A research team has developed an inkjet printing technology to produce kesterite thin film absorbers. Based on the inkjet-printed absorbers, solar cells with total area conversion efficiency of up to 6.4 percent have been achieved. Although this is lower than the efficiency records for this material class, the inkjet printing minimizes waste and has huge advantages for industrial production.
Researchers have fabricated halide organic-inorganic hybrid perovskite field-effect transistors and measure their electrical characteristics at room temperature for the first time. Hybrid perovskites are a family of crystalline materials that hold great promise in the clean energy world.
Engineering researchers have invented a novel electrical power converter system that simultaneously accepts power from a variety of energy sources and converts it for use in the electrical grid system.
A new study demonstrates that perovskite materials - super efficient crystal structures that have recently taken the scientific community by storm - contain flaws that can be engineered to improve solar cells and other devices even further.
