Embodiment Construction
[0011] The present invention will be further described below in conjunction with the accompanying drawings.
[0012] like figure 1 Shown, the present invention is a kind of absorber film that is used for thermal photovoltaic cell, comprises graphene layer 2, Au layer 3, Ag layer 4, PMMA layer 5, is characterized in that: in described Au layer 3 and Ag layer 4 There is a graphene layer 2 in the middle, a graphene layer 2 on the lower surface of the Au layer 3, a PMMA layer 5 on the upper surface of the Ag layer 4, and the Ag layer 4 is composed of a plurality of hemispherical Ag particles 6.
[0013] The thickness of the Au layer 3 is 5-20 nanometers.
[0014] The diameter of the hemispherical Ag particles 6 is 10-15 nanometers.
[0015] The thickness of the PMMA layer 5 is 90-100 nanometers.
[0016] The present invention obtains through the following steps:
[0017] (1) Clean the thermal photovoltaic cell substrate 1 with alcohol, one end of the thermal photovoltaic cell ...
