A lead-free solar material developed by Berkeley Lab scientists offers a simpler and more sustainable approach to solar cell manufacturing. The advance could also benefit halide perovskites, a promising solar technology that requires much less energy to manufacture than silicon.
Nylon 6-6 is used to make many products that require strength, durability and weather resistance, but its synthesis requires the endangered element zinc as a catalyst. Now, researchers have developed “greener” methods that use different metals. They will present their results at ACS Fall 2021.
Produced in a sustainable way, synthetic fuels contribute to switching mobility to renewable energy and to achieving the climate goals in road traffic. In the mobility demonstrator “move” Empa researchers are investigating the production of synthetic methane from an energy, technical and economic perspective – a project with global potential.
Scientists improved the performance of bismuth vanadate, an electrode material for converting solar energy to hydrogen—an energy-dense and clean-burning fuel.
Thermoelectric devices, which use the temperature difference between the top and bottom of the device to generate power, offer some promise for harnessing naturally occurring energy. In Applied Physics Letters, authors tested a device made up of a wavelength-selective emitter that constantly cools the device during the day using radiative cooling. As a result, the top of the device is cooler than the bottom, causing a temperature difference that creates constant voltage through day and night and various weather conditions.
