Project Details

Description

Energy has always played an essential role in human and economic development and insociety’s well-being. The growth rate of energy demand has been dramatically upraised withincreasing world’s population and their urbanization. Whereas the rapid depletion of fossilfuels poses serious environmental issues which demand for the clean and renewable energytechnologies. Dye sensitized solar cells (DSSCs) are considered one of the importantrenewable energy devices owing to their low cost of fabrication and tunable photophysicalproperties. Since 1991, DSSCs attracted much attention and various other types of sensitizersapart from the Ru-metal complxes, such as pure organic sensitizers and porphyrin dyes, havebeen studied for DSSC applications. Significantly higher efficiencies were achieved byoptimizing the sensitizers with appropriate length of the conjugation, various electron donor,and acceptor moieties. In addition to the DSSCs, perovskite solar cells have been recentlyemerged as one of most promising photovoltaic technologies and perovskite materials alsoplays vital roles in achieving excellent conversion efficiencies.The current research proposal involves the development of efficient and eco-friendlysensitizers with chemical stability while focusing on green chemistry of solar cells. Specificaims of the proposal are:A. Design and synthesis of organic photosensitizers for DSSC applications:1. To synthesize the dyes with a novel electron withdrawing indenoisoquinoline core-π bridgeand different anchoring groups for efficient electron transport into the photoanode.2. To identify the organic sensitizers with appropriate conjugation to enhance the molarabsorption toward red shift and suppress the charge recombination.3. To optimize the dyes with electron donating groups to unveil the blocked electron chargeand enhance conversion efficiency.B. Development of ruthenium free organic metal-hybrid sensitizers for DSSCs:1. To investigate and synthesize various ruthenium free organic metal-hybrid sensitizers.2. To explore and identify the appropriate metal for hybrid construction to afford excellentphotovoltaic efficiency.3. To analyze and establish device conditions between dyes and the semiconductor films witha different mesoscopic oxides’ layer.C. Discovery and evaluation of non-toxic perovskites and hole transport layer (HTL)materials for perovskite solar cells.1. To explore non-toxic perovskites to replace the lead for perovskite solar cells.2. To generate novel HTL materials for efficient perovskite solar cells.3. To evaluate various HTLs with different uniform arrays in order to increase the stability.
