Title:
SOLAR CELL
Document Type and Number:
WIPO Patent Application WO/2018/169207
Kind Code:
A1
Abstract:
A solar cell capable of improving light utilization efficiency is disclosed. The solar cell comprises an I-VII group compound photovoltaic layer, a silicon photovoltaic layer, a first electrode, and a second electrode. The I-VII group compound photovoltaic layer includes a first-type I-VII group compound layer and a second-type I-VII group compound layer. The first-type I-VII group compound layer includes first-type impurities. The second-type I-VII group compound layer is formed on the lower part of the first-type I-VII group compound layer, and includes second-type impurities for forming a polarity opposite to that of the first-type impurities. The silicon photovoltaic layer includes a first-type silicon layer and a second-type silicon layer. The first-type silicon layer is formed on the lower part of the second-type I-VII group compound layer, and includes a first-type dopant. The second-type silicon layer is formed on the lower part of the first-type silicon layer, and includes a second-type dopant for forming a polarity opposite to that of the first-type dopant. The first electrode is formed on the lower part of the second-type silicon layer. The second electrode is formed so as to expose the first-type I-VII group compound layer to the upper part of the first-type I-VII group compound layer.
