Embodiment Construction
[0034] In order to make the content of the present invention more clearly understood, the present invention will be further described in detail below based on the embodiments and in conjunction with the accompanying drawings.
[0035] Such as figure 1 As shown, the method for applying the present invention to improve the photoelectric performance of heterojunction solar cells includes:
[0036] (a) performing damage removal and surface texturing on the N-type single crystal silicon substrate layer;
[0037] (b) depositing an intrinsic amorphous silicon film on both sides of the N-type single crystal silicon substrate layer;
[0038] (c) Depositing a P-type amorphous silicon film and an N-type amorphous silicon film on the two surfaces where the intrinsic amorphous silicon film is deposited;
[0039] (d) depositing a tin-doped indium oxide transparent conductive film on the surface of the P-type amorphous silicon film;
[0040] (e) depositing a tin-doped indium oxide transpa...
