Modern computer chips can construct nanoscale structures. So far, only these tiny structures can be formed on top of silicon chips, but now a new technology can create nanoscale structures in a layer beneath the surface. The inventor of this method stated that it has broad application prospects in the fields of photonics and electronics, and one day, people can manufacture 3D structures on the ent...
A team of scientists at the Technical University of Denmark has created a selene-based solar cell by replacing thermal annealing with a new laser annealing strategy."In our work, we investigated the potential of this laser annealing strategy specifically for selenium thin film solar cells, and we report a new world record for fill factor, a new world record for ideal factor, and the most advanced ...
