Product Description
Solar Cell Production Line
Cleaning &Texturing: Wafers undergo a meticulous cleaning process using industrial soaps to form square-based pyramids, also known as texture. This texturization significantly reduces sunlight reflection, thereby enhancing the overall efficiency of the solar cells.
Diffusion: Initially pre-doped with boron during casting, the wafers are then endowed with a negative (n-type) surface characteristic via high-temperature diffusion using a phosphorus source. This vital step creates the essential negative/positive (n-p) junction.
Etching : During the phosphorus diffusion stage, undesired PN junctions may develop on the wafer sides and opposite surface, leading to shunt paths between the cell's front and rear. These paths are meticulously removed through etching, effectively isolating the edge/junction.
PECVD : Utilizing PECVD equipment, the wafers receive an anti-reflection coating (ARC) of blue silicon nitride film. This coating is crucial for minimizing reflection and maximizing light absorption, significantly boosting cell efficiency.
Printing & Heating: Electrodes on the silicon solar cells are precisely printed using advanced screen technology, ensuring an optimal ohmic contact for superior performance.
Testing & Sorting: Each cell undergoes rigorous testing under simulated sunlight conditions to classify them based on their efficiency, ensuring only the best cells are used in our modules.
