quality Ball Wafer Production Line products performance parameters
Time: 2023-01
quality Ball Wafer Production Line products and silicon solar cells are typical representatives of semiconductor materials and semiconductor devices, respectively. Semiconductor characteristic parameters measure and characterize the performance of materials and their devices. Since carriers are the functional carriers of semiconductor materials and devices, the movement of carriers forms current and electric field, and the carriers have characteristics such as light emission and thermal radiation, so the carrier parameters are used to characterize the carrier transport of semiconductor materials and devices. The basis of the characteristics, namely the carrier parameters, is an important part of the characteristic parameters of silicon wafers and silicon solar cells.
When the quality Ball Wafer Production Line products are processed and manufactured to form a silicon solar cell, due to the difference between the pn junction and the Fermi level, the carriers are separated to form a voltage, and then have electrical properties such as saturation current, fill factor, and photoelectric conversion efficiency. The parameters intuitively reflect and affect the volt-ampere characteristics of solar cells. In summary, the main characteristic parameters of quality Ball Wafer Production Line products include carrier parameters.
quality Ball Wafer Production Line products Carriers are divided into majority carriers and minority carriers, including electrons and holes. Carrier diffusion and drift form the basis of information transmission in semiconductor devices. Carrier transport parameters are the basic parameters to describe the movement and concentration of carriers, mainly including carrier lifetime, diffusion coefficient and front and back surface recombination rate, etc.
