An all-solid-state, lightweight, flexible, and wearable polymer solar cell (PSC) textile with reasonable photovoltaic performance has been developed. A metal textile electrode made from micrometer-sized metal wires is used as the cathode, and the surfaces of the metal wires are dip-coated with the photoactive layers. Two ultrathin, transparent, and aligned carbon nanotube sheets that exhibit remarkable electronic and mechanical properties were coated onto the modified metal textile at both sides as the anode to produce the desired PSC textile. Because of the designed sandwich structure, the PSC textile displays the same energy conversion efficiencies regardless of which side it is irradiated from. As expected, the PSC textiles are highly flexible, and their energy conversion efficiencies varied by less than 3% after bending for more than 200 cycles. The PSC textile shows an areal density (5.9 mg cm(-2)) that is lower than that of flexible film-based PSCs (31.3 mg cm(-2)).
已经开发出一种具有合理光伏性能的全固态、轻量、柔韧和可穿戴的聚合物太阳能电池（PSC）纺织品。使用由微米级金属线制成的金属纺织品电极作为阴极，并对金属线的表面进行浸涂以形成光活性层。将两个具有优异的电子和机械性能的超薄透明且对齐的碳纳米管片分别涂覆在经过改性的金属纺织品的两侧作为阳极，以制备所需的 PSC 纺织品。由于采用了设计的夹层结构，无论从哪一侧照射，PSC 纺织品都具有相同的能量转换效率。正如预期的那样，PSC 纺织品具有很高的柔韧性，经过 200 多次弯曲循环后，其能量转换效率的变化小于 3%。PSC 纺织品的面密度（5.9mg/cm^(-2))低于柔性薄膜基 PSCs（31.3mg/cm^(-2))。
