Building the Solar Cell requires a
conductive glass plate which has been coated with Titanium
Dioxide (TiO).
Teachers may perform the coating of the glass plates, using
the procedures described in the references at the end of this
page.
Depositing the nanocrystalline TiO
film requires the preparation of a solution containing commercial
colloidal TiO
powder, the masking of a cleaned conductive glass plate, and
the application and distribution of the solution on the conductive
glass plate, followed by the sintering of the resulting thin
film layer. The following photographs illustrate the steps
in this procedure.
