Abstract

The present paper is mainly concerned with the performance improvementof concentrated photovoltaic systems based on convex and Fresnel lenses with different geometrical properties (diameters and focal lengths), subjected to artificial light source “Incandescent lamp” as a simulation to sunlight. A number of experiments have been executed to study their effects on all the electrical parameters of si- mono crystalline photovoltaic cell (2.0 cm×1.0 cm), as well the concentrated light intensity. The morphology of elemental composition and the spectral transmittance applying Scanning Electron Microscope and FT-IR Spectrometer of both the convex -andFresnel -lenses were investigated, demonstrating high optical quality of the lenses. For convex lens with 9.0 cm in diameter, the obtained results show significant direct increasing of shortcircuit current, open circuit voltage, maximum output power, fill factor, and efficiencyof PV cell as well the concentrated light intensity, where their values were increased from 0.32 mA, 0.28 Volt, 0.04 mW, 0.46 and 9.55% as well 0.226 klux up to 6.72 mA, 0.45 Volt, 1.85 mW, 0.6 and 25%, as well 3.5 klux, respectively. Considering the Fresnel lens with diameter of 42.43 cm, the given parameters were increased up to 78 mA, 0.454 Volt, 21.6 mW, 0.6 and 30% as well 35.0 klux, respectively.
