Bulk heterojunctions push the photoresponse of perovskite solar cells to 970 nm†
To expand the photoresponse of perovskite solar cells, we implanted bulk heterojunctions to make integrated solar cells with a structure of ITO/PEDOT/CH3NH3PbI3/(PDPP3T–PC61BM)/Ca/Al. The new cells gave higher Jsc than perovskite solar cells due to additional photocurrent contribution from the bulk heterojunction. This innovative design shows promise for the development of next-generation solar cells.
