Development of Stable Electrodes for Perovskite Solar Cells

closed

In this Development of Stable Electrodes for Perovskite Solar Cells project, ANU will be working with Monash University to develop new approaches for perovskite electrodes. A variety of integrated electrode structures will be developed and tested for efficiency and stability, and the cost of the developed structures will be assessed. The result is expected to be perovskite solar cells with substantially improved stability that have the potential for commercialisation.Key resultsThe project investigated a range of material configurations, and two types of gold-free electrodes were developed into full cells, one based on a metal layer stack, and one based on carbon. Both show promising efficiency and stability.The metal layer stack cells achieved an efficiency of 19 per cent, which was only 3 per cent less than the efficiency recorded using gold at far higher cost.The project was successful in helping to achieve high efficiency and improved stability using commercially relevant contact materials, which is essential for the commercialisation of the technology.The project findings have the potential to significantly reduce the cost of energy produced by perovskite solar cells.
