Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring first to fig. 1, fig. 1 illustrates a singulation process. The whole battery piece 1 is divided into a plurality of independent battery pieces 1 '/1' ″ … …; wherein, the separated side of two adjacent battery pieces is the fracture end of the battery piece. Therefore, the fracture end is a fracture position formed after the whole battery piece 1 is divided; since the position is cut, the inside of the entire cell piece 1 is exposed; although the exposed part of the cut end is also oxidized naturally, the formed oxide layer has insufficient passivation degree and high molecular activity, and the photoelectric conversion efficiency of the cell is reduced.
Therefore, the application discloses a battery piece preparation process, at least passivating the opening end of a battery piece to form an insulating layer at the opening end of the battery piece; through the formation of the insulating layer, the position of the opening of the battery piece is passivated, so that a dangling key is removed, the surface state is reduced, the power loss of the battery piece is reduced, and the reliability of the battery piece is improved.
Specifically, referring to fig. 2, the preparation process of the battery piece comprises the following steps: scribing the surface of the whole cell 1 by laser; breaking the whole cell slice 1 along the scribing line, so that the whole cell slice is divided into a plurality of cell slices 1 '/1'; the battery piece 1 '/1' is passivated, so that the insulating layer 2 is formed at the segment mouth end of the battery.
It is easy to understand that when the whole battery piece 1 is directly divided, the fracture ends are easily uneven, and the dividing quality cannot be guaranteed. Before splitting the whole cell piece 1, scribing the surface of the whole cell piece 1 by laser to form a dividing line 3; dividing the whole battery slice 1 into a plurality of battery slices 1 '/1' meeting the specification through a dividing line 3; the whole cell sheet 1 is divided along the dividing line 3 to obtain the desired cell sheet 1'/1 ".
Further, as for the passivation treatment, two ways can be generally adopted; one is an electroless plating film, for example, deposited by thermal oxidation, laughing gas oxidation, ozonization or nitric acid solution chemical method, thereby forming a SiO2 film layer at the fracture; for example, the film layer may be formed by PECVD (Plasma Enhanced Chemical Vapor Deposition), CVD (Chemical Vapor Deposition) or PVD (Physical Vapor Deposition) method to form Al2O3 film layer or containing Al2O3Or alternatively, deposited by the method of A L D.
It should be explained that, when a PECVD or CVD deposition process is used, the cell is sintered, the process temperature is high, and the silver paste on the surface of the cell is damaged by high temperature.
To this end, in one embodiment, the passivation process employs an a L D deposition technique.
Specifically, Atomic layer Deposition (A L D) is a surface chemical vapor Deposition-based nano-film Deposition technique that can deposit a material as a monoatomic film on a substrate surface by separately introducing two or more chemical sources into a reaction chamber while purging a vapor reaction product and an unreacted gas after a surface saturation reaction, thereby precisely controlling the thickness and uniformity of the deposited film within an Atomic layer thickness range, and SiO is manufactured by Atomic layer Deposition (A L D) and plasma Atomic layer Deposition (PEA L D)2、Al2O3And nano laminated layers and composite materials of SiNx and the like, thereby passivating the cut-off end, prolonging the minority carrier lifetime and improving the photoelectric conversion efficiency of the cell.
More specifically, using the a L D deposition technique, the cell 1'/1 "was placed in the a L D reaction chamber and the chemical source material was carried out by inert gas to react chemically at the cell segment open end to form the insulating layer 2.
The chemical source material is used for providing a silicon source, an aluminum source and/or an oxygen source, the relevant chemical source material is pulsed in an A L D reaction chamber according to the temperature and the vacuum degree required by the process, then inert gas is used for cleaning, and finally a composite film with the required thickness is formed at the opening end of the cell fragment through multiple times of pulsing and cleaning, namely the insulating layer 2 is formed.
It should be added that the passivation treatment can be performed on the battery segment opening end, for example, only the battery segment opening end is placed in the a L D reaction chamber for passivation treatment, or the whole battery piece is processed, for example, the battery piece is directly placed in the a L D reaction chamber for passivation operation, and the insulating layer 2 can be formed on the battery segment opening end.
Furthermore, the whole cell piece 1 is split to form a small cell piece with a fracture end, the fracture end is not flat, and based on the characteristic of A L D growth, the formed composite insulating layer 2 can be better coated on the surface of a complex structure, so that the connection position of the fracture end and the surrounding interface is further ensured to be coated, a good insulating layer 2 is formed, and the passivation effect is ensured.
