摘　　要：柔性透光电极因其在可穿戴光电器件领域具备巨大的潜力而吸引了极大的关注。文章以静电纺丝法制备了用于太阳能电池的银/聚酰亚胺/聚氨酯(Ag/PI/PU)柔性纳米纤维膜电极。在优化纳米纤维的组成和纤维覆盖率后,柔性电极的透过率和方块电阻达到80.8%和21.8Ω/□。并且,柔性电极具有较好的力学稳定性,当拉伸应变达到160%时,电极的电阻率仅增大至24.6Ω·cm;在拉伸应变为100%时循环拉伸49次以后,相对电阻率仅增大至0.11。以Ag/PI/PU柔性电极为基底组装的太阳能电池,其光电转换效率达到2.23%。Flexible light-transmitting electrodes have received widespread focus due to tremendous potential applications in the field of wearable photoelectronic devices.In this paper,the flexible transparent silver/polyimide/polyurethane(Ag/PI/PU)nanofibers(NFs)electrodes for solar cells were prepared using electrostatic spinning.After the composition of the nanofibers and nanofibers coverage area was optimized,the transmittance and the sheet resistance of the flexible electrodes were 80.8%and 21.8Ω/□,respectively.Besides,with excellent mechanical stability,the stretchable electrode resistivity only increased to 24.6Ω·cm under tensile strain of 160%,and the relative resistivity merely increased to 0.11 after 49 tensile cycles under 100%strain.For solar cells fabricated based on the flexible electrode,the power conversion efficiency reached 2.23%.
