recOrbit: Solar power cells are limited by the wavelengths of light they can absorb from the sun. Ideally a solar cell would absorb every wavelength, but to date the goal has not been reached. Silicon, today`s photovoltaic industry standard, is limited in the wavelength range it can 'see` and absorb. A possible solution has been found in indium gallium nitride. Using this material, scientists can tune the material`s response so it collects solar energy from a variety of wavelengths. The more variations...
