Progress in light harvesting and charge injection of dye-sensitized solar cells

JK Lee, M Yang - Materials Science and Engineering: B, 2011 - Elsevier
Dye-sensitized solar cells (DSSCs) based on nanocrystalline semiconductors such as TiO2
are of great interest as an alternative to the conventional solar cells because of their high
performance, low-cost production, and environmental advantages. The DSSCs consist of
dye molecule coated wide bandgap semiconductor layer, electrolyte, and transparent
conducting oxide (TCO) film. When the DSSCs are exposed to solar light, an incident photon
creates a bound electron–hole pair in dye sensitizers. Electrons then flow into the oxide …
