Therefore, by dismantling the frame structure of waste photovoltaic devices and removing the EVA film and tempered glass packaging layer on the surface of the device; then connecting them in series appropriately according to the degree of damage of the photovoltaic cell device and the voltage parameters, and then packaging them with conductive glass, finally loading catalysts on both sides of the conductive glass, the photovoltaic module can be converted into a photoelectric catalytic device.

[0003] However, there are some problems with the existing technology: the existing photoelectrocatalytic water splitting device directly places the photoelectrocatalytic component modified from the photovoltaic device in the reaction tank to complete the photoelectrocatalytic reaction under sunlight irradiation. However, the area of ​​the photoelectrocatalytic component is limited, so the sunlight received is limited, and the photoelectrocatalytic efficiency is low. Therefore, we propose a concentrated photoelectrocatalytic water splitting device based on the modification of the photovoltaic device. Utility Model Content

[0022] To further understand the content, features and effects of the present utility model, the following embodiments are exemplified and described in detail with reference to the accompanying drawings as follows.

[0023] As Figures 1 to 6 shown, a condensing photoelectrocatalytic water splitting device based on the modification of a photovoltaic device provided by an embodiment of the present utility model includes a base 1. The base 1 is rectangular and made of stainless steel material. The main function of the base 1 is to support the entire device.

[0024] A reaction tank 2 is fixedly connected to the middle of the base 1. The reaction tank 2 is rectangular and made of transparent glass material. Its main function is to provide a reaction space for photoelectrocatalysis. A frame 10 is fixedly connected to the inner wall of the reaction tank 2. A photoelectrocatalytic assembly 3 is arranged inside the frame 10. The photoelectrocatalytic assembly 3 includes a battery panel 301. Both sides of the battery panel 301 are fixedly connected with conductive glass 302. A positive electrode catalytic layer 303 and a negative electrode catalytic layer 304 are respectively fixedly connected to one side of the two groups of conductive glass 302. The battery panel 301, the conductive glass 302, the positive electrode catalytic layer 303 and the negative electrode catalytic layer 304 are all wrapped inside the frame 10.

[0025] The photoelectrocatalytic assembly 3 is modified from a waste photovoltaic device. First, disassemble the frame structure of the waste photovoltaic device and remove the EVA film and tempered glass encapsulation layer on the surface of the device; then appropriately connect it in series according to the damage degree and voltage parameters of the photovoltaic cell device to meet the thermodynamic and kinetic requirements of different application scenarios such as photoelectrochemical water splitting or photoelectrochemical carbon dioxide reduction, and then encapsulate it with conductive glass 302. Finally, load the positive electrode catalytic layer 303 and the negative electrode catalytic layer 304 on both sides of the conductive glass 302.

[0026] A proton exchange membrane 4 is fixedly connected to the middle of the inner wall of the reaction tank 2. The proton exchange membrane 4 and the photoelectrocatalytic assembly 3 divide the reaction tank 2 into two parts, so that one part of the reaction tank 2 generates oxygen and the other part generates hydrogen, effectively avoiding potential safety problems caused by gas mixing.

[0027] A top cover 5 is detachably connected to the upper end of the reaction tank 2, and the top cover 5 can be removed to clean the reaction tank 2 or replace and repair its internal components. Fixed plates 6 are slidably connected to both sides of the base 1. Slideways are provided at both ends of the base 1, and the fixed plates 6 are slidably connected within the slideways. Motors 11 are fixedly connected to both ends of the base 1, and the output ends of the motors 11 are fixedly connected to threaded rods 12. The threaded rods 12 are rotatably connected to the inner walls of the slideways, and the motors 11 are electrically connected to the photosensitive sensors 17.

[0028] Threaded holes are provided at the bottom ends of the fixed plates 6, and the threaded rods 12 are rotatably connected within the threaded holes. The threaded rods 12 can drive the fixed plates 6 to slide within the slideways of the base 1.

[0029] After the motors 11 rotate, they will drive the threaded rods 12 to rotate. After the threaded rods 12 rotate, the fixed plates 6 will slide within the slideways of the base 1, so that the distance between the condenser lens 9 and the photoelectrocatalytic assembly 3 can be adjusted. The position of the condenser lens 9 can be changed according to the sunlight intensity, so that more sunlight can be concentrated on the photoelectrocatalytic assembly 3, accelerating the rate of the photoelectrocatalytic reaction.

[0030] The fixed plates 6 are movably connected to fixing frames 7, and adjusting assemblies 8 are provided on the fixed plates 6. The adjusting assemblies 8 are used to adjust the fixing frames 7. The adjusting assemblies 8 include hydraulic rods 801. The hydraulic rods 801 are fixedly connected to one side of the fixed plates 6.

The fixing frames 7 are fixedly connected to the fixing blocks 802, and the hydraulic rods 801 are electrically connected to the photosensitive sensors 17.

[0031] When the hydraulic rods 801 extend and retract, they will drive the fixing blocks 802 to move, and the fixing blocks 802 will drive the fixing frames 7 to move, so that the condenser lens 9 on the fixing frames 7 can adjust its own angle according to the irradiation angle of the sunlight, so that more sunlight is concentrated on the photoelectrocatalytic assembly 3, accelerating the light-end catalytic rate.

[0032] The condenser lens 9 is detachably connected to the fixing frames 7. A number of photosensitive sensors 17 are fixedly connected around the fixing frames 7. The photosensitive sensors 17 are used to detect the sunlight intensity, so as to control the motors 11 and the hydraulic rods 801 to adjust the angle and position of the condenser lens 9 through the detected data, so that the condenser lens 9 can concentrate more sunlight on the photoelectrocatalytic assembly 3, accelerating the rate of the photoelectrocatalytic reaction.

[0033] A water inlet 13 is fixedly connected to the upper end of one side of the reaction tank 2. The water inlet 13 is used to add water to be electrolyzed into the reaction tank 2. A drain outlet 14 is fixedly connected to the lower end of the other side of the reaction tank 2. The drain outlet 14 is used to drain the water in the reaction tank 2 to clean and change the water in the reaction tank 2. An oxygen discharge port 15 and a hydrogen discharge port 16 are fixedly connected to the upper end of the top cover 5. The oxygen discharge port 15 and the hydrogen discharge port 16 are used to discharge the oxygen and hydrogen generated during the reaction.

[0034] The working principle of the present utility model is as follows:

[0035] The present utility model is provided with a condenser lens 9, which can concentrate sunlight through the condenser lens 9, so that more sunlight can shine on the surface of the photoelectrocatalytic component 3, improving the efficiency of photoelectrocatalysis.

[0036] The present utility model is fixedly connected with a plurality of photosensitive sensors 17 around the fixing frame 7. The photosensitive sensors 17 can detect the intensity of sunlight, thereby controlling the telescopic movement of the hydraulic rod 801 according to the intensity of sunlight, so as to change the angle of the condenser lens 9, enabling the condenser lens 9 to reflect stronger sunlight. At the same time, the motor 11 will start to drive the threaded rod 12 to rotate, causing the fixing plate 6 to slide in the slideway on the base 1, adjusting the distance between the condenser lens 9 and the photoelectrocatalytic component 3, so that sunlight can be better concentrated and irradiated on the surface of the photoelectrocatalytic component 3, accelerating the rate of the photoelectrocatalytic reaction.
