47th IEEE Photovoltaic Specialists Conference
June 15 - August 21, 2020
PVSC 47 Virtual Meeting
A hot carrier solar cell is a device that offers the potential to reduce thermalization losses in the material and could potentially double the efficiency of single junction solar cells (30% to > 60%), which would be a significant breakthrough for the photovoltaics community. Although these hot carrier devices have been the source of a considerable amount of research over the last 10 to 15 years, the realization of a practical solution to this challenging problem has thus far eluded researchers. In this topical discussion, several experts in the community will discuss the evolution of this field. Specifically, recent progress towards the realization of hot carrier solar cells in which several experimental works have demonstrated the potential of such systems. Despite this progress several significant challenges remain. It is expected this new progress and the outlook for this field in general, will stimulate considerable debate from both the panel and the wider live audience.
