First off solid state light detector diodes (whatever the band of light they are sensitive to) do not generate electricity they improve their conductivity (reduce their voltage drop "losses" in rectification mode, their "base to collector" resistance lowers or "conductivity" improves) when their third virtual "emitter" (light exposure) is present. You must pass a current through them for them to "see", they are not photovoltaic "batteries".

A photovoltaic solar cell on the other hand converts light energy (or the heat that it produces) into electrical energy. Solar photovoltaic cells manufactured in broad, flat panels (or as surface coating layers) always have a much larger surface area than a single p/n junction, but a common lens (other than the Fresnel sort) only focusses a light source upon one single spot. A spherical lens is only efficient on one single axis and focal point of operation and a Fresnel is a much less efficient "wide diffuser" more than it is single, focal-area lens.

To use a spherical or Fresnel (onion-ringed) type of lens on a solar panel one must have some powered articulated means of automatically focussing and tracking the light source, lens and panel to it. In a solar application both the lens over a photovoltaic solar cell array and the array itself, and (to some extent) the distance between them must be continually adjusted to the sun.

Unfortunately using any sort of a lens with sunlight causes one a HUGE DESTRUCTIVE PROBLEM - "big, big heat" which is totally incompatible with most solid state semiconductors and most photovoltaic solar cells and even voltaic thermocouples.

Motorized parabolic or concentric mirrors focussed on circulated oil-type coolant tubing heat exchanger steam powerplants have already been built to use out in deserts to take advantage of such techniques. Unfortunately these methods don't work for stationary solar panels, or rooftop water tubes, because moving the things (with motors and controllers) causes power losses (generally) not made up for by the amount of power that smaller photovoltaics can produce, and serious reliability/maintenance issues in cold climates though there is an example of such an advanced single-axis only system at Nellis AFB out in the desert. that uses no parabolic-lens mirrors nor "lenses"

Thanks for your informative post... I'm thinking outside of the box to have a stationary lens with many facets so when the sun changes it's course then the suns ray will align with those set angled facets at different times of the day. Does that seems plausible?

Maybe something like a huge fish-eye lens (rather expensive) might work wonders for a small stationary solar panel but you'd still have to deal with the on axis heat at noon.

An infrared detector like the guy showed in his video can have a lens like a LED does so it can see the little light beam from the irLED (or a reflection of it off something shiny nearby) in your remote control in a bright room because heat isn't an issue. If you leave your digital camera lying uncapped out in the sun too long you'll come across that problem, though!

Camera arrays are not photovoltaics, they are really just "static" two-dimensional RAM chip bit-cell "detector" arrays that are photo"sensitive". Their individual bit-array states are polled and then read-out as "stored" transient "image data" from moment to moment, there are a variety of different (usually layered or cell-matrix) means to make them to be color discriminating.

ANY lens (coated or not) actually reduces overall optical energy bandwidth because the "transparent" materials absorb (or refract at different propagation rates and angles - the prismatic effect) certain light frequencies more than others, in addition, a lens is actually more of a filter where it is not focussing. A (usually parabolic) mirror is the much better alternative always used in astronomy for the most efficient "collection" of broadband light.

The Parabolic Trough collector and Solar Power Tower collector systems are the best examples of "lensed" collection today, but the very advanced Nellis solar tracking example clearly demonstrates that current photovoltaic technologies are not compatible with this sort of a "lensed/tracking light amplification" concept.

The problem with photovoltaics is that they have an energy conversion "peak", once you pass this point of maximum thermal and/or conversion efficiency you stop getting more energy out and start destroying the converter's chemistry with heat.

Even taking too much energy out too fast (shorting the panel) under optimal lighting conditions produces more, destructive, heat.

I don't know the level of the science to that degree, but that's about right agent.

Modifying solar panels has been an ongoing effort in the industry, and they all have to deal with the same issue; maintainiung optimum amount of light ontot he surface for the longest perod of time to maximize the amount of energy the cells can produce. The issue involve angle of light in relation to the position of the solar cell surface. Science trys to improve that by taking advantage of the fact that light bounces of stuff, and changes direction when going through stuff, so they came up with things like mirrors and prisms to direct light in the direction they want it, but when your source is a moving target like the sun, your prism or whatever surface you want light to shine on must adjust with the movement of the sun.

The idea of having multiple lens for the light to shine through for direction and amplification of instensity has been tried all kinds of ways, and it all is centered on being as close to the cell itself as possible so you have a very small lens area directly at the cell which in turn requires a very small lens. Kind of like why have eyeglasses that are the diameter of dinner plates when all you really need is some about the size of your eyes, so long as they are at the proper distance from the eyes themselves. What is that focul length? Not sure, but that's the idea.

A Fresnel lens is a pretty neat concept. A lens on steriods. I've seen sunlight through a fresnel melt metal in seconds. EXTREME heat can be generated, so long as you maintain the proper alignment with the sun and the lens and on the target. You get a little off and the intensity drops massively. Got to keep it focused for it to really work, but it works real well.

You not only have to factor the east/west movement, you have to factor the movement seasonally to. Winter sun doesn't rise as high, but it's not like a sudden change. It happens over the whole year, so technically you would have to be adjusting your panels year-round 24 hours a day.
