Perovskite-cadmium telluride tandem solar cell based on special electrode achieves 24.2% efficiency
An Indian-US research team has fabricated a four-terminal perovskite-cadmium telluride tandem solar cell by utilizing a highly conductive and sputtered transparent electrode to increase the current density of the bottom cell. The tandem device combines a 18.3%-efficient top perovskite cell and a 19.53%-efficient cadmium telluride bottom device.
Fraunhofer ISE unveils M10 TOPCon solar cell with 24.0% efficiency
The German research institute said the new 120 µm thin solar cell could exceed 25% efficiency with the next optimization steps. The device was metalized via screen-printed contact fingers and calibrated by scientists at the Institute for Solar Energy Research Hamelin.
U.S. scientists develop air-bridge thermophotovoltaic cells with 44% efficiency
U.S. scientists have developed a thermophotovoltaic cell that could be paired with inexpensive thermal storage to provide power on demand. The indium gallium arsenide (InGaAs) thermophotovoltaic cell absorbs most of the in-band radiation to generate electricity, while serving as a nearly perfect mirror.
