Small-molecule solar cells get 50% increase in efficiency with optical spacer
Quantum dot LED approaches theoretical maximum efficiency
New hybrid material simplifies organic transistor design
Polymer mold makes perfect silicon nanostructures
Using molds to shape things is as old as humanity. In the Bronze Age, the copper-tin alloy was melted and cast into weapons in ceramic molds. Today, injection and extrusion molding shape hot liquids into ...
Study shows microbes may accelerate loss of permafrost in Greenland
Solar cell polymers with multiplied electrical output
One challenge in improving the efficiency of solar cells is that some of the absorbed light energy is lost as heat. So scientists have been looking to design materials that can convert more of that energy ...
