Simulation of polymer solar cell characteristics is presented in this study. The solar cells are made of materials such as the following: Poly (3-hexylthiophene): [6, 6]-phenyl C61- butyric acid methylester (P3HT: PCBM) and poly[2,1,3-benzothiadiazole-4,7-diyl[4,4- bis(2-ethylhexyl)-4H-cyclopenta[2,1-b:3,4-b']dithiophene-2,6-diyl]]: [6, 6]-phenyl C61- butyric acid methylester (PCPDTBT: PCBM) are used as active layer materials. Analysis of Microelectronic and Photonic Structures One Dimension (AMPS-1D) is a computer simulation tool for solar cell device characteristics. The first part of this study focuses on the performance and comparison of current-voltage (I-V) simulations of indium oxide (In2O3) and tin oxide (SnO2) (ITO) and poly (3,4-ethylenedioxythiophene): poly (styrenesulfonate) (PEDOT: PSS) as transport layer. The other comparison is between single polymeric solar cell and tandem polymeric solar cells by current-voltage (I-V) simulations. Photovoltaic effect permits the conversion of sunlight to electrical energy by excitons. Excitons travel from highest unoccupied molecular orbital (HOMO) level of conjugated polymer material to lowest unoccupied molecular orbital (LUMO) level of fullerene material. Exciton is regarded as a bound state of electron and hole.
