Fresnel Lens Solar Power

Solar power concentration?
Hi everyone! Let’s say I use a fresnel lens to focus light into a solar cell.. and lets assume I am able to keep the solar cell below 120 deg Celsius (maybe by introducing a blower to ventilate or something) .. will it’s useful life still be shorter? (please disregard the fact that using a blower as ventilation consumes energy)..
Then lets say I can focus 1000 suns into just 1 solar cell but my some miracle am still able to maintain the temperature.. will the energy it generates have diminishing returns?
I’ve been daydreaming about solar energy and hope someone would enlighten me..
Thanks!
There is a whole field of concentrated Photovoltaic power. A number of ways have been considered to do this using either lenses or mirrors. Such an array typically involves very high quality photovoltaics and a tracking array and a power of 1000 suns is not unusual. High temperature is often what destroys equipment. Recent prototypes have captured the excess heat and attempt to use the Solar Thermal power in addition to the electrical potential.

Large Fresnel Lens Magnifier 8 x 10 Inches $7.99 This 8 x 10 inches magnifying plastic sheet is great for optics / science projects, for reading or just fun. A French physicist named Augustin Fresnel invented this lens in 1822 to be used in lighthouses. The construction of Fresnel lens is quite interesting as it allows magnification just like regular glass lenses do but it can be as thin as paper! This particular fresnel lens sheet is 2mm thick,… |
