Abstract:

Organic solar cells(OSCs) have been the top research hotspot in the field of solar cells due to their advantages such as light weight, flexibility, and ease of large area preparation. Currently, the power conversion efficiency(PCE) of single junction OSCs has exceeded 19%. In-depth study of active layer film formation kinetics and thermodynamics has significant implications for enhancing the performance of organic solar cells. Meanwhile, the development of large-area printing preparation technology is beneficial to promoting the commercialization of OSCs. This review systematically summarizes the representative results in OSCs based on pseudo-planar heterojunction(PPHJ) structures, focuses on the research progress of interface engineering modulation and preparation process optimization in organic photovoltaic devices, and provides an outlook on the future development of high-performance large-area OSCs.

Key words: Organic solar cell, Pseudo-planar heterojunction, Vertical phase separation, Green printing
