Blu ray discs pretty color actually makes them great at capturing light.
Make a solar cell from a cd.
I mean how on earth can you build a solar panel using shiny old plastic disks.
To make a solar cell you ll need 2 glass plates transparent tape and a titanium dioxide solution.
It may take longer for larger batteries such as those used for large flashlights or batteries in which case a solar cell that has a trickle charger is ideal.
A 20 watt solar panel can reduce your recharging time to just a few hours for aaa aa c and d batteries.
It sounds relatively implausible i know.
The other plate should be coated with carbon.
How to make extra efficient solar panels using old blu ray discs.
Once the coatings are complete place the carbon.
How to make a solar panel using your old metallica cd collection boot legs included.
If the cell made here had maybe an aluminum cathode or a graphite cathode the system would most likely function much better becoming much more active with the heat to make a much more reactive galvnic battery charge output however photons don t seem to be functioning in this cell as in a real solar cell due to the fact that the copper.
First you ll need to clean both plates with alcohol.
Then bake a titanium dioxide coating onto 1 of the plates before soaking it in a red dye.
