A push-pull porphyrin dimer with multiple electron donating groups has been synthesized as a sensitizer with an excellent light-harvesting ability in the near-infrared region for dye-sensitized solar cells (DSSCs). The DSSC based on the sensitizer...
Due to the high conversion efficiency, organic-inorganic hybrid perovskite (CH3NH3PbI3) solar cells are investigated for new practical energy resources for our future society. However, the perovskite solar cells have been quite unstable devices. I...
