Solar panel energy related to color of visble light.

Rumors from 2014 suggest apple was exploring ways to put solar panels in the apple. They spend all day baking in the sun but that doesn t mean solar panels capture all the light that hits them. The transparency of some existing windows is similar to the transparency of the solar cells forrest s group reports in the journal proceedings of the national academy of sciences. Therefore if solar panels can extract power from wavelengths as low as 300 nm to 1 200 nm then it is logical to think that solar panels could extract some energy from this source.

Previous transparent solar cells have light utilization efficiencies of roughly 2 3 but the indium tin oxide cell is rated at 3 5 and the silver version has a light utilization efficiency of 5. Visible light is a very small part of the electromagnetic spectrum a continuous range of energy wavelengths that includes radio waves light and x rays. White light that we see from the sun includes all colors of the visible spectrum and ranges in wavelength from about 400 nanometers nm to about 780 nm. Visible light waves measure between 400 and 700 nanometers although the sun s spectrum also includes shorter ultraviolet waves and longer waves of infrared.

A see through panel like the one described by erasmus could offer even more chances to place panels in gadgets. Generally speaking solar cells are capable of harnessing visible light for energy. Solar cells generate an electrical current when light hits their surface. Comsol on the other hand fluorescent lights were defined and designed to be located inside the visible region of light.

Solar cells vary in their response to different wavelengths or color of light. Transparent solar panels can redirect this light to generate energy and reduce the building s load on the electric grid. Rather than throwing that energy away transparent solar panels could use it to take a bite out of the building s electricity needs. The team achieved 8 1 efficiency and 43 3 transparency with an organic or carbon based design rather than c.

Glass on buildings have a coating to reflect and absorb some of the light for reducing brightness heat inside and rather than discarding that energy away transparent solar panels could harness it. Light spectrum and wavelength.
