String welding of solar cells The operation process is as follows: Arrange the specified number of welded cells on the template with the back facing upward, and lightly press the two cells with one hand to make them stick to the heating template and close to each other.
A solar cell fabrication process uses several high-temperature steps including a phosphorus diffusion process and a metal contact firing. The silicon wafer is p-type doped to 1 · 10 15 cm −3. The required surface doping and depth for the diffused part of the pn junction are 1 · 10 19 cm −3 and 200 nm, respectively.
Constant-source and constant-dose diffusion are the most common in silicon solar cell fabrication. Typical processes to form the pn junction in silicon solar cells comprise two steps: A pre-deposition process with a constant source, such as process A defined previously, to introduce the desired dose of dopant impurities in the wafer surface.
Working Principle: The working of solar cells involves light photons creating electron-hole pairs at the p-n junction, generating a voltage capable of driving a current across a connected load.
Screen-printed solar cells typically use a simple homogeneous diffusion to form the emitter where the doping is the same beneath the metal contacts and between the fingers. To maintain low contact resistance, a high surface concentration of phosphorus is required below the screen-printed contact.
