■ Bypass diodes in solar modules are widely used to prevent operational quality degradation caused by module quality issues such as hot spots, occlusion, and unevenness.

■ During the application of diodes, performance such as forward conduction and reverse cutoff may occur.

■ In order to verify the performance of diodes and ensure the efficient operation of photovoltaic systems, accurate testing of the thermal performance and thermal runaway of bypass diodes is necessary.
