SOLAR CELL, CAPABLE OF PREVENTING CRYSTALLIZATION OF AN AMORPHOUS SILICON LAYER BY INSERTING A METAL BUFFER LAYER BETWEEN THE AMORPHOUS SILICON LAYER AND A TRANSPARENT ELECTRODE

摘要

PURPOSE: A solar cell is provided to improve photoelectric conversion efficiency by lowering the reflexibility of the solar cell by suppressing the reflection of the incident light from the outside.;CONSTITUTION: A solar battery includes an n type or p type amorphous silicon layer, a transparent electrode(120) and a metal buffer layer(130). The metal buffer layer is arranged between the transparent electrode and the amorphous silicon layer. The metal buffer layer is made of In, Sn, B, Al, Ga, or Zn and is equal to or thinner than the transparent electrode.;COPYRIGHT KIPO 2010
