Caracterización de propiedades ópticas y evaluación de eficiencia de celdas solares sensibilizados con colorantes (DSSCs)

Abstract

The design and implementation of an experimental setup for analyzing the performance of photovoltaic devices and obtaining characteristic curves was carried out.The study on the design and construction of a device for solar simulation from a hybrid light source has been presented. This design, a preliminary downscaled proposal for a solar simulator, combines an array of LEDs of 14 different wavelengths with a halogen bulb. Spectral matching, spatial non-uniformity and temporal instability results are discussed, achieving AAA ratings over a wavelength range of 400-900 nm. In the test plane, a constant and stable radiant flux density of 50 W/m² was achieved in reference to the AM1.5G spectrum. The prototype demonstrated a spectral coincidence of 85%, a spatial non-uniformity of 2.6%, and temporal instability of less than 2%. The main objective of this work is to carry out a solar simulation study based on a smaller scale hybrid lighting system, in perspective with the scaling and implementation processes for the analysis of photovoltaic devices, as well as to carry out characterization and classification tests of solar simulation, making use of hyperspectral spectroscopy elements.
