This paper presents the evolution in the strategy to assess the reliability of III-V solar cells and a new thermal ageing test carried out over GaAs single junction solar cells at three different temperatures (130, 150 and 170ºC). The perimeter of the solar cells has been protected with silicone, which seems to be an effective way of enhancing the reliability of the solar cells. A preliminary analysis of the results indicates a mean time to failure (MTTF) one order of magnitude larger than the one obtained in a previous thermal test with the perimeter uncoated.

“…The actual performance of a concentrator system with high chromatic aberration is expected to be within these two extremes cases as already proven by experimental results (12). Predicting this behavior is not intuitive at all, therefore simulations based on distributed model are very useful to understand this phenomenon (2,11,(13)(14)(15)(16)(17)(18).…”

Abstract. This paper presents the mechanisms of efficiency losses that have to do with the non-uniformity of the irradiance over the multi-junction solar cells and different measurement techniques used to investigate them. To show the capabilities of the presented techniques, three different concentrators (that consist of an acrylic Fresnel lens, different SOEs and a lattice matched multi-junction cell) are evaluated. By employing these techniques is possible to answer some critical questions when designing concentrators as for example which degree of non-uniformity the cell can withstand, how critical the influence of series resistance is, or what kind of non-uniformity (spatial or spectral) causes more losses.

“…Therefore, a 3-D model is required to precisely model luminescent coupling effects in concentrator solar cells where the incident spectrum and temperature in each junction vary in space. Previous research has demonstrated a 3-D distributed circuit model that can perform modeling of non-uniform effects in solar cells [4][5] [6], however, to the best of our knowledge, no published work has shown the extension of 3-D modeling to luminescent coupling effects.…”
