Electroluminescence (EL) diagnosis has been widely used as a powerful tool to analyze solar cell performance photographically. Portable Near Infrared (NIR) camera with high-sensitive Si senor will be demonstrated to detect weak EL from PV cells and modules. Precise evaluation will be feasible for various kinds of solar cells (crystalline Si, amorphous Si, CIGS thin film cells, etc.) in dark rooms. In addition, with the help of appropriate power source PV modules and strings of installed mega-solar systems can be inspected “on site” and “as is” states, which will be valuable to maintain the...

While the Earth-base laboratories keep trying very hard to elucidate on the nature of the elusive dark matter particles the other very promising avenue to test and/or falsify potential dark matter candidates resides in astrophysical observations. In this context our own Galaxy - the Milky Way - with its unique set of satellites shows potential to serve as a extraterrestrial laboratory for dark matter. The very physical nature of dark matter particles and especially the differences between the main candidate, the neutralino of Cold Dark Matter (CDM), and its currently strongest competitor, the...

Decoherence and "einselection" have important roles in quantum physics, and are understood to be important in the emergence of classical behavior. Traditional discussions of einselection all assume an arrow of time. The extent to which einselection (and thus the emergence of classicality) is tied to an arrow of time has possibly deep implications for cosmology. In this talk I present some early results on this topic based on calculations in a toy model related to the classic Caldeira Leggett model, which I solve unitarily in all regimes. This talk will include introductory material, and...

Prof. Andreas Albrecht (University of California, Davis, USA)

Abstrakt:

I review the current status of cosmic inflation, including successes and open questions. I also scrutinize the question of the famous cosmological “tuning puzzles” and analyze the extent to which inflation does and does not resolve these. I explain why I think the open questions about inflation are deeply scientifically exciting. They should not be regarded as “failures” of inflation, nor should they be swept under the rug.
