摘要
During the past decade,nanocrystal solar cells have attracted worldwide research attention due to their high absorption coefficient,broad and tunable absorption range,and promising multiple exciton generation.With joint efforts,great performance breakthroughs have been achieved in the field of nanocrystal solar cell technology,with a certified efficiency of 18.1%for perovskite nanocrystal solar cells(https://www.nrel.gov/pv/cell-efficiency.html)and a record efficiency of 15.4%for PbS nanocrystal solar cells[1].Despite the striking advances,the high toxicity of Pbbased nanocrystal materials raises great concerns when introduced into consumer electronics.Environmental concerns have opened an opportunity for the exploration of ecofriendly alternatives.
