Development of solid polymeric electrolyte for DSSC device

We fabricated TiO₂/N719 dye/PVB base solid state electrolyte DSSC which with efficiency 3.75% in average that can be further optimized and the best efficiency we achieved is 5.20%. To optimize the performance of a solid state DSSC device, the work we have done including the relation between PVB immersed time and the ion conductivity of ion PVB, the incident photon-to-current efficiency (IPCE) test of the PVB base DSSC, and the long-term stability test. This is the first attempt to combine the worldwide used material, PVB, and dye-sensitized solar cell successfully. With the work other groups done before, we can increase the capabilities and values of smart windows with no doubt.
