説明

<jats:p>An organic solar cell (OSCs) containing double bulk heterojunction (BHJ) layers, namely, double‐BHJ OSCs is constructed via stamp transferring of low bandgap BHJ atop of mediate bandgap active layers. Such devices allow a large gain in photocurrent to be obtained due to enhanced photoharvest, without suffering much from the fill factor drop usually seen in thick‐layer‐based devices. Overall, double‐BHJ OSC with optimal ≈50 nm near‐infrared PDPP3T:PC<jats:sub>71</jats:sub>BM layer atop of ≈200 nm PTB7‐Th:PC<jats:sub>71</jats:sub>BM BHJ results in high power conversion efficiencies over 12%.</jats:p>
