Solar Energy

CEI students and faculty are tackling the grand challenge of building high-efficiency solar cells using ultra-low-cost manufacturing processes that are as cheap as printing a newspaper.
We lead groundbreaking research in an array of materials that can be coated and printed and are environmentally benign. For example, hybrid perovskites are a rapidly improving class of materials for printable solar cells. Perovskites already match the efficiencies found in conventional silicon solar cells and allow for whole new device architectures. In addition, electronic polymers have the potential to transform solar cells—they are already improving consumer electronics, lighting, and displays.
