Books by Keyword: Thermoelectric Generators

Description: This publication is a compilation of brilliant research papers on different areas of clean energy presented at the 2nd meeting of the Africa International Conference on Clean Energy and Energy Storage (AICCEES 2024) held in September 2024 in Nigeria. AICCEES is a conference that seeks to facilitate the clean energy transition for Africa through research and knowledge sharing. Contributions to the conference covered different topics related to clean energy, such as hydrogen development in Africa, mini-grids and hydropower development, sustainable battery manufacturing in Africa, waste to energy, energy access and energy supply in Africa as well as renewable energy systems.

Description: It is well-known that fossil fuels are being rapidly depleted, and that atomic power is rejected by many people. As a consequence, there is a strong trend towards alternative sources such as wind, photovoltaics, solar heat and biomass. Strangely enough, quite another power source is generally neglected: namely, the thermoelectric generator (a device which converts heat, i.e. thermal energy, directly into electrical energy). The reason for this neglect is probably the low conversion efficiency, which is of the order of a few percent at most. However, there are two arguments in favor of the thermoelectric generator. Firstly, we might in effect be at the same point as we were in the early stages of photovoltaics use (it was only in 1954 that the first attractive solar cells, with efficiencies of around 4% were produced). Today, even large modules attain 20%. Secondly, the potential applications of thermoelectric generators are very tempting. Wherever heat is generated, it is amenable to electrical conversion. Energy harvesting via a thermoelectric generator may be accompanied by a further benefit: The use of a solar module inevitably leads to a drastic temperature rise. A thermoelectric generator reduces the temperature rise and therefore offers a double benefit.
