Visible light waves measure between 400 and 700 nanometers, although the sun's spectrum also includes shorter ultraviolet waves and longer waves of infrared. A photovoltaic cell responds selectively to light wavelengths. Those much longer than 700 nanometers lack the energy to affect the cell and simply pass through it.
The graph shows that the output voltage increases with increasing solar irradiance. The result shows that at a maximum solar intensity of 773 Wm –2, the output voltage obtained is 1138 mA. Figure 18.2. The I–V curve of a photovoltaic cell at different solar intensities .
It is known that an ideal SR could not be achieved at long wavelengths because semiconductors in solar cells are unable to absorb photon energies below the bandgap. Hence, while using numerous methods such as solar concentrators and multijunction solar cells to obtain a better SR, degradation appears to be faster than normal.
For most solar cell measurement, the spectrum is standardised to the AM1.5 spectrum; the collection probability of the solar cell, which depends chiefly on the surface passivation and the minority carrier lifetime in the base.
Isc from a solar cell is directly dependant on the light intensity as discussed in Effect of Light Intensity; the spectrum of the incident light. For most solar cell measurement, the spectrum is standardised to the AM1.5 spectrum;
In wavelength-selective CPV technologies, also referred to in the literature as “spectral splitting,” incoming direct sunlight is spectrally divided and concentrated onto typically high-efficiency solar cells (such as III-V multi-junction solar cells).
