In recent years, polymer solar cells have become a low-cost alternative to
silicon solar cells.
Fullerene molecules are often added to polymer solar cells to improve efficiency, but fullerenes are not stable
under light.
By combining PBDB-T polymers and ITIC small molecules, chemists at the Chinese Academy of Sciences have set a new world record for polymer solar cells, increasing the light conversion rate to 11%, higher than most fullerene-containing solar cells
.
Researchers at Linköping University in Sweden characterized photovoltage loss spectra and proposed a way to further improve the efficiency of fullerene-free solar cells, indicating that low-cost, high-efficiency and thermally stable polymer solar cells prepared by roll-to-roll method are one step closer
to commercialization.
