Caroline has been interested in doing work related to combating climate change. This year she has based her EPQ project on investigating solar technology, focusing on a novel type of solar cell call perovskite solar cells. She investigated the working principle of solar cells.

She has also studied other people’s research on methodologies that can improve the performance of a specific type of solar cells -perovskite solar cells. Her research product has produced a literature review of the underlying science of how electricity is being generated in solar cells, and explain how each method works to make the perovskite solar cells better.
