Description

Solar cells made of crystalline silicon account for over 95% of the current world market, and are expected to continue to dominate for many years to come thanks to silicon's combination of earth-abundance, low-toxicity, and suitability for making high efficiency devices. However, despite silicon being one of the most intensively studied materials in existence, there remains room for improvement in our knowledge of many of its properties.

One such area of importance for solar cells is the change in electron and hole mobilities under high illumination levels and as a function of temperature. This project will focus on measuring these properties in high-purity silicon through the application of novel characterisation techniques, building on work performed as part of a previous successful honours project.

The project will mainly involve lab-based experimental work and analysis. Some programming ability will be helpful. Knowledge of photovoltaics or semiconductor physics is an advantage.
