Spectral Characterization of Solar Cells

Abstract

In this work, experimental measurements of Spectral Response (SR), External Quantum Efficiency (EQE), and Internal Quantum Efficiency (IQE) of different mono-crystalline and multi-crystalline silicon solar cells have been carried out. Additionally, the spectral characterization of a mono-crystal silicon reference cell in the range (UV-VIS-NIR) and a photodiode of GaAsP in the UV-VIS range were verified. The Intensity - Voltage (IV) curves of the solar cells studied were also experimentally determined. Measurements were carried out at the photovoltaic laboratory of the Technological and Renewable Energies Institute (ITER), known as SiCell Lab, and at the Optics Laboratory of University of La Laguna (ULL). From the results obtained we can confirm the future study of new materials, as well as contributing in the development of a laboratory at University of La Laguna which will allow experimental practices in Solar Energy for students of the Master in Renewable Energies.
