摘要：
Solar energy has been considered for many years one of the most reliable and predictable renewable energy resources for the production of both electricity and heat. At the moment, renewable energy market is mainly focused on photovoltaics and solar thermal systems. Quite recently, the implementation of thermoelectric generators in solar energy conversion systems, as an alternative method for exploiting the potential of this huge resource, has attracted increasing attention. In this paper, the performance of a thermoelectric-based solar conversion unit is investigated computationally, using ANSYS Workbench v. 14.0 CAE Software. The electrical output of the system under consideration has been evaluated and performance prediction has been conducted under various operating conditions, demonstrating maximum power output of 33.7 W. Moreover, different techniques are discussed in order to enhance power output and optimize systetn operation according to the incoming solar irradiation levels, which can differ significantly throughout the year.
