Photovoltaics are one of the essentials for future energy requirements for sure but in the present time bulky silicon based cells are also asking to be replaced with some new technologies. Organic solar cells are one of the answers. We need to model these devices accurately so that we may precisely understand the obstacles in development of these cells. Same attempt is being done in this thesis. After observing various aspects of organic solar cell modelling some glitches are being tried to remove and based on the same model the behaviour of some new materials have been predicted.
