This chapter aims to review the DSSC-device. For more than 16 years, dye sensitized solar cells (DSSC) have been under extensive research. Since the color of the device can be easily varied by choosing different dyes and cells on flexible substrates have been already demonstrated, DSSCs are especially attractive for Building Integrated Photovoltaics (BIPV).

The cell concept is believed  to reduce the production costs and energy payback time significantly compared to standard  silicon cells or other thin film cells. The  conversion efficiency varies between  6-10% depending on the module size and the technology is currently on the pilot plant scale.

In chapter 2.1 the operation principle of the cell is outlined, starting with a brief abstract of the device's history. 

Chapter 2.2   discusses current efforts to optimize the cell. First  the main impediments for large-scale production are presented and then different approaches to improve the
hole conduction in the electrolyte and the light harvesting of the dye are introduced.

Chapter 2.2.2 reviews the standard iodine-based electrolyte, which gives the highest efficiency at the moment. But since iodine corrodes most metals and makes the upscaling of the device difficult, a lot of research is done of alternative hole conductors.  Some examples are discussed  in chapter
2.2.3.

In chapter 2.2.4, it is tried to give an overview on the large variety of different dyes that are capable to inject electrons in to wide band gap semiconductors like titanium dioxide. The chapter
closes with a preliminary feasibility study of DSSC production  on the 1 MW scale. The price per W
P for each cell component is estimated and the availability of ruthenium as an integralpart of the  sensitizer is critically discussed.
