Abstract:
The first generation of dye-sensitized solar cell technology is based on a liquid electrolyte component. Today, this technology is on the verge of commercialization. The step towards the market and real applications is supported by the prospect low manufacturing costs, good efficiency as well as the expectation that the current stability level of this technology is at least sufficient for applications in mobile electronics. These favorable developments may be reinforced and accelerated even further, if the corrosive liquid electrolyte could be replaced by a non-corrosive solid, since this would ease a number of stringent requirements in the production process. A successful exchange of the liquid electrolyte by a solid-state holeconductor requires to at least maintain, preferably improve, the most relevant technical parameters of the solar cell (efficiency, stability, cost). First pioneering work with solid-state holeconductors was carried out 10 years ago with an initial efficiency level below 1%. Until 2007, the record efficiency could be improved to 5%. This paper gives an overview of the solid-state concept as an early stage approach with good perspectives for the mid-term future (~ 5-10 years).
