Three-dimensional Transparent Conducting Oxide Based Dye Sensitized Solar Cells

Electron transport and recombination are two competing factors within Dye-Sensitized Solar-Cells (DSSCs) which have a great influence on their performance. By drastically increasing the speed of electron transport to the electrode, it is believed that these cells could reach new record efficiencies. To achieve this result, an all-in-one integrated DSSC was attempted, in which the electrode material is extended into the active area of the solar cell material. The research conducted can be separated into two stages. The first stage is the production of a three-dimensional macroporous electrode. The second stage is the production of an all-in-one DSSC by a simplified co-casting technique. The structures and materials presented were examined using electron microscopy, X-ray Diffraction, 4-point and 2-point probe electrical measurements as well as experimentally by the testing of solar cells. The methods of fabrication, characterization, experimental results and future directions are also presented.MAS
