Abstract

The invention discloses a solar cell reverse characteristic testing device characterized by at least comprising a support plate used for fixing a solar cell and made of insulation material; the support plate is provided with a first electrode zone connected with the solar cell anode and a second electrode zone connected with the cathode of the solar cell; two first electrode binding posts are arranged in the first electrode zone; two second electrode binding posts are arranged in the second electrode zone; a spring is used for fixing the solar cell on the support plate, and comprises a first compact sheet compacted on the first electrode zone and a second compact sheet compacted on the second electrode zone; ends of the first and second compact sheets are connected in one piece, and the angle between the first and second compact sheets is 110-125 degrees; the first compact sheet is provided with a bolt hole; a digital source meter can communicate data with a computer through a GPIB, and is respectively electrically connected with the first and second electrode binding posts.

Description

technical field [0001] The invention belongs to the technical field of solar battery performance testing for aerospace, and in particular relates to a solar battery reverse characteristic testing device. Background technique [0002] Aerospace solar cells have high reliability requirements and require reverse characteristic testing, which takes a long time and a large number of tests. Existing solar cell test fixtures are mainly designed for electrical performance testing under light conditions, and generally only one cell is tested at a time. The reverse characteristic test takes a long time for a single test, up to several hours. If there are 10 batteries in a batch, and only one piece is tested each time, the total test time will reach hundreds of hours. It is easy to scratch the battery when handling it. The reverse characteristic test signal is generally a DC signal and a pulse sequence. The signal generator can generate arbitrary waveforms. The disadvantage is that...
