Abstract
The photovoltaic cell includes a silicon substrate, a first passivation layer, a second passivation layer, at least one silicon oxynitride layer, and at least one silicon nitride layer. The second passivation layer includes a first silicon oxide layer and at least one aluminum oxide layer, and a thickness of the at least one aluminum oxide layer is in a range of 4 nm to 20 nm. The number of silicon atoms is greater than the number of oxygen atoms in the at least one silicon oxynitride layer and the number of oxygen atoms is greater than the number of nitride atoms in the at least one silicon oxynitride layer. The first silicon oxide layer is disposed between the substrate and the at least one aluminum oxide layer, and a thickness of the first silicon oxide layer is in a range of 0.1 nm to 5 nm.
