Dr Gaveshana Spelage is a researcher in low-cost solar cell fabrication and their material/device characterization. Currently, he is working on developing alternative electrodes and hole transport materials for perovskite solar cells, which is a new class of solar cells involving cheaper materials to compete with the dominant Silicon solar cells in the market. He acheived Honors degree in Chemistry (Sri Lanka) and Master’s Degree (Sri Lanka) through developing transparent electrodes for Dye Sensitised Solar cells. He then pursued PhD research at Monash University on Application of Inorganic Hole Transport Materials for Perovskite Solar Cells. After completion of his PhD, he gained Industrial experience as a Chemist. He is now a Post Doctoral fellow at School of Chemistry at Monash University and affiliated to the ARC center of excellence in exciton science. The goal of his research is to develop materials/methodologies which will sustain the performance of perovskite solar cells in the long-term.
