Selfmade Solarcell from copper-1-oxide with ionic liquid ! DIY Solarcells

Yes, but with all the no-hopers posting rubbish videos around, nobody in their right mind would be bothered to replicate unless advised as to what that number is, and whether it is worth the trouble.

well, i can say this, a 1 watt solar cell would be small compared to the 4.5watt 6"x6" one, there would be more solder work accordingly.
and the solder is silver based making it more expensive than the other kinds of solder.

also there is usually the concern about moisture degrading the cell if it finds any, so it needs to be sealed completely.
and not just using anything, but something that will not break down from UV, or prevent much UV from reaching the cell.
that clear sealant is usually in a A&B formula that has to be mixed properly, and then theres air bubbles that will form in the curing process, unless you have a vibration table to sit the curing panel on until its ready.
plus that sealant is rather overpriced.
there is a much cheaper option for sealant i am considering that is from Black Knight, they sell it in black, white, and clear,designed  for coating roofs. regular silicon just is not good enough even though it says waterproof. it will still let cell degrasion to occur being just silicon.

there is another option to sealing the panels that is fast and with no VOC's during the curing process that the other sealants create,
that other option is a type of clear uv protected shrinkwrap. the wrap is more affordable, though you need a heatgun and a bit of practice maybe.

you will also want a inline diode to help protect the cell from trying to charge itself from the battery, or it could become time to void the home insurance policy, actually if its not UL approved and gets installed, the policy is probably voided as a result, plus maybe proof of a licensed electrician to complete all the connections, though you might just be tickering around avoiding the need for much more than a charge controller and the inline per panel diode, unless the panel is less than half of what the diode is rated for, then you can throw 2 panels inline towards it.

you do not want to use wood for framing the panel. and plexiglass can haze unless its that overpriced stuff, also cracks could form if hail hits it, or falling piece of airplane material, ufo etc. plus you have to keep wiping off the snot from spidermans gloves, if hes in your area.

i suppose if you are just keeping the cell or panel indoors, and it isnt getting any moisture from being near the window, you could get away with that for a while.

as for making a panel using cuperous oxide from heated copper, that is rather inefficient compared to the other stuff, mono, poly and unicrystaline or omni or some other word i can't remember right now, but essentially the most powerful one of the 3 would be uni, being that it can absorb useable light from a greater angle rather than being directly facing the sun. and its can also still work under a pile of snow though to reduced production of power.

depending on what you need the power for, theres also passive solar to consider.

theres other thin film versions of solar, even graphene i think has use here.

a solar based paint would be great. as being 4 layers of different material to become functioning. <protective outer layer, the + and the - coatings, and the insulator coating that separates them. not such a thing is being sold yet, though i have been wrong before, and will continue to be wrong sometimes sometimes just because its not always easy to accept change.
