About this Research Topic
There are two major branches related to solar collector technologies: flat plate collectors and concentrating solar collectors. Flat plate collectors mainly consist of a photovoltaic module and a solar hot water panel. The solar hot water panel can collect heat by absorbing sunlight, through capturing solar radiation in the form of electromagnetic radiation from infrared (long) to ultraviolet (short) wavelengths. However, photovoltaic modules only absorb specific ranges of spectral irradiances that match the bandgap. To improve performance and to save cost, concentrating solar collectors is the solution to concentrate direct normal solar irradiance onto the receiver. This strategy can increase the intensity of solar irradiance and hence the temperature of the receiver, therefore increasing power conversion efficiency for the solar thermal receiver whilst also reducing the usage of semiconductor materials for the concentrator photovoltaic receiver. There are many innovative ways to design solar concentrators and receivers to increase performance and to reduce cost. These are the critical means which render solar energy to be competitive with other types of renewable energies as well as fossil fuels. To allow global scientists and engineers to share their thoughts and ideas, this Research Topic will create a platform for topics related to the technologies of concentrating solar collectors for various applications including:
• concentrator photovoltaic systems,
• solar thermal systems,
• solar furnace systems,
• high temperature material processes,
• heliostat fields,
• solar power tower systems,
• dish-Stirling systems,
• active daylighting systems,
• water desalination systems,
• solar drying systems,
• hydrogen production
Furthermore, research studies that can provide support to concentrating solar power technologies are welcome to submit to this Research Topic. For instance, contributions-related themes include thermal heat storage systems, fuel cells, fiber optics for sunlight transmission, solar powered lasers, ray-tracing algorithms, sun-tracking systems, thermodynamic cycles, heat pipes, vapor chambers, cooling systems for concentrator photovoltaic systems, energy policy, and optics theory. Furthermore, this Research Topic also welcomes studies relating to the social sciences, economic impact and government policies such as environmental issues related to concentrating solar power, land usage for large solar power plant, long-term impact of concentrating solar power systems and economic evaluation. We wish to provide a platform for researchers to communicate and share their latest findings in concentrating solar power technologies.
