Faculty Fellow - Energy Lancaster

Research Overview

Lefteris research interests encompass the field of photovoltaics and solar energy conversion. In particular he is interested in developing light harvesting and photon management structures for applications in high efficiency low cost solar cells. Light harvesting structures can be fabricated based on ultra-thin film organic architectures for increased absorption of light and better solar energy utilization. Efficient spectral management of the solar spectrum can be applied to existing solar cell devices towards lower cost of solar electricity.
