(Phys.org)—Before there were lasers, there were masers—devices that operate in the microwave regime and other wavelengths that are longer than those of visible light. But while the first masers were built back in the ...
Organic photovoltaic material offers great promise for solar energy. The semi-conducting plastic is lightweight, flexible, relatively inexpensive, and easy to make. The problem is that, unlike inorganic photovoltaic material, ...
