Abstract

The elemental composition and content of ITO targets and crystalline silicon heterojunction （HJT） solar cells were calculated and verified by combining theoretical calculation models and experimental tests. Immediately, the hydrometallurgical process were used to leaching and purifying metal indium and the effect of different parameters on the recovery were compared. The results show that the theoretical calculation model of metal indium content in ITO target is consistent with the experimental test results, and 95.56% purity of indium sponge can be obtained by hydrochloric acid leaching and Zn powder replacement. On the basis of this experiment, process optimization was carried out to recover silver and indium metals from HJT solar cells, by which high recovery rate and good economic benefits can be obtained.
