A **solar cell**, or **photovoltaic** cell, is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon. It is a form of photoelectric cell, defined as a device whose electrical characteristics, such as current, voltage, or resistance, vary when exposed to light. Solar cells are the building blocks of photovoltaic modules, otherwise known as solar panels.

Based on Solar Cell structure, various equipment are used in manufacturing process. Main Equipment are Texturing, Diffusion POCL3, PSG Etching, Edge Isolation, PECVD, Screen Printing etc.

This equipment is used for chemical corrosion, cleaning and drying of mono/multi-crystalline solar wafers.

**Processing Steps:**  
- Loading→Texturing→DI water spraying 1→Alkaline cleaning→DI water
- spraying 2→ Acid cleaning→ DI water spraying 3 →Drying→ Unloading

Inline Texturing Machine for multicrystalline wafers

Mainly used for forming PN junction of diffusion doping of silicon wafer in the manufacturing process of crystalline silicon solar cell.

**Process Flow:** prepare quartz boat & wafers→insert wafers→loading→chose process→boat in→vacuumize →stable temperature increase→oxygen in→power on→put in→constant temperature→boat out→boat unloading and cooling→testing→wafers unloading
