Monolithic all-solid-state dye-sensitized solar cells

As a low-cost photovoltaic technology, dyesensitized solar cell (DSSC) has attracted widespread attention in the past decade. During its development to commercial application, decreasing the production cost and increasing the device stability take the most importance. Compared with conventional sandwich structure liquid-state DSSCs, monolithic all-solid-state mesoscopic solar cells based on mesoscopic carbon counter electrodes and solid-state electrolytes present much lower production cost and provide a prospect of long-term stability. This review presents the recent progress of materials and achievement for all-solid-state DSSCs. In particular, representative examples are highlighted with the results of our monolithic all-solid-state mesoscopic solar cell devices and modules.
