Finally : cheap DIY selfmade solar cell with common materials !
« on: January 31, 2009, 05:38:38 AM »
Hi ALL,
I guess this is a real breaktrough in solar energy
as now a selfmade process to produce cheap solar cells has
been posted on Youtube.

Have a look at this:

Okay, I just received the info how to build it from Matt:

He said:


things required
strong thin knife,glass cutter,Titanium dioxide,LCD panel,silver conducting varnish,methylated spirits,
distilled water,plant dye,sealant glue,source of iodide/iodine,candle.

be very wary when disassembling LCD screens-the potential for cuts is always present.
handle with cloth covers when prying open-use eye protection.

disclaimer-dont try this at home if your a fool and likely to hurt yourself.


1.disassemble an LCD panel.
use a stanley knife to remove glue from plate edges.
run cuts across the plastic film coating to allow the introduction of methyted spirits
to breakdown the glue holding the plastic film coating.
remove the plastic film from both sides.
check the egdes have been thouroughly roughed up and any excess epoxy like glue on the edges of the
LCD panel.you can try your luck with some sort of solvent to loosen up the panels,but i just scored the panel right the middle with a glass cutter,both sides,and started to pry the edges open.was going really well until cracked it-luckily the crack followed the glass cut line,and eventually i had the 2 faces of the panel appart although it was broken in a few a places.remove the plastic film from the inside of the panel after washing the liquid crystal goo off trim up the pieces with the glass cutter,so you have to pieces the same size.

2.clean the trimmed pieces with methylated spirits,to remove all traces of adhesive.
paint tracks of conductive silver across the face of the Tin Oxide side of the glass.
take the collective bunch of tracks to one edge of the plate,this is where you will attach you terminals.

3.prepare the Titanium Dioxide with 50/50 distilled water ,and methylated spirits.
stir it up and use the fine stuff of the top after settling to apply to the plates.

4.apply the Tio2 suspension onto the plates.allow to dry heat dry if available-i used a heat gun.
5.prepare the dye by mashing with methylated spirits,and squeeze thru fine cloth onto only one plate.allow it to settle into the Tio2 layer.wash with distilled water.
allow to dry-heat dry if possible.

6.prepare a candle with a long flame.quickly run the plate that has no dye on it over the flame,to deposit carbon onto the plate.wash with distilled water allow to dry-heat dry if possible

7.by this stage you have 2 plates-one with Tio2 and dye-one with Tio2 and carbon.
thouroughly clean the edges to prepare for the sealing glue-i used methylated spirits.
8.run a bead of the egde sealing glue around one plate,leaving a small gap at one corner for the excess electrolyte to run out when.this will help in sealing it without any bubbles inside.
9.i mixed betadine antiseptic solution(which contains povidone iodine 12%) with methylated spirits-80:20
10.pour some electrolyte onto the plate and place the other plate on top,tilting it slightly so that the corner that is the opposite corner to the gap in the sealant.
place the top plate down so that you can pick it up tilt it slightly so the air gap can be squeezed out the top corner.put sealant over the corner gap.

remember to leave a slight overlap and have the terminals at opposite ends.

regards

this is my first attempt -so i dont know what would happen without the berry juice.
i was just following the description of the TiO2 dye cell to begin with.
and see where it went.
im thinking of trying copper and silver instead of TiO2 and ITO ,and using chlrophyll,but these are down the road-this is just the beginning.
feel free to spread these ideas ,and encourage others to to have a go!

many regards

matt

I replied:

Hi Matt,
Well,
you really have to find a semiconductor PN-layer to get this to work.
So there must be the right bandgap for to convert the electronVolts
of the sunlight to push electrons through this diode-bandgap...

So with just 2 metals like silver and copper you mighthave a totally wrong
bandgap and you just only create a galvanic cell, where the metals are used up
with the electrolyte.

In a solar cell the trick is to have the right bandgap PN-layer for the sunlight
and not to use up the electrodes in the process..

Hi Matt,

why did you put TIO2 onto the plate with the graphite from the candle ?

Normally you need only one ITO-TIO2 PN-layer and the other glas
must only have graphite as the other electrode.

