I use a large fresnel lens to test the effect of concentrated sunlight on a solar cell. To keep the solar cell cool I immerse it in mineral oil. I measure the voltage, current and the temperature. But I also test it without the cooling and sure enough, the solar cell is destroyed by the concentrated sunlight. The fresnel lens is one I got from a rear projection TV.
See also my video all about fresnel lenses, “Fresnel lens – what is it, testing focal length, solar heat generated”:
To watch my video about the fresnel lens combined with a mirror, “Fresnel lens and mirror solar cooker cast iron pan”, see:
And for the video “What is Fire” watch:
In this one I use a small fresnel lens to concentrated sunlight onto a solar cell made from a transistor “How to Make a Solar Cell using a Transistor (2N3055)”:

In case you’re curious where I normally use this mineral oil, it’s for the Cockroft-Walton voltage multiplier board for my 75kV high voltage power supply. You can see it here:

The photo of solar power in winter was taken by me while working with Ottawa Solar Power (http://ottawasolarpower.com) on a solar installation job.
