摘要
有机-无机杂化太阳电池是一种由提供电子的有机聚合物和接受电子的无机半导体构成的新型电池,常用的无机半导体材料有纳米氧化锌(ZnO)、二氧化钛(TiO2)、硫化镉(CdS)等。杂化太阳电池在研究过程中存在一些问题,如电池中电子传输效率差、太阳能利用率低、无机半导体和有机聚合物之间化学不兼容以及由此导致的光电转换效率低等。围绕这些问题,针对以ZnO半导体材料为电子受体的太阳电池,从电子受体材料形貌、电子给体材料种类以及添加不同修饰层等方面论述了电池光伏性能的优化方法,对该电池的未来发展趋势进行了展望。电池性能的优化,为低成本、高效率应用该类杂化太阳电池带来了希望。
Organic-inorganic hybrid solar cell is a new type of solar cell,with its organic polymers to provide electrons and inorganic semiconductors to accept electrons.The commonly used inorganic semiconductors are nano-sized zinc oxide(ZnO),titanium dioxide(TiO2),cadmium sulfide(CdS),etc.There are many problems needing to be solved in the research process of hybrid solar cells,such as the poor electron transport efficiency,low utilization of solar energy,chemical incompatibility between inorganic semiconductors and organic polymers,and the consequently caused low photoelectric conversion efficiency.Around the above issues,concerning the solar cell with the ZnO semiconductors as electron acceptor,the photovoltaic performance optimization methods are discussed from the aspects of electron acceptors,electron donor materials and the addition of modified layers for the ZnO-based solar cell,and the future development tendency of the hybrid solar cells is also prospected.The optimization of cell performance has brought hope to the low cost and high efficiency application of this hybrid solar cell.
