The Department for Solar Energy (DSE) at the CNEA in Buenos Aires, Argentina, performs both technological and basic research activities on photovoltaic energy for space and terrestrial applications. The Solar Energy Department has 35 long years of history. One of the most relevant lines of work is tied to the context of the Argentinean National Space Project carried out by the National Space Agency (CONAE) focusing on the development of the solar arrays for Argentinean artificial satellites. The first experiment of argentine solar cells in space started with the SAC-A satellite, launched in 1998. The last success story was in June 2011 when the Argentinean Satellite Aquarius/SAC-D was launched from the USA (NASA), all solar panels that powered the satellite instruments were entirely designed and assembled in the group and are currently working normally as expected.
The DSE under the direction of Dr. Julio Duran is also involved in the technological application of solar energy for terrestrial with a recently funded project that will constitute the first experience of urban distributed solar energy generation in Argentina. Basic research lines in terrestrial photovoltaics include investigation of III-V semiconductors for multi-junction solar cells. A most recent line of work is currently investigating organic-inorganic solid state hybrid solar cells. The approximation includes selectively tailoring the inorganic matrix to control the heterojunction via sol-gel synthesis of a highly crystalline titania structure in combination with an organic material incorporated via solution impregnation in a BHJ-fashion.
