Problems solved by technology

It is impossible to realize a self-generating hydrogen device for photo-splitting water without external electrical energy in the true sense
At the same time, there are still some disadvantages such as low utilization rate of visible light and low photoelectric conversion efficiency of some materials. Most materials can only absorb ultraviolet light, and ultraviolet light only accounts for 3% of sunlight.
e.g. TiO 2 Photowater splitting devices as anode materials, due to TiO 2 The band gap is wide, and it can only absorb the ultraviolet

Embodiment Construction

[0027] Hereinafter, the present invention will be described in further detail with reference to the accompanying drawings.

[0028] The preparation of CZTS solar cell, it comprises,

[0029] The preparation method of CZTS absorption layer in CZTS solar cell:

[0030] CZTS films were prepared by electrodeposition followed by sulfuration annealing. An electrochemical workstation was used for electrodeposition, and the electrode system used was a three-electrode device consisting of an Ag / AgCl reference electrode, a Pt counter electrode, and a working electrode on a molybdenum-coated glass substrate. Concretely comprise following preparation steps:

[0031] First, deposit the copper layer, the deposition potential of the copper layer is -0.3V~-0.5V (relative to the Ag / AgCl reference electrode), and the electroplating solution is 0.03mol / L~0.06mol / L CuSO 4 ·5H 2 O, prepared from 0.01mol / L~0.03mol / L citric acid and 0.03mol / L~0.06mol / L sodium citrate.

[0032] Carry out the dep...

Abstract

The invention relates to a sunshine water decomposition hydrogen generation microelectronic device and a preparation method thereof. The sunshine water decomposition hydrogen generation microelectronic device comprises a CZTS solar cell, a BiVO<4> photo anode, a wire and a Pt sheet, wherein the CZTS solar cell, the BiVO<4> photo anode and the Pt sheet are connected through the wire to realize thesemiconductor device without external bias voltage and with a series structure for performing hydrogen making through photocatalytic water splitting; without an extra power supply, sunshine is utilized directly to realize automatic hydrogen making through photocatalytic water splitting, so that all source of the hydrogen energy is sunshine; and the sunshine direct power generation is stable, toxic-free, low in cost of raw materials, and real cleaning, low-cost, environmental protection and environment friendly hydrogen making can be realized, and the produced hydrogen renewable.

Description

technical field [0001] The invention relates to the field of water splitting by sunlight, in particular to a microelectronic device for hydrogen production by splitting water by sunlight and a preparation method thereof. Background technique [0002] With the progress and development of human society, the demand for energy is becoming increasingly urgent. At the same time, the combustion products produced during the combustion of non-renewable energy such as coal and petroleum will cause irreversible pollution to the environment. Therefore, it is particularly important for the development of clean energy. As a new type of environmentally friendly and renewable clean energy, hydrogen energy is considered to be one of the most ideal energy sources in the new century due to its high energy content, green environmental protection and other advantages. At present, the existing photohydrolysis devices are unstable, high in cost, and easy to cause pollution to the environment. A...
