Technical Field

[0002] Solar photovoltaic cells (PV cells for short) are used to directly convert sunlight into electrical energy. Currently, most ground-based photovoltaic systems use silicon solar cells based on silicon, which can be divided into monocrystalline silicon, polycrystalline silicon, and amorphous silicon solar cells. In terms of comprehensive performance such as energy conversion efficiency and lifespan, monocrystalline silicon and polycrystalline silicon cells are superior to amorphous silicon cells. Polycrystalline silicon has a lower conversion efficiency than monocrystalline silicon, but it is cheaper.

[0003] The present disclosure, CN212258901U, discloses a hidden crack infrared detector for photovoltaic power station modules, comprising a detection box and a base.
