Apparatus and Method for the Formation of Metal-Halide Perovskite Films

Background Perovskite photovoltaic cells have demonstrated high efficiencies at small scales, both on their own and in conjunction with a bottom cell (such as silicon) to form a tandem. One challenge to scaling up the production of perovskite photovoltaic cells is the lack of effective methods that form uniform perovskite films over different sizes...

Tandem Photovoltaic Module with Diffractive Spectral Separation

Researchers at the University of Arizona have developed a design for a solar concentrating device that has a solar tracker and a diffractive grating as a part of the entrance window or glass for the sunlight to enter through. The technology is designed for use in conjunction with a solar cell for solar panels. The grating delivers specific diffracted...

Double Heterostructure Solar Cells and Photodetectors Based on MgCdTe Absorbers

Multi-layered CdTe solar cell devices have properties that are promising but face low conversion efficiencies and high manufacturing costs. In contrast to typical monocrystalline Si and GaAs materials, CdTe cells are made up of polycrystalline materials and thus, have poor open circuit voltages which are responsible for the low efficiencies. Therefore,...
