This project aims to develop new electron microscopy techniques that will unambiguously determine the elusive structures of photoactive perovskite compounds under static and operational conditions, while correlating crystal structure with solar cell device performance. Photoactive perovskites are promising photovoltaic materials, however, many are sensitive to air and irradiation. This has impeded a huge international research effort to determine their structure reliably at the atomic scale.

This project aims to develop a new type of solar cell that is much more efficient than today’s commercial silicon solar cells. Increasing cell efficiency is one of the most effective ways to reduce the cost of solar electricity, but silicon cells are approaching practical and theoretical limits. This project expects to boost the efficiency of silicon solar cells by adding a low-cost solar cell on top to create a tandem device. The expected outcome is a solar cell that can convert more than 30 per cent of incident sunlight into electricity, compared to 20-25 per cent for current cells. Developing cheap, high efficiency solar cells should further reduce the cost of solar electricity, and accelerate the uptake of clean energy.Read moreRead less
