The Effect Of Thermal Annealing On The Efficiency Of Semi-Transparent Organic Solar Cells

Abstract

Solar cells provide an alternative and environmentally friendly source of energy from the sun. In this project, we fabricated organic solar cells and characterized their conduction under a simulated solar light source. The organic cells have an active region composed of electron-donor poly(3-hexylthiophene) (P3HT) and electron acceptor penyl- C61-butyric acid methyl ester (PCBM) materials to form a pn heterojunction. This study was investigated, we analyzed the effect of annealing P3HT:PCBM polymeric blends on cell efficiency while maintaining the substrates under ambient atmosphere. The effect of annealing on the solar cell efficiency by measuring their current-voltage characteristics given these conditions, and found an indirect correlation between efficiency and annealing temperature.
