A simplified architecture leads to efficiencies rivaling conventional silicon solar cells.
A new architecture takes very few processing steps to produce an affordable solar cell with efficiencies comparable to conventional silicon solar cells. This new architecture uses alternative, transparent materials that can be deposited at room temperature, eliminating the need for high temperature chemical doping—the process currently used to increase the electrical conductivity of key surfaces in solar cells.
Proving that this simple design can lead to high conversion efficiencies, turning sunlight into electricity, makes it a useful tool to lower costs and improve performance of a wide range of solar cell designs. Additionally, this simple process could be extended to improve contacts in semiconductor transistors used to speed today’s computers.
