A REVIEW ON ORGANIC PHOTOVOLTAIC DEVICES

Conventional energy resources like thermal power stations and nuclear reactors are threatening the environment by polluting it to the level that will be intolerable for us in near future.To overcome the difficulties, solar cell is the best alternative. It converts sunlight into electricity directly.This study reviews and describes some of the existing research on description of baseline organic solar cell (OSC) structures, advances in Organic Photovoltaic (OPV) research, types of OPV and search for new materials. Then, principle of operation, modeling approaches that have implemented either a one- or a two-dimensional drift-diffusion model to examine OSC structures are reviewed and finally limitations and challenge of the connection between simulation and experimental result have been discussed.There are many scopes to carry on research in this area because of the potential demand and many unresolved issues in this area of research field.
