The photovoltaics field has been revolutionized by the emergence of lead-based hybrid perovskites. These materials are high quality semiconductors that can be deposited cheaply, from solution, at low temperature. However, the toxicity of lead and stability issues of these perovskites are driving a new search for more benign and stable alternatives. Inspired by these success and combined with my personal interest for topics related to energy I am now pursuing a PhD in materials science. Within my project we will try to find other chemically processable Bi based compounds which resemble the same defect tolerance as lead based perovskites, with the ultimate goal of making solar energy cheaper and more efficient.
