Mathematical and experimental analysis on Solar Thermal energy harvesting performance of the textile-based Solar Thermal energy collector
Renewable Energy, 2018Co-Authors: Xiaomei Cheng, Zhaoling LiAbstract:Abstract Textile-based Solar Thermal energy collectors (TSTECs) are one kind of novel flexible Solar Thermal harvesting products, which can be widely applied in the fields of building roofs and facades. In this paper, a proposed numerical model was developed to calculate the Solar energy harvesting performance of textile-based Solar Thermal energy collectors with different layers of textile composites. Also, the outdoor tests were performed to confirm the effectiveness of the designed system and to validate the simulation results. It is found out that the numerical results showed a good agreement with the experimental results. As a consequence, the developed numerical model serves as a useful tool to predict and design the most promising and optimal performance of TSTEC with high efficiency. This research brings some progress in the field of textile-based Solar Thermal energy harvesting products and they can potentially extend to be widely used in an industrial application that needs heating supply in low-to-medium temperature level.

Solar‐Thermal Energy Conversion and Storage Using Photoresponsive Azobenzene‐Containing Polymers
Macromolecular rapid communications, 2019Co-Authors: Hans-juergen ButtAbstract:Photoswitchable compounds are promising materials for Solar-Thermal energy conversion and storage. In particular, photoresponsive azobenzene-containing compounds are proposed as materials for Solar-Thermal fuels. In this feature article, Solar-Thermal fuels based on azobenzene-containing polymers (azopolymers) are reviewed. The mechanism of azopolymer-based Solar-Thermal fuels is introduced, and computer simulations and experimental results on azopolymer-based Solar-Thermal fuels are highlighted. Different types of azopolymers such as linear azopolymers, 2D azopolymers, and conjugated azopolymers are addressed. The advantages and limitations of these azopolymers for Solar-Thermal energy conversion and storage, along with the remaining challenges of azopolymer-based Solar-Thermal fuels, are discussed.

hierarchical graphene foam for efficient omnidirectional Solar Thermal energy conversion
Advanced Materials, 2017Co-Authors: Miao Tang, Baolu Guan, Mingzhan Wang, Jingyuan Shan, Zhaolong Chen, Kexin Wang, Jiawei Yang, Feifan Wang, Hailin PengAbstract:Efficient Solar–Thermal energy conversion is essential for the harvesting and transformation of abundant Solar energy, leading to the exploration and design of efficient Solar–Thermal materials. Carbon-based materials, especially graphene, have the advantages of broadband absorption and excellent photoThermal properties, and hold promise for Solar–Thermal energy conversion. However, to date, graphene-based Solar–Thermal materials with superior omnidirectional light harvesting performances remain elusive. Herein, hierarchical graphene foam (h-G foam) with continuous porosity grown via plasma-enhanced chemical vapor deposition is reported, showing dramatic enhancement of broadband and omnidirectional absorption of sunlight, which thereby can enable a considerable elevation of temperature. Used as a heating material, the external Solar–Thermal energy conversion efficiency of the h-G foam impressively reaches up to ≈93.4%, and the Solar–vapor conversion efficiency exceeds 90% for seawater desalination with high endurance.

PV–Enhanced Solar Thermal Power
Energy Procedia, 2014Co-Authors: Werner PlatzerAbstract:Abstract Solar electricity generation using concentrating Solar Thermal collectors faces the challenge of strongly decreased levelized electricity costs by photovoltaic power plants. One of the selling points favouring Solar Thermal power is the possibility to generate dispatchable power. Concepts discussed here are Solar hybridization of conventional or biomass Thermal power plants. Another option is the use of Thermal energy storage (TES) charged with Solar heat which allow to drive the generation of electricity by steam turbines also during hours with no or low Solar irradiation. Usually the Solar fields of Solar Thermal power plants utilizing storage with several hours capacity will be much larger than those of plants without storage. This contributes to much higher cost per installed capacity in the case of storage utilization. In this paper the question shall be tackled in a rather fundamental way whether the combination of Solar Thermal power with cheaper photovoltaic systems plus minimum Solar Thermal power with storage may give lower levelized electricity cost plus dispatchability than either photovoltaics alone or Solar Thermal power alone. For the investigation of a combined PV-enhanced Solar Thermal power plant no specifically developed software was available. Therefore the simulation of the photovoltaic plant and the Solar Thermal power plant including TES was done individually. For the Solar Thermal power plant TES storage capacity and Solar field area were varied. Solar field area ranged between Solar multiple of two and below one. The latter choice would have been senseless without PV-enhancement. Hourly power generations profiles over a complete year were combined and matched in order to generate electricity according to a prescribed demand curve. Using dispatch prescriptions the scheduling of Solar Thermal power was controlled. With typical generic cost data and variations of those in a sensitivity study the combined levelized electricity cost were determined and analysed. Photovoltaic generation and Solar Thermal power generation via Thermal energy storage may produce high annual capacity factors above 50% due to dispatchable Solar power from the Thermal storage. Depending on the climatic conditions and on seasonal and daily load profiles the combinations of photovoltaic and Solar Thermal power may change. Many open questions have to be solved in order to proceed with the basic idea of PV-enhanced Solar Thermal power generation. Real cost data and optimization requires a specific project case. Then also the selection of the most promising photovoltaic technology and the different Solar Thermal technologies may be discussed in more detail.
