“…Different contracts subscribed between CNEA and the Argentine National Commission for Space Activities (CONAE) promoted the development of photovoltaic arrays for space applications. Activities in this field have included: development of computational codes for solar array design and performance prediction, test of solar devices in Argentine satellites, on-ground radiation damage experiments, and development of characterization and device simulation techniques, as reported elsewhere [1][2][3][4][5][6][7][8].…”

This work presents particular aspects dealing with the measurement of the spectral response (SR) on multijunction solar cells, a tricky and somewhat complex issue. Here, we demonstrate the development of a facility to measure SR between 300 nm and 1900 nm on III–V solar cells for space applications, particularly oriented to measure large area triple junction (3J) InGaP/GaAs/Ge cells, although it can be utilized to measure other types of devices. The equipment is based on narrowband interference filters and a novel and low cost approach of two dichroic lamps as bias light source, used to select the subcell to be measured using suitable bandpass filters, whereas a simple incandescent halogen lamp is used to generate the monochromatic light beam. The signal is measured on an appropriate resistance inserted in a serial circuit using a lock-in amplifier. Measurement is fully automated, which allows operator independent results. Detailed studies performed on bias spectrum conditions and voltage biasing for these types of cell are showed, as well as a thorough treatment of the uncertainty and measurement error sources. Preliminary SR measurement results demonstrate the good performance of this setup. As an example, the results of the application of this setup to analyze radiation damage induced by 10 MeV protons are shown.

“…El objetivo científico de la misión Aquarius/SAC-D está orientado a obtener nueva información climática a partir de las mediciones de salinidad y una nueva visión de la circulación y procesos de mezcla en el océano, así como detectar focos de alta temperatura en la superficie terrestre para la obtención de mapas de riesgo de incendios y humedad del suelo para alerta temprana de inundaciones. El desarrollo de los sensores solares gruesos forma parte del Subproyecto Paneles Solares como parte del proyecto Aquarius/SAC-D que se encuentra enmarcado dentro del convenio CNEA-CONAE para el desarrollo, integración y ensayo de paneles solares para misiones satelitales (Alurralde et al 2010).…”

En el año 1998 se inició en la Comisión Nacional de Energía Atómica (CNEA) el desarrollo de radiómetros fotovoltaicos de bajo costo, utilizando como elemento sensor celdas fotovoltaicas de silicio cristalino fabricadas en el Laboratorio Fotovoltaico del Departamento Energía Solar del Centro Atómico Constituyentes. Se diseñaron, fabricaron y calibraron distintos prototipos para analizar el comportamiento de estos sensores y evaluar sus limitaciones. Actualmente se han distribuido en distintos laboratorios del país prototipos comerciales para su evaluación final en campo. Los sensores fabricados tienen tanto aplicaciones terrestres como espaciales en satélites artificiales. En particular, el primer experimento de celdas solares argentinas en el espacio, a bordo del satélite SAC-A, incluyó la fabricación de los sensores de posición del satélite que formaban parte del sistema de orientación del satélite respecto al Sol. En este trabajo se presenta el desarrollo y estado actual de los sensores fotovoltaicos de silicio monocristalino fabricados en la CNEA, así como sus aplicaciones espaciales y terrestres.

“…In this model, the capacitance of each individual subcell was included, and their values were estimated by C–V measurements of isotype cells. Finally, taking into account the two analyses presented, a solar array module of the SAC‐D/Aquarius satellite [] was simulated in order to estimate the errors made during measurements performed out of standard.…”

This paper presents a method to predict the I-V characteristic of triple junction InGaP/GaAs/Ge solar cells when different illumination spectra are used, and it is based on the measurement of a set of commercial isotype cells together with numerical simulations. The study includes the utilization of continuous and pulsed light sources. Several spectra were considered for the continuous light sources, where different subcells limit the current of the tandem cell. For pulsed light sources, a dynamical analysis was carried out by simulating a triple junction cell through PSpice software. For the simulations, the subcell capacitances were estimated and introduced into an electrical model of the triple junction. When a fast pulse in the multiflash I-V measurement technique is used, dynamical effects associated with this kind of source were observed and accounted for by the simulations. It was established that the dynamical effects did not affect the I-V characteristics measured with this technique. Finally, the proposed method and analysis were successfully applied to the electrical characterization of the Aquarius/SAC-D Argentine satellite solar array modules.
