Developing active-layer systems with both high performance and mechanical robustness is a crucial step towards achieving future commercialization of flexible stretchable organic solar cells (OSCs). Herein, we design synthesize series acceptors BTA-C6, BTA-E3, BTA-E6, BTA-E9, featuring the side chains hexyl, 3, 6, 9 carbon-chain ethyl ester end groups respectively. Benefiting from suitable phase separation vertical distribution, PM6:BTA-E3-based OSCs processed by o-xylene exhibit lower energy...
