NOVELTY - The system has a plasmonic nanostructures integrated to a photoanode and a photocathode for enhancing respective electron and hole carrier transfer. The photoanode comprises a mesoporous n-type semiconducting material arranged on a transparent conductive substrate. The plasmonic nanostructures are integrated to the n-type semiconducting material acting as an electron acceptor material. A dye sensitizer acts as an electron donor material. The photocathode comprises a mesoporous p-type semiconducting material arranged on the transparent conductive substrate.    USE - Plasmonic enhanced tandem dye sensitized solar cell system.    ADVANTAGE - The system ensures charge oscillation results in plasmon polariton with reduced wavelength when the excitation is provided at a resonant frequency such that energy is confined in a plasmon mode as an intense field in the immediate vicinity of the antenna, so that the intense field efficiently couples to the electronic excitation of the dye molecules as the SERS effect, thus providing efficient pathway to electronically excite dye molecules from the incident radiation, and plasmonic enhancement aids to increase the efficiency of hole injection, and hence boosting the short-circuit current without impairing the photocathode open-circuit voltage and improving photocathode performance.    DETAILED DESCRIPTION - The n-type semiconducting material is an electron acceptor material that is made of n-type semiconducting metal oxide selected from a group consisting of titanium oxide, zinc oxide, tungsten oxide and molybdenum oxide. The electron donor material is made of metal complex selected from a group including ruthenium, osmium, rhenium, platinum, iron and copper, and porphyrins, chlorophylls, phthalocyanines, and organic dyes selected from a group including coumarin dyes, indoline dyes, tetrahydroquinoline dyes, triarylamine dyes, heteroanthracene dyes, carbazole dyes, N,N-dialkylaniline dyes, hemicyanine dyes, merocyanine dyes, squaraine dyes, perylene dyes, anthraquinone dyes, boradiazaindacene dyes, oligothiophene dyes and polymeric dyes. An INDEPENDENT CLAIM is also included for a method for manufacturing plasmonic nanostructure in a plasmonic enhanced tandem dye sensitized solar cell system.
