Embodiment Construction

[0023] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below. All other implementations obtained below fall within the protection scope of the present invention.

[0024] The present invention will be further described below in conjunction with accompanying drawing.

[0025] Such as figure 1 As shown, the flexible transparent functional device 10 includes electrode layers (1, 2), energy collection and conversion layer 3 and protective layers (upper surface protective layer 5, lower surface protective layer 6). The energy collection and conversion layer 3 is located above the electrode layer and can form ohmic contact with it, and the protective layers (5, 6) are respectively arranged on the outer surfaces of the energy collection and conversion layer 3 and the electrode layer.

[0026] In a specific embodiment, the electrode layer is base...

Abstract

The invention provides a flexible transparent functional device, which includes an electrode layer, an energy collection and conversion layer and a protective layer. The energy collection and conversion layer is located above the electrode layer and can form ohmic contact therewith, and the protective layer is bonded to the upper and lower sides of the electrode layer. The electrode layer takes mica sheet as the substrate. By selecting mica sheet as the substrate of the electrode layer, the invention solves the problem that high temperature annealing and alloying process can be used between the inorganic material and the electrode layer to realize ohmic contact when the inorganic material is used as the energy collection and conversion layer; meanwhile, the function of the device is guaranteed. Overall flexibility and optical clarity.

Description

technical field [0001] The invention relates to the technical field of intelligent materials and micro-nano device processing, in particular to a flexible and transparent micro-functional device and a preparation method thereof. Background technique [0002] As we all know, there are various forms of energy in nature, such as: thermal energy, light energy, mechanical energy and chemical energy, etc., many of which can be used as energy available to human beings. Since various forms of energy can be transformed and recycled, some researchers have proposed the concept of energy harvesting. [0003] At present, from the perspective of microscopic applications, with the continuous progress of integrated circuit technology and micro-electromechanical system (MEMS) technology, many traditional devices are developing towards miniaturization and low power consumption. Therefore, the study of micro-energy harvesting technology to power some low-power electronic devices has become a ...
