Enhanced Organic Photovoltaics (EOPV)



Solar energy is renewable, eco-friendly and found in abundance. If optimized properly, it can fulfill the energy requirements of contemporary world. At present, the efficiency of Silicon based solar cells lies between 10-15% and also it is not cost effective. Due to certain limitations of Si-based solar cells researchers are moving towards an alternative i.e. Organic Semiconductors. Organic Semiconductors possess properties like good electrical conductivity, mechanical strength, optical absorption, photoluminescence, easy and cheap manufacturing etc. In this paper, we aim to design a solar cell that intercepts most of the energy spectrum of sunlight and converts it into electricity efficiently. After having a detailed study of latest researches and analyzing the properties of many substances, we created a theoretical model of polymer based solar cell. The model uses aluminum studs at the interface and Bulk-Heterojunction of Single Walled Carbon Nanotubes (SWCNTs) and Organic polymer- Poly Butylene Terephthalate (OP-PBT) as an electron donor and acceptor respectively. We will explain how our model –EOPV intercepts and interacts with the photons of different wavelengths and how these photons penetrate and produce ‘excitons’ which in turn generates photocurrent. Based on certain assumptions and calculations our EOPV model exhibits the efficiency of more than 40% which is comparatively better than existing conventional models.
