📍 Hosted at Tam Wing Fan Innovation Wing Two ()
⚡Speaker: Professor Christos N. Markides, Professor of Clean Energy Technologies, Head of the Clean Energy Processes Laboratory, Department of Chemical Engineering, Imperial College London
Photovoltaic (PV) panels are typically less than 20% efficient in delivering electricity from the Sun’s energy. The efficiency losses are especially pronounced when PV panels are exposed to high irradiance conditions on warm, sunny days, which lead to higher temperature operation. Of the total amount of sunlight incident on PV panels, over 70% is lost to the environment as waste heat. This loss has motivated the development of ‘hybrid’ PV-thermal (PV-T) collectors, which combine PV cells with a contacting fluid. The fluid recovers waste heat from the cells, thus delivering a potentially useful thermal output, while simultaneously cooling the cells and increasing their electrical efficiency. Recently, a new concept that we refer to as multifunctional ‘PV-X’ collector technology has emerged, in which secondary processes are integrated synergistically with the PV cells, exploiting the available waste heat to perform additional functions directly within the collector. ⚡
In this talk, Professor Christos N. Markides will present conventional and advanced PV-T and PV-X collector concepts and designs, along with their underlying operational principles. He will explore opportunities for further developing these technologies and examine how new materials can drive improvements from the component to the system level, while discussing the potential of integrating these technologies into broader solar-energy systems capable of providing cooling, heating, power, fuels or clean water.
