Solar electricity has been growing exponentially for decades. With each doubling of cumulative installed capacity, costs have been dropping steadily. Currently new solar electricity plants are competitive with existing power plants that burn coal. In this session, Zachary Holman ’05 will share his expertise in cutting edge solar cell research further increasing efficiencies and lowering costs. Peter Lilienthal ’78 will explore new applications that radical drops in solar costs are enabling, and Chris Greacen ’91 will discuss the scaling of deployment of village-scale solar mini grids electrifying rural communities in Sub-Saharan Africa and Southeast Asia.

This event took place on 6/6/21 as a part of the Alumni College 2021 program.
