Nanostructured Upconvertors for Advanced Solar Energy Harvesting

点击翻译按钮获取中文摘要

The efficiency of many solar energy conversion processes, such as solar photovoltaic and solar hydrogen, can be improved by management of the solar spectrum. One photon management strategy is up-conversion, whereby two lower energy, unusable photons are conjoined to bring about a higher energy photon. Photochemical up-conversion, where light harvesting and energy-pooling is performed in organic molecules, has been rapidly advanced in recent years, and promises to deliver the efficiencies required to find real-world application. This project brings together laser spectroscopy, organic and materials chemistry and nanotechnology to realise efficient up-convertors which will be applied to solar cells and solar fuels.
