Title: Do solar panels suffer from wear & tear?
Post by: neilep on 25/10/2009 11:55:02

As a sheepy I of course absorb sun light through my furry back.  I then utilise this sunlight to make me glow thusly !

Some Solar Panels Solarizing In A Panel Type Of way


...there's discussion indeed about the efficiency of solar panels. I am an authority on this because as a sheepy I am of course very efficient....but what about how long a solar panel lasts ?..there's no moving parts eh ?..Is there any " wear and tear " on a solar panel ?


whajafink ?


hugs & shmishes


mwah mwah mwah !!

I wonder if pehaps they might get sunburn!!!

I don't think they wear out very quickly, but they do have to be kept clean to maintain their efficiency.

Long-life solar cells

Polymer solar cells used to convert sunlight to electricity are degraded by ultraviolet light, which limits their lifespan.

Yang Yang, a materials scientist at the University of California, Los Angeles, US, has a simple solution. He suggests coating the solar cell with a material that converts ultraviolet photons into ones of visible light.

The new "photon conversion material" (PCM) converts harmful UV into longer wavelengths, enhancing efficiency of solar-energy conversion and reducing damage to cells. This should help the solar cells last longer, as well as increase their electrical yield.

The PCM could be made of a liquid, a gel, nanoparticles or a solid, the researchers say. In experiments, they added the polymer blue polyfluorene to solar cells and found that it did indeed reduce the damage caused by UV light.
