Evaluation of the Performance of Photovoltaic System under different Wavelengths from Artificial Light in a Controlled Environment

Abstract

Photovoltaics cell behave in a unique way when light falls on it. The objective of this work is to evaluate the performance of photovoltaic system under different wavelengths from artificial light in a controlled environment. Measurements were first taken from the PV module in the absence of the filters, followed by each filter been placed individually and measurement taken correspondingly. From the results obtained the PV module was most efficient when the yellow colored filter was employed and least efficient with the blue filter (revealing a difference of 2% in efficiency between them). Nevertheless, the photovoltaic module surpassed the efficiencies reached with the application of the colored filters when left open to the natural spectrum.
