METHOD FOR STUDYING SPATIAL DISTRIBUTION OF CHARACTERISTICS OF SUSCEPTIBILITY OF PHOTOELECTRIC CONVERTERS IN COMPOSITION OF SOLAR BATTERIES TO OPTICAL RADIATION

摘要

1. A method for studying the spatial distribution of the characteristics of the susceptibility of photoelectric converters in the composition of solar cells to optical radiation, characterized by the use of a visible or IR laser, galvanoscanners, an electronic load unit and a computer equipped with DAC and ADC modules, characterized in that the study is carried out by scanning the surface of the investigated object with a laser beam using galvanic scanners with simultaneous recording of the response of the object under study to radiation. 2. The method according to claim 1, characterized in that an additional low-power laser of the visible range is used, the radiation of which is coaxially aligned with the laser radiation of the above-described device, and the scanning parameters are adjusted in real time according to the visible radiation of the low-power laser. The method according to claim 1 or 2, characterized in that an electronic load unit is used, through which, by changing the load parameters of the test object, automated studies of the dependence of the electrical parameters of the test object, for example, internal resistance, on the parameters of exposure to optical radiation are carried out.
