This article describes the design and operation of a dye sensitized solar cell with an all carbon counter electrode plastic electrolyte. For construction electrode, conventional thin platinum catalytic layer was replaced by novel large-effective-surface-area polyaromatic hydrocarbon (LPAH) film, fluorine doped tin oxide substrate graphite film. In this way internal resistance substantially reduced efficiency can reach nearly 9% using masked frame measurement technique. To achieve such efficiency, series experiments carried out to assure that LPAH possesses superior activity energy compared commonly used black. end unique synthesis technique developed. It involved production from hydrogen arc along use amphiphilic triblock copolymer (P123) improve suspendability form homogeneous layer. then attached film for cell. Details properties LAPH newly designed are reported herein.
