Book Synopsis Photovoltaic Devices Using Photosynthetic Protein Complexes by : Rupa Das
Download or read book Photovoltaic Devices Using Photosynthetic Protein Complexes written by Rupa Das and published by . This book was released on 2004 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photosynthetic proteins have been used as an active material in design of organic solar cells. Traditional organic solar cells have the limitation of not being able to absorb light in the visible-NIR region of the solar spectrum. This region corresponds to over 70% power of the total solar radiation. Using molecular proteins obtained from nature these limitations can be overcome. Biological photosynthetic complexes contain reaction centers with a quantum yield of>95% and a bandgap of less than l.leV allowing absorption in the 600-11 00nm visible-NIR range. Two types of photosynthetic complexes are employed to demonstrate the generality of the solid state integration technique to make solar cells. The simplest photosynthetic complex used is a bacterial reaction center (RC), isolated from the purple bacterium R. sphaeroides. The other protein being used is Photosystem I (PSI), a much larger complex, which is isolated from spinach chloroplasts. Electronic integration of devices is achieved by depositing organic semiconducting protective layer over a self-assembled monolayer of photosynthetic reaction centers oriented via an engineered metal-affinity polyhistidine tag. Various analytical and spectroscopic techniques have been used to examine solution spectrum and solid state device characteristics. Reasonable efficiencies have been obtained which demonstrates applicability of such techniques. The efficiency obtained is higher than a wet cell made using same proteins. The next immediate goal is to optimize processing conditions and therefore improve efficiency to reach levels comparable traditional organic solar cells.
Book Synopsis Integration of Photosynthetic Pigment-protein Complexes in Dye Sensitized Solar Cells Towards Plasmonic-enhanced Biophotovoltaics by : Yiqun Yang
Download or read book Integration of Photosynthetic Pigment-protein Complexes in Dye Sensitized Solar Cells Towards Plasmonic-enhanced Biophotovoltaics written by Yiqun Yang and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Solar energy as a sustainable resource is a promising alternative to fossil fuels to solve the tremendous global energy crisis. Development of three generation of solar cells has promoted the best sunlight to electricity conversion efficiency above 40%. However, the most efficient solar cells rely on expensive nonsustainable raw materials in device fabrication. There is a trend to develop cost-effective biophotovoltaics that combines natural photosynthetic systems into artificial energy conversion devices such as dye sensitized solar cells (DSSCs). In this research, a model system employs natural extract light-harvesting complex II (LHCII) as a light-absorbing sensitizer to interface with semiconductive TiO2 and plasmonic nanoparticles in DSSCs. The goal of this research is to understand the fundamental photon capture, energy transfer and charge separation processes of photosynthetic pigment-protein complexes along with improving biophotovoltaic performance based on this model system through tailoring engineering of TiO2 nanostructures, attaching of the complexes, and incorporating plasmonic enhancement. The first study reports a novel approach to linking the spectroscopic properties of nanostructured LHCII with the photovoltaic performance of LHCII-sensitized solar cells (LSSCs). The aggregation allowed reorganization between individual trimers which dramatically increased the photocurrent, correlating well with the formation of charge-transfer (CT) states observed by absorption and fluorescence spectroscopy. The assembled solar cells demonstrated remarkable stability in both aqueous buffer and acetonitrile electrolytes over 30 days after LHCII being electrostatically immobilized on amine-functionalized TiO2 surface. The motivation of the second study is to get insights into the plasmonic effects on the nature of energy/charge transfer processes at the interface of photosynthetic protein complexes and artificial photovoltaic materials. Three types of core-shell (metal@TiO2) plasmonic nanoparticles (PNPs) were conjugated with LHCII trimers to form hybrid systems and incorporated into a DSSC platform built on a unique open three-dimensional (3D) photoanode consisting of TiO2 nanotrees. Enhanced photon harvesting capability, more efficient energy transfer and charge separation at the LHCII/TiO2 interface were confirmed in the LHCII-PNP hybrids, as revealed by spectroscopic and photovoltaic measurements, demonstrating that interfacing photosynthesis systems with specific artificial materials is a promising approach for high-performance biosolar cells. Furthermore, the final study reveals the mechanism of hot electron injection by employing a mesoporous core-shell (Au@TiO2) network as a bridge material on a micro-gap electrode to conduct electricity under illumination and comparing the photoconductance to the photovolatic properties of the same material as photoanodes in DSSCs. Based on the correlation of the enhancements in photoconductance and photovoltaics, the contribution of hot electrons was deconvoluted from the plasmonic near-field effects.
