Rational Design and Synthesis of Novel Materials for Solar Cell Applications

Project Details


Scientific and technological developments of any country generally rely on its own efforts and access to the energy supplies. Most developed countries accomplish their energy needs through burning fossil fuels which are rapidly depleting and also their extensive use is causing serious environmental issues. With each country executing lawful approaches to curb the total CO2 level and save future of the planet, pursuing clean and renewable energy sources to fulfill the total energy demands has become an important and quite challenging task. Research communities are trying to advance reliable and alternative green energy sources such as photovoltaic (PV) technologies, which convert solar energy to electrical energy, to meet the rising energy demand. Silicon based PV technology, which holds its ground for clean electricity production, is the first representative for PV as a commercial product. But the main challenge is to obtain economically liable PV power grids and enable large scale production. In this aspect, the renewable energy devices such as dye sensitized solar cells (DSSCs) and perovskite solar cells (PSCs) have paved to be new alternative PV technologies. These devices have attracted special attention for their low cost, tunable properties, and respectful photo-conversion efficiencies. The dye sensitizers and hole transporting materials (HTMs) are the major contributors for the excellent performances of DSSC and PSC, respectively. Therefore, advancement of these materials was carried out in our research based on the followings: 1) Discovery of novel sensitizers and HTMs that can contribute to the stability of efficient PV cells; 2) Broad studies of material configuration and compositions in devices to best match the synthesized sensitizers and HTMs; 3) Fine tuning of the devices architecture to optimize overall cell performance.The current research proposal involves the development of efficient materials with chemical stability while focusing on green chemistry of solar cells. Specific aims of the proposal are: A. Discovery of new photovoltaic materials for DSSCs and PSCs applications:1. Design and synthesis of various ruthenium free organic metal-hybrid sensitizers with experimentally screened metals for hybrid construction that can lift the performance for DSSC.2. New approaches to improve the formation of perovskite layers in PSCs trough incorporating HTMs designed and synthesized with hydrophilic nature. 3. Design and preparation of HTMs for PSC applications based on donor-donor, donor-acceptor or donor-acceptor-donor configurations.B. Evaluation of power conversion efficiencies (PCEs) and other photovoltaic properties of DSSCs and PSCs:1. Screening the prepared, configurationally and structurally different, materials to understand the requirements in molecular modifications through interpreting the photophysical and photochemical data.2. Adjusting the compositions and architect of the devices to better suit to the designed materials with collaborators.3. Analyzing the device interfacial mechanism and plan necessary modifications to generate novel, stable and excellent performing DSSCs and PSCs.
