“…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.

“…Thus, we can conclude that taking into account change in the wide of the SCR doesn't affect the conversion efficiency and that it is removal of majority charged carriers (Rc changes) which is responsible of the type-conversion of the base. Of course, the previous studies taking into account only change in diffusion length don't exhibit type conversion [15,16,17].…”

When solar cells are used for space applications, there are exposed to different types of energetic particles such as protons and electrons. Those energetic particles create defects in the base of the solar cell and lead to the degradation of the performances of the solar cell. Three mainly phenomenon observed in silicon solar cells exposed to 1 MeV electron irradiation are decrease in diffusion length, removal of majority charge careers and enlargement of Space Charge Region (SCR). These three phenomenon lead to the type conversion of the base of solar cell and an anomalous behavior of the short-circuit current for a certain value of the fluences. In the present study, theoretical approach is used to investigate the impact of decrease in diffusion length, removal of majority charge careers and enlargement of SCR on the anomalous behavior of the short-circuit current and type conversion of the base. The electric parameters are studied under AM 1.5 for different fluences of 1 MeV electrons. It was found that, defects responsible for the anomalous behavior of the short-circuit current could appear for different values of the fluences and that, the type conversion of the base is caused by the removal of the majority charged carriers and decrease in diffusion length while the anomaly observed in the evolution of the short-circuit current is caused by the widening of the SCR.

“…Por tratarse de un satélite experimental, no poseía sistema de propulsión propia que le permitiera corregir la pérdida de velocidad producida por el rozamiento con la atmósfera. Como consecuencia de ello y tal cual estaba previsto, su misión finalizó al cabo de alrededor de 10 meses de su puesta en órbita (Bolzi et al 2002). Figura 4 -Satélite SAC-A en el momento de la puesta en órbita Entre otras experiencias y como parte de un acuerdo de colaboración entre la CNEA y la CONAE, la carga del SAC-A incluyó el primer ensayo de celdas solares argentinas en el espacio (Godfrin et al, 1999).…”

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.
