Abstract
Disclosed are a method for manufacturing a thin-film type solar cell and a thin-film type solar cell obtained thereby that uses a direct printing method and reduces the frequency of a cutting process.
Claims19
A method for manufacturing a thin-film solar cell, comprising:
- forming a lower transparent electrode layer, a semiconductor layer for photoelectric conversion, and an upper transparent electrode layer on a substrate;
- cutting through portions of the lower transparent electrode layer, the semiconductor layer for photoelectric conversion, and the upper transparent electrode layer, so that a plurality of cells are patterned, and portions of the substrate and other portions of the lower transparent electrode layer are exposed;
- forming an insulating layer on the plurality of cells so that respective portions of the insulating layer extend between a lower transparent electrode layer and an upper transparent electrode layer of each of the plurality of cells;
- and
- forming a rear electrode layer on the plurality of cells so that respective portions of the rear electrode layer extend to connect an upper transparent electrode layer of one of the plurality of cells to a lower transparent electrode layer of an adjacent another of the plurality of cells in series.

A method for manufacturing a thin-film solar cell, comprising:
- cutting through portions of a lower transparent electrode layer formed on a substrate to pattern the lower transparent electrode layer;
- sequentially forming a semiconductor layer for photoelectric conversion and an upper transparent electrode layer on the patterned lower transparent electrode layer;
- cutting through portions of the semiconductor layer for photoelectric conversion and the transparent electrode layer, so that a plurality of cells are patterned, and portions of the lower transparent electrode layer are exposed;
- and
- forming a rear electrode layer on the plurality of cells so that respective portions of the rear electrode layer extend to connect an upper transparent electrode layer of one of the plurality of cells and a portion of an exposed lower transparent electrode layer of an adjacent another of the plurality of cells in series.
2 more elements
A thin-film solar cell including a plurality of cells, the thin-film solar cell comprising:
- a substrate;
- and
- a lower transparent layer, a semiconductor layer for photoelectric conversion, an upper transparent layer, and a rear electrode layer that are sequentially formed on the substrate, wherein respective portions of the rear electrode layer extend from an upper surface of the upper transparent electrode layer of one of the plurality of cells to a lower transparent electrode layer of an adjacent another of the plurality of cells in series.
