Research project: Thin Film Transparent Graphene Electrode for Organic Solar Cell (open for PhD application)

Currently Active: 
Yes

Silicon based solar cell technology has been established as the main source in PV solar cells. The solar cell efficiencies vary from 8 to 29%. Though the silicon based efficiency is high, use of silicon technology has major drawbacks; with high production costs and suffers a decrease in performance under illumination, thereby limiting lifetime, durability and stability. Therefore new material such as 1D and 2D graphene has shown potential as the emerging technology for electrodes in organic solar cells.

New material such as 1D and 2D graphene has shown potential as the emerging technology for electrodes in organic solar cells. The use of thin film technology in graphene is expected to revolutionize the manufacturing process by a reduction in cost as the layers become much thinner and less purification processes will be required. The OSCs fabricated using thin film graphene is expected to show a power conversion efficiency of more than 70% indicating that graphene indium-free transparent electrode is a potential substitute for the conventional ITO electrode for use in cost-efficient OSCs.
