Special Issue Information

Dear Colleagues,

We are inviting submissions to a Special Issue of Energies on the subject area of Solar Thermoelectric Generators (STEGs).

STEGs are thermoelectric generators that use solar radiation as a heat source. STEGs are very simple, reliable, and lightweight, and they may operate with high-temperature high-efficiency thermoelectric modules. All of these features, among others, have recently increased the interest of using STEGs to provide electrical energy in off-grid applications, to improve the energy efficiency of systems and facilities, and so on.

  • This Special Issue focuses on the analysis, design, and implementation of STEGs.
  • Potential topics include, but are not limited to, the following:
  • STEG design (cold and/or hot heat sinks, structure design of thermoelectric modules, etc.)
  • Performance analysis of STEG systems
  • Optimization studies of STEG systems
  • High-performance thermoelectric materials for STEG applications
  • Non-conventional applications of STEG (windows, façades, roads, etc.)
  • Micro-power STEG systems
  • STEG for space applications
  • STEG integrated in other energy systems
  • Hybrid PV-STEG systems

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Energies is an international peer-reviewed open access semimonthly journal published by MDPI.

The solar updraft tower (SUT) is a renewable power generation system that uses natural air convection from the ground that is heated by solar radiation. Placing flow-guide structures within the collector of the SUT can enhance aerodynamic performance, and hence, increase the kinetic power. Here, we propose a central guide post (CGP) structure in the SUT that controls updraft flow. The effect of the CGP geometry on aerodynamic performance was investigated using computational fluid dynamics modeling (ANSYS Fluent 19.2) to show that a CGP can play a positive role by preventing stagnation of the airflow at the center of the collector, resulting in increased kinetic power output (up to ~2%). However, excessively long CGPs retarded airflow, resulting in a dramatic decrease in kinetic power output. We also investigated a system with both a CGP (to improve aerodynamic performance and minimize energy loss) and a heat-exchange baffle (to maximize thermal energy transfer). When installed with a proper distance between components, the CGP and baffle showed a combined effect of increasing the kinetic power output by up to 10%. We expect that our proposed method using the CGP and baffle system will contribute to the development of better future SUT technology. Full article
