The document summarizes research on luminescent solar concentrators being conducted at MIT. It discusses how luminescent solar concentrators work by capturing sunlight using photoluminescent dyes and concentrating it onto a smaller solar cell, potentially providing advantages over traditional solar panels such as low cost, simplicity, and ability to collect diffuse light without tracking the sun. The research is led by Professor Marc Baldo and is supported by the DOE through its Energy Frontier Research Center program.
