Energy needs have increased with global advancements and industrial revolutions. Electrical energy utilization shares a huge amount of energy with residential and industrial loads. Traditional energy resources are expensive and polluting, producing greenhouse gasses, which is a major environmental concern. Solar energy utilization is a cost-effective, sustainable, and green solution to meet the ongoing energy demand. Concentrator photovoltaic (CPV) systems are developed for energy conversion by providing high efficiency using multi-junction solar cells. This paper provides an overview of the recent optical developments in CPV systems and emerging technologies that are likely to shape the future of CPV systems. The objective of this article is to provide an overview of the issues that need to be resolved to improve the geometrical concentration, acceptance angle, uniformity, and optical efficiency of CPV systems. A comprehensive comparison is also presented on different types of solar concentrators. In addition, future research directions are presented to facilitate the continued growth and success of CPV systems. Furthermore, this review article gives an up-to-date and widespread overview of CPV technology, assesses its potential for various applications, and distinguishes the challenges and opportunities for future research and development.

“…Besides that, the electrical energy produced by the TEG also can be used, which further increases the performance of the system. There is research conducted on the PV-TEG cogeneration system (PTCS) [7,8]. However, this research does not specify any maximization of electrical output since the output is either an open circuit or connected to a dummy load.…”

Photovoltaic (PV) converts solar energy to electrical energy directly. During this process, the PV produce energy losses in the form of heat energy. To improve the system's efficiency, this heat energy is converted into electrical energy using the thermoelectric generator (TEG). The PV and TEG have a nonlinear current-voltage characteristic and it requires a power converter with maximum power point tracking (MPPT) to properly extract the energy. There are several configurations of power converters available for the PV-TEG cogeneration system (PTCS). Nonetheless, the literature that compares the performance of the configurations is unavailable. This paper compares 4 configurations for the PTCS, which include the separate boost full MPPT (SBFM), separate boost partial MPPT, series source boost MPPT, and PV boost MPPT with series TEG. The boost converter with perturb and observe MPPT method is used for all configurations to ensure a fair comparison. The results show that SBFM can efficiently extract the energy from both PV and TEG up to 98.5%. The other configurations can efficiently extract energy from the PV (more than 98.5%). However, the energy extracts from the TEG have a low efficiency down to 87%. Overall, the configuration chosen for the PTCS affects the efficiency of the system.
