4.2.4.2 Quantum Dot Sensitized Solar Cells (QDSSCs)

Similar to DSSCs, Quantum Dot Sensitized Solar Cells (QDSSCs) consist of a QD sensitized photoelectrode and a counter electrode separated by a liquid electrolyte, as presented in Fig. 4.13. In general, wide bandgap metal oxide (TiO, ZnO, and SnO; in the following TiO is used as an example) nanostructures (e.g. nanoparticulate, nanorods, nanowires, nanotubes, and inverse opal) are used as the photoelectrodes in QDSSCs. QDs can be deposited on the photoelectrodes by two kinds of in-situ growth methods, i.e. chemical bath deposition and successive ionic layer absorption and reaction, and by adsorption of pre-synthesized QDs through direct adsorption or linker-assisted QD deposition method [35–37]. A number of QDs, such as CdS, CdSe, CdTe, PbS, SbS, CuInS, CdSeTe, CuInSeS and core-shell structure or double layered QDs, such as CdSe/CdTe, ZnTe/CdSe, CdS/CdSe, PbS/CdS, have been applied as sensitizers in QDSSCs [35]. Aqueous polysulfide solution is most widely used as the electrolyte for QDSSCs. Some solid-state hole transport materials (HTMs), such as P3HT, Spiro-OMeTAD, and CuSCN, are also used as hole scavenging and transport layers in QDSSCs [38, 39]. For the polysulfide electrolyte, copper sulfide (CuS) is the most used counter electrode. For the solid-state HTMs, gold and silver are commonly used as electrodes.
