Scientists fabricate all-organic solar cell with record 8.7% efficiency

A group of researchers from Japan has achieved a groundbreaking milestone in power conversion efficiency for all-organic solar cells, surpassing the previous record by more than two-fold. The scientists attribute this success to the development of organic electrodes with exceptional conductivity, eliminating the need for acid doping or high-temperature heating. This approach also prevents any harm to the plastic substrates used in the cell.
