What is the difference between polysilicon and monocrystalline silicon photovoltaic cells?
In the photovoltaic technology and micro-semiconductor inverter technology today, the rapid development of the use of silicon single crystal produced by solar cells can be directly into solar energy into light, to achieve the beginning of the green energy revolution.
Can be used for diode-level, rectifier device-level, circuit-level and solar cell-level single crystal products production and deep processing and manufacturing, and its follow-up products integrated circuits and semiconductor separation devices have been widely used in various fields, military electronic equipment also occupies an important position The
Monocrystalline silicon is made of polycrystalline silicon by a single crystal furnace, but also useful for the preparation of monocrystalline silicon melting. Polysilicon is the direct raw material for the production of monocrystalline silicon, which is the basic material of electronic information for semiconductor devices such as contemporary artificial intelligence, automatic control, information processing, photoelectric conversion and so on. Known as the "cornerstone of the microelectronics building."
Monocrystalline silicon cells with high battery conversion efficiency, good stability, but the higher cost. Polycrystalline silicon cells are less costly and slightly lower in conversion efficiency than straight-drawn monocrystalline silicon solar cells, with various defects in materials such as grain boundaries, dislocations, microdefections, and impurity carbon and oxygen in materials, as well as tarnished during process Transition metal.
