Application progress of hole-transport-material-free perovskite solar cells with carbon materials as counter electrode
At present, for the highefficient PSCs, the counter electrode based on precious metals like gold and silver and expensive hole transport material are standard configuration, which hinders seriously the promotion and development of PSCs. Therefore, it is urgent to develop lowcost counter electrode and hole transport materials. As well known, the carbon materials possess low price, stable chemical property, good electrical conductivity and strong hole collection ability. In recent years, the research on carbonbased PSCs without hole transport layer (HTL) has developed rapidly. In this paper, the device structure and working principle of carbonbased PSCs were introduced, the application progress of various carbon materials such as graphite/carbon black, carbon nanotubes, conductive carbon paste, carbon ink, grapheme in the counter electrode of perovskite solar cells was reviewed. The limitations of existing research work were pointed out, and the future development directions were briefly described.