For the passivation treatment, another embodiment is to directly coat the insulating layer 2 at the open end of the battery segment. For example, the insulating material is directly sprayed to the opening end of the battery segment to constitute the insulating layer 2.
Specifically, after the whole battery piece 1 is divided into a plurality of small battery pieces, an insulating material (e.g., an insulating varnish, or an insulating plastic, or an insulating film) may be sprayed or applied to the battery piece opening end, thereby forming the insulating layer 2 at the battery piece opening end.
The application also discloses a battery piece preparation device, which can realize the battery piece preparation process; the battery piece preparation facilities includes: the scribing mechanism 10 is used for scribing the surface of the whole battery piece 1; the sheet breaking mechanism 20 is arranged at the downstream of the scribing mechanism 10 and can break the whole cell sheet 1 along the scribing line; and a passivation mechanism 30 provided downstream of the sheet severing mechanism 20 and capable of passivating the severed cells 1'/1 ″.
With particular reference to fig. 3, the scribing mechanism 10 comprises: the bearing table 11 is used for bearing the whole battery piece 1; the laser device 12 has a working end facing the carrier 11 and can emit laser to scribe the entire cell 1 on the carrier 11. The whole battery piece 1 is placed on a bearing platform 11 and is delivered to the position below the laser device 12 by the bearing platform 11; the laser device 12 emits laser light to scribe the dividing lines 3 on the entire battery piece 1 by a predetermined stroke, thereby dividing the entire battery piece 1 into a plurality of small pieces.
The laser device 12 comprises a laser emitter and a laser driving component, wherein the laser driving component is connected with the laser emitter and can drive the laser emitter to move along the vertical and/or horizontal direction, so that the laser emitter can be controlled to mark a required dividing line 3 on the whole cell piece 1 along a preset track. Specifically, the laser driving assembly can be provided with a plurality of groups of linear driving mechanisms (for example, driving members such as an electric cylinder or a linear module are adopted) according to the requirement of a preset track, so that the laser transmitter can be driven to move as required.
In addition, in order to ensure the stability of laser scribing, the bearing table 11 can be provided with air holes and air extraction equipment communicated with the outside; therefore, after the whole battery piece 1 is arranged on the bearing platform 11, the air extraction equipment can vacuumize the inside of the bearing platform 11 to form negative pressure inside the bearing platform 11, so as to further absorb the whole battery piece 1 and prevent the whole battery piece 1 from displacing.
Further, the scribing mechanism 10 further includes a detecting component, which can detect the position and state of the whole battery piece 1 on the bearing table 11, and further transmit information to the control system, so that the control system controls the laser device 12 to accurately scribe the whole battery piece 1. Wherein, the detecting member can adopt a CCD (Charge-coupled Device) camera.
In one embodiment, referring to fig. 3 and 4, the whole cell 1 is divided into two parts; at this time, the scribing mechanism 10 can scribe a straight line on the surface of the whole cell piece 1 to divide the whole cell piece 1 into the first part 1' and the second part 1 "; the sheet severing mechanism 20 includes: a first extraction member 21 for extracting the first portion 1'; a second extraction element 22 for extracting a second portion 1 "; and a rotation driving member 23 connected to the first extraction member 21 and/or the second extraction member 22 and capable of driving the first extraction member 21 and the second extraction member 22 to rotate relatively.
Specifically, the first extraction part 21 and the second extraction part 22 are arranged side by side and are rotatably connected through a rotating shaft 24; the rotating shaft 24 is arranged along the extending direction of the dividing line 3; when the first extraction part 21 and the second extraction part 22 extract the first part 1 'and the second part 1', the rotating shaft 24 is opposite to the dividing line 3; the rotary driving member 23 drives the first extraction member 21 and the second extraction member 22 to rotate around the rotating shaft 14, so that the whole battery piece 1 can be broken along the dividing line 3.
The rotary driving member 23 may adopt a linear driving member such as an air cylinder, an electric cylinder, etc.; the output end of the rotary driving piece 23 is rotatably connected with one of the first extraction piece 21 and the second extraction piece 22 through a Y joint, and the other one of the first extraction piece 21 and the second extraction piece 22 is relatively fixedly arranged; when the rotating driving member 23 rotates, one of the first extraction member 21 and the second extraction member 22 rotates towards the other, so that the whole battery piece 1 can be broken. Alternatively, the rotary driving member 23 may adopt two sets of linear driving members, which are respectively connected with the first extracting member 21 and the second extracting member 22 in a rotary manner through Y joints; in this way, during rotation, the rotation driving member 23 can drive the first extraction member 21 and the second extraction member 22 to rotate towards each other, so as to break the whole battery piece 1.
