Inkjet printing process for kesterite solar cells

RSSfeed Registered Users Posts: 3,810 ✭✭
A research team has developed an inkjet printing technology to produce kesterite thin film absorbers. Based on the inkjet-printed absorbers, solar cells with total area conversion efficiency of up to 6.4 percent have been achieved. Although this is lower than the efficiency records for this material class, the inkjet printing minimizes waste and has huge advantages for industrial production.o0S8XjjOURg
