Description

Technical Field

[0001] This invention relates to the field of perovskite multilayer module technology, specifically to a perovskite multilayer module testing system. Background Technology

[0002] Perovskite tandem modules are a new type of photovoltaic module, combining perovskite and traditional crystalline silicon modules. A perovskite thin film is deposited on the surface of the crystalline silicon module. The perovskite thin film first absorbs a portion of sunlight to generate electricity, while the remaining sunlight passes through the film and is absorbed and converted into electricity by the crystalline silicon module. Because the two modules absorb different spectral bands, they can each exert their photoelectric conversion performance, reducing light energy waste. However, due to the significant difference in voltage and current generated by the two modules, they cannot be connected in series or parallel in the circuit. This characteristic makes perovskite tandem modules physically equivalent to two independent modules with very different characteristics, requiring each to output independently.

[0003] When conducting precise outdoor power or power generation tests, traditional test systems designed for single-type components are no longer sufficient. The test system must possess the capability to perform synchronous, parallel, rapid IV curve scanning or MPPT real-time tracking measurements on two outputs with different characteristics. This is the core technological bottleneck and challenge faced by existing general-purpose test systems.
