摘　　要：聚合物太阳能电池由于质量轻、成本低、柔韧性好及制备工艺简便等优点而具有巨大的潜在应用价值,是太阳能电池发展的新方向。但是聚合物太阳能电池的能量转换效率较低,达不到商业化应用的要求,如何提高电池效率仍是目前研究的重点。聚合物材料和光敏层的形貌是影响太阳能电池性能的两大要素,从机理方面分析了限制太阳能电池效率的一些因素,介绍了聚合物材料的新进展,探讨了聚合物材料设计的原则及方法,着重探讨了形貌对太阳能电池性能的影响以及改进形貌的方法及其理论基础,并展望了聚合物太阳能电池未来的发展趋势。Polymer bulk heterojunction solar cells have great potential for practical applications owing to their light weight, low cost, good flexibility and simple fabrication. Significant efforts are made to improve photoelectric conversion efficiency of polymer solar cells, but it＇s still hard to meet the requirements of commercial applications sufficiently. How to improve the conversion efficiency is the pivotal problem. The critical factors limiting polymer solar cells＇ conversion efficiency are analyzed and recent development and the design rules of novel materials for polymer solar cells are reviewed, The effect of morphology for power conversion efficiency and the possible strategies for optimizing the morphology are summarized and highlighted.
