Synopsis

Building-integrated photovoltaic windows are the next frontier in a renewable energy technology for supplying power at the point of use. Luminescent solar concentrator uses a waveguide to trap solar radiation over a large area and collect electricity by PV cells installed along the slab perimeter. Due to its large surface area, it is a promising candidate for photovoltaic windows. In addition, quantum dots are popular in photovoltaic devices due to light-emitting and tunable properties. However, quantum dots used in PV devices so far are known to be toxic and earth-rare. A team led by Brovelli from the University of Milano-Bicocca in Italy has successfully achieved highly efficient and low cost luminescent solar concentrators based on earth-abundant indirect-bandgap non-toxic silicon quantum dots. In this seminar, I will talk about physics behind general photovoltaic devices and review the recently published paper by Brovelli’s group.
