Performance Analysis of Silicon Technologies Photovoltaic Cells Using Artificial Light Source in Different Spectra

Photovoltaic (PV) devices have a spectral response that depends directly on the light spectrum wavelength, causing their performance to be significantly modified with the spectral distribution of the incident radiation. It is essential to consider that the spectrum of sunlight varies with the location, climate, season, time of day, and even the angle of incident rays. Thus, it is essential to evaluate the behavior of PV technologies in different light spectrums to obtain the best conditions for the installation of PV systems and minimize performance losses. From this perspective, there is great difficulty in analyzing the efficiency of these devices in outdoor tests, considering specific light spectra since the solar spectrum is very broad. In order to contribute to this aspect, this work proposes the use of a device for conducting indoor experimental tests with artificial light based on power RGB light-emitting diode (LED) to analyze the performance of PV cells using amorphous silicon (a-Si), polycrystalline silicon (p-Si), and monocrystalline silicon (m-Si) technology in spectra of specific light. This analysis is performed by obtaining the characteristic curve of the current and voltage of the tested cells and their extracted electrical parameters.
