Customer ServiceIn the present article, a state-of-the-art of solar cells operating under thermal stress, at temperatures >100°C, is established. In the following section, physics governing the sensitivity to temperature of solar cells is summarized, with an emphasis on the critical elements for pushing the limits to high-temperature levels.
In regions characterized by extreme temperatures, such as hot deserts or cold climates, solar cells may undergo variations in efficiency (Osma-Pinto & Ordóñez-Plata, 2019). The dynamic response of solar cells to temperature extremes is a critical consideration for system designers.
The fundamental physics governing the thermal sensitivity of solar cells and the main criteria determining the ability of semiconductor materials to survive high temperatures are recalled. Materials and architectures of a selection of the solar cells tested so far are examined.
Thermal effects in the context of solar cells refer to the changes in their electrical and optical properties due to variations in temperature. As solar cells operate, they invariably generate heat.
The problem with solar cell efficiency lies in the physical conversion of sunlight. In 1961, William Shockley and Hans Queisser defined the fundamental principle of the solar photovoltaic industry.
When multiplying the absorption angle Ω a, which means the solar cell will collect much more solar energy in unit area and much more heat will be generated, there will be a significant temperature rise in the cell if the cooling system is not well enhanced.
