Key technological elements in dye-sensitized solar cells (DSC)

Abstract

The best cell efficiency of lab scale dye sensitized solar cell (DSC) exceeds 11%, but there are still many technological problems to overcome for commercialization. This review describes key technological elements in DSC, including working electrodes with dye/TiO 2 /electrolyte interfaces, quasi solid state electrolyte with ion diffusion, and counter electrodes with electrolyte-catalytic electrode interfaces. Their operating principles, equivalent electric circuits and measurement techniques are described.

Improved Light Conversion Efficiency Of Dye-Sensitized Solar Cell By Dispersing Submicron-Sized Granules Into The Nano-Sized TiO2 Layer

“…Dye-sensitized solar cells (DSSCs) are considered as one of the potential solar cells due to their low fabrication cost and simple structure compared with conventional silicon solar cells [1][2]. The light-conversion efficiency of DSSCs, however, is low and needed to be increased for successful commercialization.…”

Electrochemical properties of poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) and carbon black composite as an electron injector into the electrolyte containing iodide redox couple

“…Dye-sensitized solar cells (DSCs) have received considerable attention as a next generation photovoltaic device due to their high photovoltaic conversion efficiency ($12%), low cost and easy fabrication process [1][2][3]. Most DSCs are made of a dye-sensitized nanoporous TiO 2 film on the fluorine-doped tin oxide (FTO glass) as a photoanode, a liquid electrolyte containing iodide/triiodide (I À /I 3 À ) redox couple, and a counter electrode.…”

Improvement of Light-Harvesting Efficiency of TiO2Granules Through Chemical Interconnection of Nanoparticles by Adding TEOT to Spray Solution

“…Dye-sensitized solar cells (DSSCs) are considered excellent photovoltaic devices which can convert the solar energy into the electricity because they have simple structure, low production cost and large flexibility of colors and shapes [1][2][3][4]. Since the first demonstration of dye-sensitized solar cells by Grätzel and co-workers in 1991, there have been many efforts to improve the solar-to-electric power-conversion efficiency (PCE) of DSSCs.…”
