Gounden, Denisha published the artcileMetallophthalocyanines in a ternary photoactive layer (P3HT:MPc:PC70BM) for bulk heterojunction solar cells, Synthetic Route of 91-15-6, the main research area is metallophthalocyanine PHT PCBM bulk heterojunction solar cell.
Novel bulk heterojunction (BHJ) organic photovoltaic (OPV) solar cells have been fabricated by introducing a series of metallophthalocyanines (MPcs) into a blend of a poly(3-hexylthiophene-2,5-diyl) (P3HT) and [6,6]-Ph C70 butyric acid Me ester (PC70BM) photoactive layer. Sixteen MPcs have been synthesized with due consideration of the metal type and valency, functionalised ligand moieties and their resp. mol. energy levels. The MPcs were expected to act as an electron cascade material that improves the photovoltaic performance in a two-fold manner: first, to provide an efficient energy level offset between the polymeric donor (P3HT) and the fullerene-based derivative acceptor (PC70BM) to enhance charge transfer and reduce recombination within the OPV solar cells, and second, to harvest a greater portion of the solar spectrum as MPcs are associated with absorption near the near-IR region. BHJ OSCs were fabricated in the following inverted configuration: ITO/TiO2/P3HT:MPc:PC70BM/WO3/Ag and were investigated for their optimum photovoltaic performance. The BHJ OSCs comprising P3HT, PC70BM and the manganese MPc (MnPc) series photoactive layer displayed the best PCEs in the range of 2.36-2.62% which were approx. 47.5-63.7% higher than those of the binary reference BHJ OSCs.
