Photovoltaic properties and preparations of dye-sensitized solar cells using solid-state polymer electrolytes
Solid-state dye-sensitized solar cells were fabricated using a polymer matrix in polymer electrolyte in the purpose of the improvement of the durability in the dye-sensitized solar cells. In these dye-sensitized solar cells, the polymer electrolyte consisting of I-2 , LiI, ionic liquid, ethylene carbonate/propylene carbonate (EC/PC) and polymer matrix was casted onto TiO2 electrode impregnated Ruthenium dye as a photosensitizer. Photovoltaic properties of dye-sensitized solar cells using polymer matrix (PMMA, PEG, or PAN) in solid-state polymer electrolytes were investigated. Comparing photovoltaic effects of cells using hole conducting polymers (BE or 6P) instead of polymer matrix, we have investigated the availability of the solid-state polymer electrolyte in dye-sensitized solar cells.
