home made solar cell

home made solar cell

Here is a low power low efficiency photovoltaic cell that you can make you own in the kitchen with materials from the hardware store.This cell is made from cuprous oxide instead of silicon and you can build a working solar cell in 2 hours to build it i follow this instruction.
Materials you will need
A sheet of copper flashing from the hardware store
A transparent CD case
Electric wire
Sodium bicarbonate or Table salt
An electric stove
hot glue
Sheet metal shears for cutting the copper
The first step is to cut a piece of the copper sheeting that is about the size of the burner on the stove.Next, place the cleaned and dried copper sheet on the burner and turn the burner to its highest setting.
Cook the copper for at least 30 min.
When the copper has cooled to room temperature (this takes about 20 minutes), most of the black oxide will be gone. A light scrubbing with your hands under running water will remove most of the small bits.
Cut another sheet of copper , Solder a wire to each copper plate,glue to insulate the soldering.
Seal the cell and fill it with a solution of baking soda (or cooking salt) and water.
Test the cell with Sunlight
