聚合物太阳能电池由于制备工艺简单、重量轻、成本低廉、可制备大面积柔性器件等优点,成为新能源和材料科学中的重要研究方向.经过近10年的发展,聚合物太阳能电池的能量转换效率从2005年的5%提高到目前的10%左右,然而聚合物太阳能电池的活性层形貌仍是制约其能量转换效率的一个重要方面.本文围绕聚合物太阳能电池结构与性能的关系,重点介绍了活性层材料的分子设计(共轭主链调制、烷基侧链优化等)和加工方法(热退火、添加剂、三元溶剂、绿色溶剂等)对其微观形貌的影响,并展望了聚合物太阳能电池未来的发展趋势以及面临的关键挑战.
Due to the advantages of simple preparation process, light weight, low cost and large area flexible devices, polymer solar cells become an important research direction in new energy and materials science.After nearly 10 years of development, the energy conversion of polymer solar cells However, the active layer morphology of polymer solar cells is still an important aspect that restricts its energy conversion efficiency.This paper focuses on the relationship between the structure and performance of polymer solar cells, focusing on The effects of molecular design (such as conjugated backbone modulation and alkyl side chain optimization) and processing methods (thermal annealing, additives, ternary solvents and green solvents) on the micro-morphology of the active layer materials are introduced. Polymer solar cell future trends and the key challenges facing.
