Thin film solar cell production method and electrodeposition device thereof

[0075] Example 1

[0076] Figure 1a-2p The method for producing the thin-film solar cell 1 in this embodiment is shown, including the following steps:

[0077] (A) Depositing a transparent conductive layer 12 (Transparent conductive oxide, TCO for short) on the glass substrate 11;

[0078] (B) A window layer 13 is formed on the transparent conductive layer 12. In this embodiment, the window layer 13 is cadmium sulfide (CdS), and the window layer 13 is formed on the transparent conductive layer 12 by electrodeposition;

[0079] (C) The contact electrode 2 penetrates the window layer 13 to make ohmic contact with the transparent conductive layer 12, and the above-mentioned semi-finished product is placed in the electrodeposition tank, and the contact electrode 2 and the counter electrode are energized, in the window layer 13. Electrodeposit an absorption layer 14 on the electrode. The absorption layer 14 is cadmium telluride (CdTe). In this embodiment, the cross section of the contact ele
