To evaluate their performance, we constructed organic solar cells using PTB7/Y6 and PTB7-b-PNDI active layers, which were deposited on PET substrates coated with PEDOT: PSS. The ternary solar cells demonstrated an excellent power conversion efficiency after being stretched by 38%. The stretchable organic solar cells were spin-coated on the flexible substrate. The electrodes were formed via liquid metal drop-coating. Solar cell devices based on PET/PH1000/PEDOT: PSS and PTB7:Y6: 5% BCP active layer materials show better stretchability than the normal solar cells. The PTB7:Y6: 5% BCP-based stretchable organic solar cell achieves a high PCE of 12.3%, and a PCE of 7.8% after stretching. Incorporating block copolymer additives improves the mechanical properties of organic solar cells, thereby enabling superior stretchability.
