| Outline of Annual Research Achievements |
During last two years, I have design and synthesized few potential new dyes covering a short and a long wavelength light based on metal complexes and metal-free organic dyes. Multi-dye sensitized DSCs device with these novel new dyes were constructed and performed 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). Based on the above feedback for proper matching of UV, VIS and NIR light harvesting of dyes, new design and synthesis of more efficient dyes are going on to construct efficient DSCs device and conduction band energies of nanocrystalline metal oxide. The research results are presented at two international scientific meetings and also published in seven peer reviewed scientific journals.

Phase III: Optimization of multi-dye based DSCs performance, summarized the factors that govern the efficiency of the device and proposals for future research directions
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.
Task 2: Different optical and electrical investigation will employ to understand inside the interfacial charge transfer dynamics.
Task 3: The proposed multi-dye structure DSCs device will be further optimized to minimize the detected losses in Phase III (2). The key findings and the excellent results of this research will be patented and published.
Task 4: Summarized the factors that govern the efficiency of the device and proposals for future research directions.
