Multidimensional Modelling of Organic Solar Cell

Modelling and analysis of multidimensional organic solar cell (OSC) with different geometry design can give the researchers an opportunity to explore the electrical and optical properties of the OSCs, enhance the cell efficiency, and then take it to the implementation of the new design. In this paper, we first model and analyse a one dimensional solar cell with the P3HT (poly (3-hexylthiophene)): PCBM (phenyl-C61-butyric acid methyl ester) material to illustrate how the material's characteristics link to the electrical properties based on the Shockley-Read-Hall recombination and carrier generation model. Then, we extend the design to a three dimensional model with a new inverted design of an organic solar cell using P3HT: PCBM and silver grids, for light trapping.
