In conventional photovoltaic systems, the cell responds to only a portion of the energy in the full solar spectrum, and the rest of the solar radiation is converted to heat, which increases the temperature of the cell and thus reduces the photovoltaic conversion efficiency [[8], [9], [10]].Silicon-based solar cells are the most productive and widely traded cells available [11, 12].

Solar power is very cheap compared to other sources of energy generation. They are also abundant and suitable for several applications. The maintenance cost for solar power systems is also low. The main demerit is the fact that they are subject to weather intermittency; hence will require an energy storage system that will add to the overall cost of …
This is because the PV efficiency decreases as C increases (Fig. 3); simultaneously, the solar energy obtained by the PV cells increases, and the combined effect of the two results in the generation of the maximum output power. Moreover, the better the cooling effect, the greater is the maximum output power that can be obtained by the system. As shown in
Unlike solar PV, CSP is very cost-sensitive to scale and favors large-scale power generation (generally ≥50 MW) to minimize energy production costs which requires relatively large capital investments and financial risks (partly due to the relatively greater technical complexity of the technology) that not everyone can take up. In the early commercialization of …
