“…The four modules of TEG in series were found to generate an average of 0.003 V at a load of 138ᘯ, giving 65.22 uW of power. Johar et al (2017) performed a temperature analysis in the preliminary studies of shingle-based TEG systems as a renewable energy source. The results showed that the shingle produced an input power of 10.8675 W at 1.5 o C, while the TEG produced 0.21 W at 1.75 o C.…”

The development of renewable energy, especially solar, is essential for meeting future energy demands. The use of a wide range of the solar spectrum through the solar cells will increase electricity generation and thereby improve energy supply. However, solar photovoltaics (PV) can only convert a portion of the spectrum into electricity. Excess solar radiation is wasted by heat, which decreases solar PV cells’ efficiency and decreases their life span. Interestingly, thermoelectric generators (TEGs) are bidirectional devices that act as heat engines, converting the excess heat into electrical energy through thermoelectric effects through when integrated with a PV. These generators also enhance device efficiency and reduce the amount of heat that solar cells dissipate. Several experiments have been carried out to improve the hybrid PV-TEG system efficiency, and some are still underway. In the present study, the photovoltaic and thermoelectric theories are reviewed. Furthermore, different hybrid system integration methods and experimental and numerical investigations in improving the efficiency of PV-TEG hybrid systems are also discussed. This paper also assesses the effect of critical parameters of PV-TEG performance and highlights possible future research topics to enhancing the literature on photovoltaic-thermoelectric generator systems.

“…This paper is reporting on a case study result that is evaluating the feasibility of using a TEG in electricity generation from concrete shingles on a residential roof application. Previous research has shown the potential to harness the thermal energy from the roof up to 75°C on the shingle surface temperature, has been recorded during a hot day [13]. The next step is to establish the amount of electric power output that can be generated from the study of TEG on concrete shingle consisting of a test rig to house a data acquisition device with measuring equipment to sample data from the shingle environment and the TEG environment.…”

A thermoelectric generator (TEG) using Seebeck effect to generate electrical energy in a residential application encompasses a case study of a test rig consisting of a concrete shingle as case study material. This paper explores its behavior and response to changes in temperature throughout the day. Four TEGs in series are mounted on the underside of a shingle. The measurement of the voltage and current response were made to determine the power generated. Using National Instruments as a data acquisition device with thermocouple probes to gather all the necessary data of which are discussed in the paper. From the experiments, the modules were able to generate up to 65.22 µW at 138Ω. This shows a considerable potential of TEG application in residential areas, as they are scalable.

The development of sustainable energy, in particular solar energy, is essential to achieving future energy demands. Solar radiation and heat energy will provide the required electricity needed in daily life. Photovoltaics and thermoelectric energy conversion have been developed over the years. Photovoltaics also converts the ultraviolet-visible areas of the solar spectrum, while thermoelectric uses the Infrared region. Combination of photovoltaic and thermoelectric effects will expand the efficient spectrum range. Research has recently been conducted on hybrid photovoltaic-thermoelectric systems to increase conversion efficiency. The purpose of this work is to review the primary concepts of the hybrid photovoltaics-thermoelectric generator. The work summarises the different methods used to combine hybrid photovoltaic-thermoelectric systems. A proposed PV-TEG Hybrid system using shingle in between the PV and the TEG is presented. Further research on the hybrid system is also encouraged due to encouraging performance
