OR one could insulate the back of the cell with a a very thin film (? can’t think of what) and then use direct water cooling on the back of cell surface it’s self.

OR even both sides of the cell……

Dans idea is quite a good idea…. it would be interesting to see just how far one could reliably push a 2V single 100ma cell (making that value up), through a solar concentrator and a form of liquid cooling.

Bingo – small and …
Bingo – small and cheap solar cell unit making stacks of power and free hot water without a solar water heater.

Not sure of the exact details in all of this in terms of electrical insulation on the underside of raw silicon solar cell slices (the qualification for the following statement); but one would need a thin film of silver based conductive heat sink compound to transfer the heat out of the cells, and into an aluminum heat sink with a water channel through it.

Cool Findings? No – …
Cool Findings? No – it’s an established fact – the HOTTER the solar cells get, the less efficient they get too (except for amphorous ones – up to a point).

The BEST way to radically increase the output of a solar cell (again up to a point) is to concentrate the light on it, and heat sink the solar cell to a cold resivour – like a “hot water tank” and heat the water in the tank from the heat sink, up to about 40 – 45*C

Cool findings… it would help if you did some more control testing… and realized that watching a dark display with a bright background on camera does not work well.

the electic eel ieda will not work and is very dangerous the reason it won’t work is because large amounts of electrity at a short rate cannot be harnessed 2-5 seconds the is the same reason as to why power station don’t have long electic poles with wires ontop to harness thunder which is about 45 kv that power will simple blow a fuse or been disposed of usually though earth wire hope this helped to clarfiy few things.

If that were the …
If that were the case, the voltage would have risen instantly. All solar panels and electrical devices work better when cool because of less resistance in the circuits.

I don’t think its’ because it’s cool. I think it’s because the water offers more reflection and more angles of light, and that offers MORE light at HIGHER doses. It’s like holding a mirror up to a solar panel. I don’t know if this is right, but I’ve seen this experiment done before with mirrors and water reflects light.

Dan,

Dan,
Thanks for all the great videos!! What type (brand) of solar panels are you using in this video??

Hi Dan & Denise, …
Hi Dan & Denise, not really related but I just read about an electric eel in Brazil that can produce 650 volts to stun prey and can stun a human.

Do you think it would be possible to keep on in a tank and harness its power? Or am I just being silly? It was just a small ‘did you know’ article and didn’t provide much more info, like how often it can shock in sequense. Would be good free power if it worked?

If it was the light tank, the voltage would have increased instantly vs slowly. Poly Cells, un like these cells have a metal backing so heat sinking would make sense. This was totally the cool water

In electronics, as …
In electronics, as circuit temperatures rise, circuit resistance also increases. Heat will decrease the output voltage. Most passive cooling systems will help to increase the voltage output. The only problem with the water solution is that once the water heats up, it will retain the heat longer. If you could circulate the water it will increase the cooling capacity greatly. I realy enjoy your vids. Great stuff and thanks for sharing.

is he… sure.. That the glass in teh tank wasn’t refracting more light toward the Cells? that would increase the voltage.. Same as replecting light from a mirror onto an already lit panel.. Or his fernel lense when he pointed it towards the cells.

I think that when …
I think that when distilled water is used instead of normal tap water, the results will be a little better because it is more clear. Also distilled water doesn’t conduct electricity …as far as I know…..so there is less danger of shorting out your solar panel.

I don’t have a solar panel, but I would love to see reactions from people that know more, or are willing to put up a test with distilled water and normal tap water to see if there is a difference in efficiency.

to other people:
- you don’t need a pump to circulate water, you just need a deeper tank with a radiator at the top, to use the convection effect: (hot water rises)

- using it to make hot water is not a really good idea, because you have to make a compromise between water temperature (higher the better) and solar panel temperature ( lower the better). it’s more efficient to have 2 different systems.
such a “hybrid system” would be good for pool heating because you don’t need high temperatures.

I think you could …
I think you could get an even higher voltage with the cooled panel because :
- part of the solar panel is shaded by the black edge of the water tank (5% shaded = 5% losses)

- the panel is not exactly facing the sun (because it didn’t fit in the tank, so you put it a bit side way)

- your water doesn’t look very clear on the video, maybe distillated water would be better

- you don’t need to have that much water in front of the panel, 2cm will be enough.

great video, keep up the good work

Interesting but you will get plenty of algae within a weeks so I would reconsider whether to use water in a transparent tank.
