SOLAR CELL

摘要

PURPOSE: A solar cell is provided to improve the photoelectric conversion efficiency of the solar cell using a substrate including a first region that is a single crystal silicon region and a second region that is a polycrystalline silicon region. CONSTITUTION: A first conductive type impurity is coated on a substrate. A second conductive type impurity is coated on an emitter part. An antireflection unit(130) is located on the upper side of the emitter part. A front electrode unit(150) is electrically connected to the emitter part. A rear electrode unit(160) is electrically connected to the substrate.
