Bifacial solar cells based on organic-inorganic perovskite are fabricated with a laminating process. The structure of the devices is ITO/SnO2/CH3NH3PbI3/NiO /ITO, in which both electrodes are the transparent ITO layer. Therefore, the device can receive light from both sides. By laminating the two half-devices, ITO/SnO2/CH3NH3PbI3 and CH3NH3PbI3/NiO /ITO, at high temperature with pressure, the merging of the middle perovskite layers is enhanced. The optimized bifacial PSCs show a Voc of 0.85 V, FF of 0.58, Jsc of 17.53 mA/cm2, and PCE of 8.47%. The photovoltaic performance varies when the light is illuminated from different sides of the bifacial PSCs. With illumination from the SnO2 side, the Voc and Jsc of the PSCs are apparently higher than those from the NiO side, suggesting more severe electron-hole recombination at the NiO /perovskite interface than at the SnO2/perovskite interface.

双面有机-无机钙钛矿太阳能电池的层压制作

基于有机-无机钙钛矿的双面太阳能电池采用层压工艺制造。器件结构为ITO/SnO2/CH3NH3PbI3/NiO/ITO，其中两个电极均为透明ITO层。因此，该装置可以接收来自两侧的光。通过在高温高压下层压两个半器件，ITO/SnO2/CH3NH3PbI3 和 CH3NH3PbI3/NiO/ITO，增强了中间钙钛矿层的合并。优化后的双面 PSC 的 Voc 为 0.85 V，FF 为 0.58，Jsc 为 17.53 mA/cm2，PCE 为 8.47%。当光从双面 PSC 的不同侧照射时，光伏性能会发生变化。在 SnO2 侧的光照下，PSC 的 Voc 和 Jsc 明显高于 NiO 侧的 Voc 和 Jsc，
