Fire the cell to drive the silver through silicon nitride in front of the cell, and alloy aluminum on the back of the cell to form a metal/p+ contact. Both monocrystalline and polycrystalline solar panels have cells made of silicon wafers. Overall, it has been observed that Fresnel mirror concentrator is more efficient than cylindrical parabolic concentrator. The interest in gettering phenomenon stems from the fact that metallic complexes/precipitates within the depletion regions of functional junction devices generate larger leakage currents and cause lower junction breakdown voltage. In the laboratory, efficiencies on monocrystalline silicon above 25 % will be reached. However, when these materials were used, the open-circuit voltage change was accompanied by an increase in the short-circuit current density; this behavior has been attributed to the dependence of the hole mobility of this medium on the operating temperature [56,57]. Since 1975, process and equipment for the screen-printed solar cell has been further optimized and new technologies Reprinted with permission from M. Bavarian, S. Nejati, K.K.S. Nazek El-Atab.
