Structure and Reflectance of a b-Si. Aalto Researchers recently solved the issue of surface recombination in black silicon solar panels, meaning future solar technology may be both less expensive and more efficient, at 22% and above efficiency. (via Aalto University) Since it takes so long to pay off a solar panel, and without government subsidies.. is solar a good option? Or should it stay in the research world? As people strive to find alternative energy sources, researchers from Aalto ...
"Photographs of upconversion in a cuvette containing (a) an optimized cadmium selenide /9-ACA/DPA and (b) a cadmium selenide /ODPA/DPA mixture. (9-ACA: 9-anthracenecarboxylic acid; ODPA: octadecylphosphonic acid; and DPA: 9,10-diphenylanthracene.) They were excited with a focused continuous wave 532-nm laser. The violet DPA output in (a) swamps the green beam that is clearly seen in (b), where no upconversion takes place. This indicates the enhancement of the upconverted fluorescence by the 9-AC ...
