New Technique Could Harvest More of the Sun''s Energy
However, the photovoltaic cells now used to turn sunlight into electricity can only absorb and use a small fraction of that light, and that means a significant amount of solar energy goes untapped. A new technology created by researchers from Caltech, and described in a paper published online in the October 30 issue of Science Express, represents a first step …
Solar cells and absorption | Resource | RSC Education
Investigate which wavelengths of light have the highest energy by measuring the current produced when a solar cell is illuminated with coloured light. This activity demonstrates the ability of solar cells to absorb at different wavelengths of the electromagnetic spectrum and shows how the more it can absorb, the more power it produces.

The silicon atoms in a photovoltaic cell absorb energy from light wavelengths that roughly correspond to the visible spectrum. The cell has silicon mixed with two different impurities that produce positive and negative charges. ... If you carefully plot a solar cell''s output energy against the wavelength of incoming light, your graph will show ...
Solar cells require certain wavelengths in the light spectrum to generate useful amounts of electricity. Anatomy of a Solar Cell A solar, or photovoltaic, cell is a two-layer sandwich of silicon; one layer, called N-type, contains traces of elements such as arsenic to give the material a negative electric charge; the second layer, called P-type ...
8.2 The Light-Dependent Reactions of Photosynthesis
Our retinal pigments can only "see" (absorb) wavelengths between 700 nm and 400 nm of light, a spectrum that is therefore called visible light. For the same reasons, plants, pigment molecules absorb only light in the wavelength range of 700 nm to 400 nm; plant physiologists refer to this range for plants as photosynthetically active radiation.
