SOLAR CELL AND SOLAR MODULE INCLUDING THE SAME

摘要

A solar cell includes a substrate having an incident surface and a back surface, an emitter layer formed on the incident surface, an anti-reflective layer formed on the emitter layer opposite to the substrate, a passivation unit formed on the back surface of the substrate, a plurality of metallic nanoparticles capable of reflecting light and disposed in the passivation unit, a first electrode disposed on and electrically connected to the emitter layer, and a second electrode disposed on the passivation unit and electrically connected to the substrate. A solar module including the aforesaid solar cell is also disclosed.

主权项

1. A solar cell, comprising:
a substrate of a first conductivity type, said substrate having an incident surface and a back surface opposite to said incident surface; an emitter layer that is formed on said incident surface of said substrate and that has a second conductivity type different from the first conductivity type of said substrate; an anti-reflective layer formed on said emitter layer opposite to said substrate; a passivation unit that is formed on said back surface of said substrate; a plurality of metallic nanoparticles that are capable of reflecting light and that are disposed in said passivation unit; a first electrode disposed on and electrically connected to said emitter layer; and a second electrode disposed on said passivation unit and electrically connected to said substrate.
