Development of Stable Electrodes for Perovskite Solar Cells Project Results and Lessons Learnt

Perovskites are an exciting new class of materials for solar cells because they are low cost and can be used to make high efficiency solar cells. Key advantages are that they can be cheaply deposited at room temperature, they have high material quality, and they can be tuned to absorb light across the solar spectrum. A limitation of perovskite cells is that so far the highest efficiency solar cells have used high cost electrodes with limited stability. This project is developing novel multi-layer integrated contacts that can achieve high efficiency, low cost, and improved stability. A variety of integrated electrode structures are being developed and tested for efficiency and stability, and the cost of the developed structures will be assessed. Development of improved electrodes is expected to substantially accelerate the commercialization of this promising technology, leading to reduction in the cost of solar energy.
