Marion King Hubbert came up with the peak oil theory back in the 1950's. He predicted American oil production would peak about 1970 and then enter a never ending decline. He also understood that solar voltaic panels could be made to produce more.

I don't know what exactly needs to be done to make panels more sensitive and produce more current but I have some ideas. One is to put more PN junctions per square inch and the other is to use power components. Another is to mix atomic sized particles in the semiconductor to stop the light from reflecting.

Why would oil companies allow someone to make a solar panel that would put them out of business? They probably wouldn't. Oil companies run everything and it's a good ole boy network. I think they have known for decades how to make solar voltaic panels produce more current and make them useful all year long. I can't prove this. I'm paranoid from years of illegal surveillance. Anyway. When they first began making integrated circuits (IC's) someone predicted the number of transistors per square inch would double every 18 months. That was the early 1960's. Today an Intel Core i3 has billions of transistors on a single chip about 1 inch square. Have they ever applied this technology to making solar voltaic panels? Would packing billions of PN junctions per square inch make them more sensitive and produce more current? I don't know.

Maybe going the opposite direction is the answer. Below is a picture of a photo diode big enough to work with by hand. It is a Wurth Electronics WL-SDCB. I think it's possible to make a solar voltaic panel out of these to investigate whether it would produce more current than a small PN junction. The next picture is a schematic. There are multiple rows of diodes in parallel connected in series. Instead of trying to produce DC current I think it would be better to produce AC (varying). You could do this by covering the entire assembly with an liquid crystal display (LCD), sometimes called electrochromic glass or smart glass, and pulse it on and off with control circuitry from the opposite side of a transformer. If you could produce enough voltage and current the entire assembly would run any off the shelf ac device without an inverter. This lowers cost complexity and increases flexibility. You make the panel so sensitive it would burn up on a very sunny day. The smart glass would adjust and this would make the panel useable on cloudy days.

A serious problem with voltaic panels is snow. I think you could embed wire in the glass that covers the assembly and heat it up with current. This will melt snow as it falls. It works much like an automobile rear window de-fogger.

If the diode above doesn't produce enough current I have an ideas. You could embed atomic sized glass particles in the semiconductor and they would help trap the light and 'bounce it around'.
