Popis:	In this paper we present the comparisons of noise spectroscopy, I-V characteristic and microplasma detection of silicon concentrator photovoltaic (CPV) cell with very high efficiency. Efficiency reaches to 38 %. We studied two groups with different technologies (A and B). Each group had 6 samples. The samples were quality screened using noise analysis. From the measurement results it follows that the noise spectral density related to defects is of 1/f or generation-recombination types. G-R noise and burst noise is not fundamental noise and therefore can by use as a quality indicator.
