Cu2BaSnS4 is an earth-abundant and environmentally benign semiconductor. However, there has been no prior report of colloidal CBTS nanocrystals. For that reason, we developed a colloidal synthesis of CBTS nanocrystals by rational design. Finally, thin films of CBTS nanocrystals grown at room temperature are used as a hole transport layer (HTL) in an organic photodiode yielding a high peak specific detectivity with low noise equivalent power. These results suggest that our colloidal CBTS nanocrystals have potential for optoelectronic applications. |
