This week, we bring the first of a two-part conversation on solar PV energy. We chat with Adam Wincukiewicz, a Nanostructural Engineering student from Poland and Enrique Castolo, an Energy Consultant from Mexico, where we talk about photovoltaic cells (solar cells). Adam shares a brief history on the origins of these cells and we also explore the importance of solar PV energy for the global energy future. We also learn about a new generation solar cells, perovskites, that could redefine the future of PV technology!!!
