This project aims to develop new functional nanoparticles, based on lead halide perovskite materials, for use in light emission and in solar cells. These show extremely promising properties and have the potential to further advance both solar cells and also solid state lighting. In common with many other semiconductor families, there are issues to address concerning the use of low levels of potentially toxic elements (here, lead). Though quantities of these materials used are very low, understanding of the correct protocols to handle such elements safely, through process manufacture, use and disposal is critical and will form an important component of the project.
My research and work experience have been on nanotechnology innovations that could help to boost solar power, which is a technology that can be a key component of our future, green energy supply system due to its easy availability, cleanness and cheap energy resources.
Richard Friend holds the Cavendish Professorship of Physics at the University of Cambridge. He is Director of the Winton Programme for the Physics of Sustainability and of the Maxwell Centre. His research encompasses the physics, materials science and engineering of semiconductor devices made with carbon-based semiconductors, particularly polymers. His research group was first to demonstrate using polymers efficient operation of field-effect transistors and light-emitting diodes. These advances revealed that the semiconductor properties of this broad class of materials are unexpectedly clean, so that semiconductor devices can both reveal their novel semiconductor physics, including their operation in efficient photovoltaic diodes, optically-pumped lasing, directly-printed polymer transistor circuits and light-emitting transistors.
