Defects in light-absorbing layers have indelible effects on the performance of kesterite solar cells. In the development of CZTSSe solar cells, a good understanding and effective engineering of the defects in CZTSSe absorbers have been demonstrated to be crucial factors for the fabrication of high-efficiency CZTSSe solar cells.
Radiative recombination is considered as the most likely loss mechanism in CZTS and CZTSe based thin film solar cells. Tail bands and Gaussian defect states formed near the conduction band act as trap sites for electrons and are quite detrimental in the operation of the solar cells.
Experimental studies identify the formation of intrinsic point defects near the front interface (e.g., Fermi level pinning due to Cu-Zn antisite defects) and within bulk (bulk recombination due to deep defects) as the key culprits behind the undesirable performance of solar cells.
Kesterite Cu2ZnSn (S,Se)4 (CZTSSe) is one of the most promising materials for photovoltaics. CZTSSe solar cells have achieved an efficiency of 15.1%, yet further improvements have been challenging. Defects in light-absorbing layers have indelible effects on the performance of kesterite solar cells.
Under stoichiometric conditions, there are still high concentrations of [2Cu Zn + Sn Zn] defect clusters which cause high concentration band tail states in the absorber , . Therefore, the defects in CZTSSe thin-film solar cells should be effectively controlled to improve device performance.
Based on the current understandings and perspectives, gaining control of the intrinsic defect and defect cluster is a serious challenge in developing high-performance kesterite solar cells.
Among these defects, Sn-related defects like Sn Zn and associated [Cu Zn +Sn Zn] clusters have been widely recognized as major deep-level defects, and a large …
