Passivation layer solar cell
WebThe major drawback when using a-Si passivation layers in crystalline silicon solar cell technology is the relatively low thermal stability of the passivation properties. After a typical screen printed contact firing step with temperatures of up to ∼850 ° C the passivation properties are strongly reduced [ 24 ]. WebSurface passivation The surfaces of solar cells are an important multifunctional interface, critical to solar device operation. At the surface of a semiconductor, the periodicity of the atomic lattice ends, and atoms at the surface lack sufficient neighbours to bond with.
