Abstract: A solar cell includes a substrate, an emitter region positioned at a first surface of the substrate, a first electrode positioned on the first surface of the substrate, a back passivation layer positioned on a second surface opposite the first surface of the substrate, and a second electrode which is positioned on the back passivation layer and is electrically connected to the substrate through holes of the back passivation layer. The second electrode includes connection electrodes positioned inside the holes of the back passivation layer and a back electrode layer positioned on the connection electrodes and the back passivation layer. An adhesion enhanced layer is positioned between the back electrode layer and the back passivation layer and contains at least one of intrinsic amorphous silicon and intrinsic microcrystalline silicon.

Abstract: A solar cell includes a semiconductor substrate having a first conductivity type, an emitter layer on a surface of the semiconductor substrate, the emitter layer having a second conductivity type different from the first conductivity type, and electrodes including a first electrode electrically connected to the emitter layer, and a second electrode electrically connected to the semiconductor substrate. The emitter layer includes a high-concentration doping portion adjacent to the first electrode, and a low-concentration doping portion in a region that does not include the high-concentration doping portion. The low-concentration doping portion has a higher resistance than the high-concentration doping portion. The high-concentration doping portion includes a first region having a first resistance, and a second region having a second resistance higher than the first resistance.
