Description

In recent years, most of the countries are managing to pursue clean andrenewable energy sources to fulfill the world energy demands without harmingthe environment. One of such green energies that gained great attention is thephotovoltaic (PV) technology, which converts solar-to-electric energy. The firstrepresentative for PV technology as a commercial product is silicon-based PV,which holds its ground for clean electricity production. Although having suchincreasing importance, there are still some challenging setbacks such as makingeconomically liable PV power grids and enabling large scale production whichneed to be addressed. Another uprising solar energy harvesting devices, such asperovskite solar cells (PSCs) and hybrid organic-inorganic dye sensitized solarcells (DSSCs), have paved to be new alternative PV technologies. These devicesare inexpensive, have tunable properties, and can deliver respectful photoconversion efficiencies. One of the main components that contributes for theexcellent performance of PSC and DSSC is the hole transporting material (HTM)and dye sensitizer, respectively. Therefore, we focus our works on advancementof these types of materials based on the following sequences: 1) Explore newand unique small organic molecules that can be synthesized with low cost anduse them as efficient HTMs and novel sensitizers in PSCs and DSSCs. 2) Focuson the design strategies of these materials to further achieve enhanced efficiencyand great stability of PV cells; 3) Fine tuning of material configuration orcomposition and the device architecture to optimize overall cell performance.Our current research involves the discovery and development of efficientphotoelectric materials with excellent chemical stabilities while focusing on greenchemistry of solar cells. The key goal of this proposal is to discover unique photovoltaic materials for PSCs and DSSCs applications and specific targets areas the followings: 1) Rational design of HTMs for PSC applications based onmetal complexes, donor-donor, and donor-acceptor-donor configurations; 2)Utilization of new approaches to synthesize efficient HTMs with hydrophilicnature, unique salt-based and metal complexed HTMs especially, that can helpto improve the formation of perovskite in PSCs; 3) Screening of various metalsexperimentally using hybrid designs to achieve new ruthenium free organicmetal-hybrid sensitizers that can lift the performance for DSSCs; 4) Evaluation ofpower conversion efficiencies and other photoelectric properties of PSCs andDSSCs based on synthesized novel photovoltaic materials; 5) Investigation ofnecessary structure modifications based on the analysis of the resulting data andthe corresponding device interfacial mechanisms to create next generation ofpatentable photoelectric materials for PSCs and DSSCs with marketablepotential.
