Patent ID: 11545590

Abstract:
A solar cell, a method for producing a solar cell, and a solar module are provided. The solar cell includes: an N-type substrate and a P-type emitter formed on a front surface of the substrate; a first passivation layer, a second passivation layer and a third passivation layer sequentially formed over the front surface of the substrate and in a direction away from the P-type emitter, and a passivated contact structure disposed on a rear surface of the substrate. The first passivation layer includes a first Silicon oxynitride (SiOxNy) material, where x>y. The second passivation layer includes a first silicon nitride (SimNn) material, where m>n. The third passivation layer includes a second silicon oxynitride (SiOiNj) material, where a ratio of i/j∈[0.97, 7.58].
