Abstract
A solar cell includes a semi-conductive substrate, a doping layer, an anti-reflection layer, an electrode, a passivation stacked layer and a contact layer. The semi-conductive substrate has a front and a back surface. The doping layer is disposed on the front surface. The anti-reflection layer is disposed on the doping layer. The electrode is disposed on the anti-reflection layer and electrically connected to the doping layer. The passivation stacked layer is disposed on the back surface and has a first dielectric layer, a second dielectric layer and a middle dielectric layer sandwiched between the first and the second dielectric layer. The dielectric constant of the middle dielectric layer is substantially lower than the dielectric constant of the first dielectric layer and the dielectric constant of the second dielectric layer. The contact layer covers the passivation stacked layer and electrically contacts with the back surface of the semi-conductive substrate.
