE的改进之外，人们还做出了巨大的努力来解决传统上限制OSCs小面积器件的工程挑战，这些器件通常具有较差的时间稳定性。有源层逐层（LbL）处理已成为解决这些挑战的一种有希望的方法，据报道，许多使用LbL处理的最先进的osc。从这个角度来看，最近在提高OSC效率和稳定性方面取得了进展，特别关注伪双层异质结（P - BHJ）的工作机制以及使用LbL技术制造高性能器件的实际方面。通过提供对LbL处理和所得膜形态的见解，希望有助于持续努力提高OSC的效率，稳定性和可扩展性，并探索其更广泛应用的潜力，例如室内光收集或农业光伏。
