Quantum dots (QDs) have been utilized as light harvesting assemblies on photoanodes for applications in quantum dot sensitized solar cells. QDs are bound (sensitized) to a titanium dioxide surface using the bifunctional linker molecule 3-mercaptopropionic acid. The cadmium selenide QDs are synthesiz...
