制备了一种有机铅卤钙钛矿-有机本体异质结杂化串联太阳能电池。采用紫外可见吸收光谱、原子力显微镜对薄膜形貌进行了表征。结果表明：有机本体异质结层可以有效改善钙钛矿的表面形貌,增强了可见光的吸收。优化后的串联结构电池的短路电流可达19.14 mA /cm2,开路电压为0.76 V,光电转换效率达到了6.54%。钙钛矿电池和有机本体异质结电池串联结构可以同时提高短路电流及填充因子,二者具有较好的相容性和协同作用。

An integrated perovskite/organic bulk-heterojunction ( BHJ) photovoltaic device was fabricated for effi-cient light harvesting and energy conversion. The structure of the solar cells consists of two photovoltaic layers, name-ly a methylammonium lead iodide ( CH3 NH3 PbI3 ) and poly ( 3-hexylthiophene ) ( P3HT ) blended with metha-nofullerene [6,6]-phenyl C61-butyric acid methyl ester (PCBM) organic BHJ active layer. The power conversion ef-ficiency (PCE) of 6. 54% was achieved in the integrated device with a Jsc of 19. 14 mA /cm2, a Voc of 0. 76 V, and a FF of 45. 0%. Compared to that of CH3 NH3 PbI3/PCBM planar device, the enhanced performance indicates that the BHJ film absorbs light and contributes to the current density of the device. Our research further demonstrates the compatibility and synergistic potential of the perovskite and organic bulk-heterojunction ( BHJ) photovoltaic device.
