Features of testing the characteristics of micro-sized photovoltaic converters of laser radiation

A measuring stand using optical fiber for transmit- ting laser radiation has been developed for testing micro-sized (30–300 $\mu$m) photovoltaic converters. The setup allows to study the main characteristics of small-sized photovoltaic converters: volt-ampere characteristics, response speed, and the spectrum of electroluminescence. Features of measuring photovoltaic parameters of converters of various types are shown.
