Polycrystalline silicon (poly-Si) is widely applied to make low-cost, highly efficient, and large-area solar cells. However, poly-Si involves electrically active states that deteriorate the conversion efficiency of solar cells. [1, 2] Note that in band gap the electrical activity of grain boundary depends on the atomic structure of grain boundary since the dangling-bonds or extra bonds generates deep-level states in the band gap.
