Liquid Dye-Sensitized Solar Cells

Abstract

Dye-sensitized solar cells represent a type of device which converts solar energy into electricity based on molecular components. This is an attractive alternative for solar energy conversion because such devices can be made as low-cost, colorful, and transparent solar cell in contrast to the traditional semiconductor-based solar cells. In this chapter, we will give an overview of all molecule-based components in this kind of solar cell and also comment on its working principle, the dye design, the dye arrangement, the electrolyte composition, as well as the counter electrode materials. The standard types of dye-sensitized solar cells are regarded as n-type, but at the end, p-type and tandem dye-sensitized solar cells will also be introduced.
