研究実績の概要 |
I have identified the key components to be used in the development of efficient multi-dye structure DSCs device. The parameters identified include: 1) Design of model UV-dyes, VIS-dyes and NIR-dyes for light harvesting a wide range of solar light, 2) Identify the dye uptake condition to form a monolayer coverage of multi-dye adsorbed TiO2 semiconductor by using selected additive/co-adsorbent. I have constructed a prototype two-dye structure DSCs device utilizing the results generated in Phase I-Task1 and 2. Initial performance evaluation of the two-dye structure DSCs device was performs in terms of: light harvesting efficiency (LHE) of novel UV-dyes and VIS-dyes, current-voltage characteristic (I-V) and incident photon-to-current conversion efficiency (IPCE) and few new design and synthesis of more efficient UV-dyes and VIS-dyes was identified.

Phase II. Synthesis/engineering and characterization of new IR-dyes and construction of prototype multi-dye structure DSCs. Task 1: Novel NIR-dyes with high molar extinction coefficient will be developed in this phase for an efficient multi-dye based co-sensitized DSCs device with minimum TiO2 film thickness. Task 2: The objective is to construct a prototype multi-dye structure DSCs device utilizing the results generated in Phase I and Phase 2(1). Multi-dye structure DSCs device will construct and performs initial performance evaluation in terms of: light harvesting efficiency (LHE) of novel dyes, current-voltage characteristic (I-V) and incident photon-to-current conversion efficiency (IPCE). Task 1: The objective is to optimize multi-dye structure DSCs device utilizing the results generated in Phase II specially new material develop in Phase II(2) and also using our high efficiency technology system and performs device performance evaluation.
