ARCHITECTURES AND CRITERIA FOR THE DESIGN OF HIGH EFFICIENCY ORGANIC PHOTOVOLTAIC CELLS

摘要

organic photovoltaic cell is an anode and a cathode, and the anode and the cathode between the includes a plurality of the organic semiconductor layer. Is at least one of the anode and the cathode is transparent. A number of each of the two adjacent layers of the organic semiconductor layer is in direct contact. A plurality of the organic semiconductor layer comprises two sets of a middle layer, and three or more layers consisting essentially of a photoconductive material. The first set of three or more layers between the middle layer and the anode. Each layer of the first set is composed essentially of a different organic semiconducting material having a higher LUMO and HOMO higher than the materials of the adjacent layers close to the cathode of the plurality of the organic semiconductor layer; Second set of three or more layers is between the intermediate layer and the cathode. Each layer of the second set consists essentially of a different organic semiconducting material having a lower LUMO and LUMO lower than the material of the adjacent layer close to the anode of the plurality of the organic semiconductor layer. ;
