摘要
We report the fabrication of CuI-Si heterojunction solar cells with carbon nanotubes （CNTs） as a transparent electrode. A flexible CNT network was transferred onto tile top of a polycrystalline CuI layer, making a conformal coating with good contact with the underlying CuI. The solar cells showed power conversion efficiencies in the range of 6% to 10.5%, while the efficiency degradation was less than 10% after the device was stored in air for 8 days. Compared with conventional rigid electrodes such as indium tin oxide （ITO） glass, the flexibility of the CNT films ensures better contact with the active layers and removes the need for press-contact electrodes. Degraded cells can recover their original performance by acid doping of the CNT electrode. Our results suggest that CNT films are suitable electrical contacts for rough materials and structures with an uneven surface.
我们作为一个透明电极与碳 nanotubes (CNT ) 报导 CuI-Si 异质接面太阳能电池的制造。一个灵活 CNT 网络被转移到多晶的 CuI 层的顶上，做有与内在的 CuI 的好接触的保角的涂层。太阳能电池在 6% ～ 10.5% 的范围显示出力量变换效率，当在设备在空中被存储为 8 天以后，效率降级是不到 10% 时。与象铟听氧化物(ITO ) 那样的常规僵硬电极相比玻璃， CNT 电影的灵活性与活跃的层保证更好的接触并且为出版社接触电极移开需要。降级的房间能由 CNT 电极做的酸恢复他们的原来的表演。我们的结果建议 CNT 电影与不平的表面是为不平的材料和结构的合适的电的接触。
