Research on Near Space Solar Cells Acquisition and Test System

In this paper, a set of near space solar cell accurate test system is designed. The system includes high-altitude scientific balloon, solar tracking mechanism and solar cell high-precision acquisition equipment. This paper solved the problem of high accuracy acquisition of solar tracking control system for high-altitude balloon solar cell test in extreme environment, Continuous tracking and anti-shake and other key technical issues. The paper achieved near space I-V curve measurement for the first time, and the initial analysis of the system test results are reasonable, reliable and stable. The paper work provides a new idea and solution for our country near space solar cells accurate measurement.
