Lasersaber strikes again. A joule thief king ?

You are absolutely right, Infra Red (IR) solar panel don't work,
and it  will not work also when you try something weird, right ?

Welcome to the  forgotten technology..

Hi Marsing,

Any PN material that are exposed to light will generate a voltage (and current).
This is also true for IR LEDs that have a clear plastic case. I have tested the
LED panel in total darkness. No output voltage. Then switch on a 940nM IR
light, and voila, the panel has output voltage. It is not weird at all.

I did design 10 of those IR LED panels back in 2007. Was planning to use
them as IR light for a CCD camera. But now you can buy IR flood lights
for that usage that are water proof.

You can probably buy 1000 of those 3mm IR LEDs today, at around US 60$ on the net.

Hi folks, Hi groundloop, thanks for sharing.
Could you share what kind of current and voltage output you're getting with your infrared led panel in the sun and indoor light, when charging your AA cell, thanks.
Also, what do those infrared leds cost.
peace love light

SkyWatcher,

The output voltage in indoor light is approx. 2,8 Volt. The current is very low, typical some few uA.
You can probably find somewhere to buy those LEDs on the net. See above post.

here is another ongoing effort from Slyder

thx

Thanks, Chet.  Good work, Slider.  I like the test where you put the device inside a u-wave oven and it still runs, while a radio won't run inside.  But would like to know how LONG it runs inside versus outside.  IOW, does putting in the cage make any difference?  wasn't clear to me...

Hi groundloop, actually i think about your name. LoL

Yes Transistor 2N3055 will do too,  this  from youtube ( i am  not sure about output).

Marsing,

I was a member of a Radio Control flying club when I first did choose my Internet name.
We did a lot of groundloops back then. :-) Also, I have seen a lot of groundloops when
designing audio amplifiers and such. :-)

Yes, if you cut the top of a TO-3 transistor (or diode) then you can use the die as a NP solar collector.

One thing I was wondering about is why the designers of solar panels do not combine those
panels to also heat water. And, the panels should have a Fresnel lens on top so that the orientation
of the panels does not matter that much. So, three layers, first the Fresnel lens layer, then the NP layer
and last the water layer. Or does that already exist?
