Dye sensitized titania solar cell, especially useful for educational purposes, contains work and counter electrodes releasably coupled to each other

摘要

The counter-electrode (11) is releasably coupled to the work electrode (1), and both contain electrically conductive layers (2, 12) deposited on transparent substrates (4, 14). A dye-sensitized titania solar cell with a layered structure comprises a work electrode coupled to a counter-electrode via an electrolyte fluid. The work electrode comprises a first electrically conductive layer, a crystalline titania layer (3) on top of the conductive layer, and a dye-sensitized material deposited on top of the titania layer. The counter-electrode comprises a second electrically conductive layer with a catalyst material (16) deposited on top. At least one of the conductive layers is transparent and deposited on a transparent substrate. The titania layer is formed by drying and sintering a coating of paste material comprising titania powder, water, ethanol and acid. The counter-electrode is releasably coupled to the work electrode.
