Research of CH3NH3PbI3 perovskite solar cells had significant attention as the candidate of new future energy. Due to the toxicity, however, lead (Pb) free photon harvesting layer should be discovered to replace the present CH3NH3PbI3 perovskite. In place of lead, we have tried antimony (Sb) and bismuth (Bi) with organic and metal monovalent cations (CH3NH3+, Ag+ and Cu+). Therefore, in this work,...
We developed lead-free perovskite solar cells, because lead is harmful to the human body. In this study, the lead-free perovskite layers were fabricated using antimony, bismuth and silver. Normal (n-i-p) and inverse (p-i-n) structures were tried for the solar cells. By using a lead-free perovskite with silver and bismuth for the normal structure, conversion efficiency of 0.892% was achieved.
Developing low cost CH3NH3PbI3 solar cell utilising earth abundant carbon as a counter electrode in the hole transport layer free structure is promising for practical applications. Here we demonstrated the solution processed CH3NH3PbI3 solar cells by utilising ambient coated carbon layer as hole transport and counter electrodes. The fabricated devices exhibit the advantages in terms of ambient and...
