我们设计并合成了DPPEZnP-TEH分子，其卟啉环通过亚乙炔桥连接到两个吡咯并吡咯二酮基上。所得材料表现出1.37 eV的非常低的能带隙和至907 nth的宽光吸收。体异质结有机太阳能电池的开路电压为0：78 V，能量损失仅为0.59 eV。这是第一个报告，小分子太阳能电池显示能量损失
We designed and synthesized the DPPEZnP-TEH molecule, With a porphyrin ring linked to two diketopyrrolopyrrole units by ethynylene bridges. The resulting material exhibits a very low energy band gap of 1.37 eV and a broad light absorption to 907 nth. An open-circuit voltage of 0:78 V was obtained in bulk heterojunction (BHJ) organic solar cells, showing a low energy loss of only 0.59 eV,. Which is the first report that small molecule solar cells show energy losses
