摘　　要：Kesterite Cu2ZnSn(S,Se)4(CZTSSe)is one of the most promising next-generation thin-film photovoltaic materials due to its environmental friendliness and earthabundant constitutions,excellent optoelectronic properties(high absorption coefficient>104/cm and tunable band gap 1.0–1.5 eV)and high theoretical efficiency(32%).1,2 In 2014,12.6%3 efficiency was achieved by the IBM group using the hydrazine method.Based on the sputtering process,12.62%4 efficiency for CZTSSe and 12.5%5 efficiency for CZTSe have been achieved in recent years.However,the highest efficiency has stuck around 12.6%for several years.Lately,a breakthrough with certified 13%power conversion efficiency(PCE)has been demonstrated for CZTSSe thin-film solar cells,surpassing the dust-covered efficiency record since 2014.3,6 Along with the efficiency advancement of kesterite solar cells,a cost-effective fabrication process with low carbon footprint plays an increasingly important role considering the near-future industrialisation of this kind of solar cell with low energy payback time.
