Ternary Organic Solar Cells: Recent Insight on Structure-Processing-Property-Performance Relationships

This article presents recent advances in the ternary organic solar cell (TOSC), such as technological interventions from the material design to the device performance, which led to more than 19% power conversion efficiency (PCE). The research and development in TOSCs reported in the past decade have been inspiring and promising in terms of molecular processing to device properties for low-power devices and building integrated photovoltaics applications. Many of these are still in the early phase, enabling researchers to explore more and flourish. The research community has made numerous efforts to address the different aspects to enhance the efficiency and stability of the TOSCs. Therefore, the objective of this article is to review the recent advances in TOSCs and present a comprehensive discussion in this regard. This review also identifies and suggests the possible outlook for the critical issues associated with TOSCs, along with future perspectives.
