Embodiment Construction

[0032] The method for manufacturing a thin-film solar cell stack and the embodiments of the thin-film solar cells according to the present invention will be described below with reference to the relevant drawings. For ease of understanding, the same components in the following embodiments are described with the same symbols.

[0033] see figure 1 , which is a schematic structural view of the first embodiment of the thin film solar cell of the present invention. As shown in the figure, the thin film solar cell includes a substrate 10, an amorphous silicon layer (Amorphous Silicon Layer, a-Silayer / Cell) 11, a first conductivity type layer 12, an intrinsic type stacked layer 13, a second conductivity type layer 14 and back electrode layer 15 . One side of the substrate 10 is the illuminating surface, and the substrate 10 can be a rigid substrate or a flexible substrate. The rigid substrate is, for example, a glass substrate used as a curtain of a building; the flexible substrate...

Abstract

The invention discloses a manufacturing method of thin film solar cells and the thin film solar cells thereof. The thin film solar cells comprise a substrate, an amorphous silicon layer, a first conductive layer, a stacked I-layer, a second conductive layer and a back contact layer. The amorphous silicon layer is on the substrate. The first conductive layer is on the amorphous silicon layer. The stacked I-layer is on the first conductive layer; the stacked I-layer from bottom to top is sequentially stacked by three different deposition rate I-layers: a first I-layer, a second I-layer and a third I-layer. Compared with the first and the third I-layer, the second I-layer has deposition rate higher than those of the other two I-layers. The second conductive layer is on the stacked I-layer. The back contact layer is on the second conductive layer for getting electric energy.

Description

technical field [0001] The present invention relates to a solar cell manufacturing method and the thin film solar cell, in particular to a thin film solar cell stack manufacturing method and the thin film solar cell which can improve mass production speed and electric energy efficiency. Background technique [0002] At present, due to the international energy shortage, countries around the world have been continuously researching and developing various feasible alternative energy sources, and among them, solar cells that generate electricity from solar energy have attracted the most attention. Solar cells are easy to use, inexhaustible, inexhaustible, and no waste. It has the advantages of no pollution, no rotating parts, no noise, can block radiant heat, long service life, size can be changed at will, and it can be combined with buildings and popularized, so solar cells are used as energy sources. [0003] In the 1970s, silicon solar cells first developed by Bell Laboratori...
