The basics of semiconductor and solar cell will be discussed in this section. A semiconductor material has an electrical conductivity value falling between a conductor (metallic copper) and an insulator (glass) s conducting properties may be changed by introducing impurities (doping) namely with Group V elements like …
We observed that a PV cell with a planar silicon surface and no ARC on the front side was able to absorb approximately 60% of the incident light in the 600–1000 …
The cell''s silicon material responds to a limited range of wavelength, ignoring those that are longer and shorter. As the wavelength varies from short to long, the cell''s output rises and falls in a jagged curve. Newer photovoltaic cells designs achieve higher efficiency by converting more wavelengths into useful energy.
Figure 1. Energy band diagram showing the relationship between the bandgap energy and the incident photon energy for photovoltaic cells. From the application side, the need for wireless power transmission [8, 9] has been increasing, for instance, for power beaming to flying drones, spacecrafts [9, 10] etc.For such a distant power …

Temperature has an impact on all solar cell module parameters, such as short-circuit current (I sc), open-circuit voltage (V oc), efficiency, and many others [13, 14].Different from irradiance, I sc and V oc increase when irradiance increases, where temperature has the opposite concept because it is a function of irradiance. When the …
Since the first discovery of solar cells, energy photovoltaic power generation has been considered one of the most active and readily available renewable sources to achieve the green-sustainable global demand [1,2,3].Over the last two decades, solar energy demand increased at an average rate of around 30% per annum [].Effective …
