Design of Terpene‐Based Eco‐Friendly Solution Process for High‐Performance Organic Solar Cells

Advanced Functional Materials, EarlyView.
High‐performance, terpene‐processed organic solar cells (OSCs) by designing a new green co‐solvent system consisting of eucalyptol (Eu) and 2‐methyltetrahydrofuran (MeTHF) are developed. The OSCs processed from the optimal ratio of Eu and MeTHF achieve the highest power conversion efficiency (PCE) value of 17.3% reported to date for terpene‐processed ...
