Bootstrap circuits are widely used in dc-dc converters to serve as top-side bias voltage supplies. After explaining how bootstrap circuits work, this article will show how versatile they can be. One ...

Scientists at Germany's Fraunhofer Institute for Solar Energy Systems ISE have demonstrated a triple-junction solar cell with a perovskite-perovskite-silicon subcell configuration. They said the cell ...

Danish researchers have built a selenium solar cell with the highest open-circuit voltage ever reported. They said that with further improvements in the optoelectronic quality of selenium, the device ...
