目前, 钙钛矿太阳能电池 (perovskite solar cell, PSC) 的效率 (25.8%) 已经可以与硅基太阳能电池相媲美, 但是长期稳定性不高是其开展商业化应用亟需解决的问题之一. 电化学聚合作为一种制备电活性导电聚合物薄膜的方法, 可以有效降低材料和器件制备的成本; 同时, 化学交联的电聚合薄膜具有较好的稳定性, 能有效提高器件的稳定性. 总结了将交联的电聚合薄膜作为空穴传输层 (hole transporting layer, HTL) 或电子传输层 (electron
transporting layer, ETL) 来开发稳定和高效的钙钛矿太阳能电池, 并论述了电聚合薄膜在钙钛矿太阳能电池未来的研究重点.
The highest certified power conversion efficiency (25.8%) of perovskite solar
cells (PSCs) has rivalled that of silicone-based solar cells. However, the long-term stability
of PSCs should be improved for commercial applications. Electropolymerisation is an
effective method for preparing electroactive and/or conducting polymeric films which allows
for a simple way to reduce the cost of materials and devices. Moreover, chemically crosslinked
electropolymerised films can effectively improve the stability of PSCs. This review
summarises the applications of cross-linked electropolymerised films as hole- or electrontransporting
layers (HTLs or ETLs) for highly efficient and stable PSCs. Lastly, the future
development of PSCs with electropolymerised films is discussed.
