A design for monolithic all-solid-state dye-sensitized solar cells with a platinized carbon counterelectrode

The high cost of electricity produced by solar cells compared to electricity from other energy sources is an inhibitor to a more widespread adoption of solar energy. Here a low-cost monolithic all-solid-state dye-sensitized solar cell (DSSC) was developed with a platinized carbon counterelectrode. The vacuum pore-filling technique proved to be effective for uniform infiltration of polymer nanocomposite electrolytes into the multilayer thick films. This monolithic design will be used for other solid-state or quasisolid electrolyte material-based DSSC, which allows for the development of stable and low-cost solar cells.