The silver is okay to collect the electron current from the graphite,
so you just could use a silver painted glas or plastic plate
where you would have put the graphite onto the silver.

So you could spare one ITO coated glasplate.

The sunlight conversion just only happens between
the ITO-TIO2 surface layer that is exposed to sunlight.
The smaller this layer is, the better the conversion,
so just try to make this very thin, just a few mikrometer.

So it was a good idea to burn the TIO2 into the ITO with
a hot gun.


Regards, Stefan.

Re: Re: Re:solar panel LCD recycle
>why did i put the TiO2 on the other side too?

because i made a mistake

thanx for bringing that to my attention.
i didnt notice that when i looked it over.

maybe that will give better results now.


thanx agsain

Here are 2 very bight researchers, who have got also very good results
with their own build Graetzel cells and their own modified cells:

http://www.jufo-mbs.de/pageID_4302252.html

Also check their other pages and their youtube videos:

http://www.jufo-mbs.de/pageID_4244942.html
They also have developed a new lacto bacteria based fuel
cell without Platinum !

Forgive me for butting in here but I built a nice little panel this Sunday with some small cells 16+ volts output...

But I have been following this thread a little and I have most of the goods to manufacture homemade.

I do unfortunately have a snag or two...

Do you think arctic silver thermal compound will work for the "Silver Varnish" as he calls it? Arctic silver 5 is like 95% silver if my memory serves me correctly.

Finally for dye is there anything other then squeezing dye out of fruits and leaves that I can do to get my reddish dye needed is there say a dye that is artificial or a particular fruit juice I can use like welches grape or something?

The other thing that has me going is will adding a layer of piezoelectric material such as rochell salt be helpful I have always wondered how piezoelectric materials may be able to add gains to solar you would thing from the heat differences that the cells may flex from time to time thus giving off electricity in minute amounts....

Any thoughts or takers?

That looks like a good hack  8)

Does the substrate have to be LCD screen, or can you use ordinary plate glass ?.

You know I'm not 100% sure to tell the truth I would imagine you could use nearly anything that light can pass through but I could be wrong I am no chemist but I'm curious if lexan would work as well...  I will likely do some testing I have 2 15" LCD monitors but I am aiming to make a cell with the full size of the screen. Beyond that its all testing but the stuff is pretty available to make this ...

Ti02 is on its way along with the arctic silver...

By the way denatured alcohol is what you need in the US not methylated spirits ...

Anyhow very interesting project.

Hrmmm...

Either I'm a bad thread edition or ... There is a huge lack of interest in solar...

I thought someone might have tested the effects of piezoelectric in the sun to see if there were small gains it really has me wondering if I couldn't make a cell out of melted rochell salt... well obviously you will need dye and such to catch the light but it may be doable either as the substrate in place of silicone or as an additive.

There must be a lack of interest from day one. How can it be, that we get as far as we have with technology, and most scientists an especially the world leaders, have completely ignored that big ball of energy all these years ?

They have also ignored something else too. That big ball of rock that we call the moon. Surely the effects of that thing circling our planet could be harnessed somehow !

Doug thank you much for jumping in and contributing something to the thread.

Bulbz always a pleasure man I look forward to your posts they are always positively charged ;)

I will have to do some digging and testing I wanna buy a heat gun and such. I have about 6 soldering irons and such for other projects I need a good heat gun or hot air station for SMT would even be better but either way there is a lot untested and simply not tried in life ...

And the efficiency could definitely be better on conversion ... We all know it can be improved.

Finally we all know that we can make these cells for pennies on the dollar somehow if we all worked to this in a group imagine what could come out of it... Home solar panels capable of professional production results...

Very possible but I feel people are scared and it does not take much at all scrap stuff and a little common chemicals...

Why do we not look at this I know the pie in the sky is fun to chase but really why don't we use known methods to produce results we all look for ? Near free energy...

Where is everyone on this all the experts of energy ... The admin took his time out to create this great post and share this great knowledge with us and we simply choose to ignore it because it doesn't have a coil or a magnet and we all already know it works...

Well I say hook your coils and magnets up to the sun ... Do all the testing you need with free power already available...

Anyhow enough ranting.
