THIN FILM TYPE SOLAR CELLS CAPABLE OF IMPROVING LIGHT USAGE EFFICIENCY AND A MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A thin film type solar cells and a manufacturing method thereof are provided to increase internal reflection by using an n-type silicon alloy reflection layer as an n-type layer.;CONSTITUTION: A front transparent electrode(20) is laminated on a substrate. A cell(30) is laminated on the front transparent electrode. A back electrode(40) is laminated on the cell. The cell includes a p-type window layer(31), an i-type photoelectric conversion layer(32), and an n-type layer(33). The n-type layer includes an n-type silicon alloy reflection layer having a low refractive index element.;COPYRIGHT KIPO 2013
