It is positive can battery, gallium arsenide film solar battery, any one in fuel sensitization solar hull cell.The size of the template
Match with the size of battery layers, template covers all battery layers.
For step 120 as shown in Fig. 2, battery layers are set on substrate, the part that substrate corresponds to the hollow-out parts of template is saturating
Bright, substrate and battery layers form lighttight solar cell substrate；A hollow-out parts, the substrate are at least offered on the substrate
It can be glass substrate, be also possible to solar cell substrate to need transparent region to be transparent substrate, hollow-out part is according to need
It is handled, can be rectangular, diamond shape, circle, heart etc..Substrate can be cut into and battery layers size shape phase as desired
Together.
Step 130 sandblasting removes the part of the battery layers shown from the hollow-out parts of template；To be shown from each hollow-out parts
After the part of existing battery layers is removed, the region that substrate corresponds to each hollow-out parts becomes transparent area；
As shown in Figure 5 and Figure 6, template is removed from battery layers for step 140, is obtained at least one transparent area too
Positive energy cell substrates.
Through the above it is not difficult to find that at least opening up one due to covering template on the surface of battery layers in template and engraving
Empty portion carries out sandblasting to battery layers, to can polish the corresponding battery layers of template hollow-out part by sandblasting, removes dark-coloured electricity
Pond layer, makes this light can be allowed to penetrate by the region that gravel is polished, and the part that substrate corresponds to hollow-out parts is again transparent, by template from electricity
After removing on the layer of pond, the solar cell substrate of light transmission is formed.And the region of template is covered in battery layers, in sandblasting procedures
In, gravel acts in template, so that the battery layers part that template covers it forms protection, so that by the battery of template protection
Layer still exists, therefore after form removal, still can produce electric energy by the battery layer region of template protection, does not influence to make
With.And then by solar cell substrate and the solar components use formed by it when in building, light may pass through solar energy
Cell substrates and solar components enter in building, make building interior bright, are not necessarily to other floor lights during the day, save money
Source, but also the usage experience sense of building is more preferable.

Row blasting treatment.Specifically, pipeline conveys opaque solar cell substrate and moves in sandblasting area, meanwhile, sandblasting is set
Standby spray head is also moved along the moving direction perpendicular to battery layers, is sprayed on gravel to battery layers, in solar cell substrate
Battery layers are polished not covered with the battery layers of template, and allow the corresponding template hollowed out area light-permeable of battery layers, are formed saturating
Light area obtains solar cell substrate as shown in Figure 4 and Figure 5.To which the battery layers of corresponding region on template vacancy section be beaten
Mill is clean, makes to be polished clean region light-permeable.
Further, the linear velocity that pipeline drives battery layers to pass through sandblasting area is 0.6m/min~1.2m/min；
The blasting pressure of abrasive blast equipment is 0.1Mpa~0.3Mpa.To may make in battery layers not by template overlay area
Battery layers be polished completely completely.
Further, sandblasting removes from the part steps of the battery layers shown in the hollow-out parts of template, can also pass through
Following steps carry out sandblasting:
The battery that step 131 will be covered with template is placed in the sandblasting area of abrasive blast equipment；Specifically, battery layers are put into
Into sandblasting area, battery layers are first placed on substrate, therefore are placed into sandblasting area together with substrate.
Step 132 is after battery layers stand preset duration in the sandblasting area of abrasive blast equipment, from the sandblasting area of abrasive blast equipment
Middle to take out the battery layers for being covered with template, abrasive blast equipment is used for the process stood in sandblasting area in the battery layers for being covered with template
In, blasting treatment is carried out to battery layers.Specifically, abrasive blast equipment is to the comprehensive sandblasting of battery layers in sand blasted area, gravel
The region for not having template to cover in battery layers is touched, the battery layers in the region are polished clean, light-permeable.
It further, further include following steps after the step of template being removed from battery layers；
Step 160 cleaning solar energy cell substrate, obtains clean solar cell substrate；
Solar cell substrate after step 170 drying cleaning.Specifically, the solar cell substrate cleaned is put
Moisture is evaporated to drying area, or is directly dried good.
Further, cleaning solar energy cell substrate specifically comprises the following steps；
Solar cell substrate is totally submerged in the cleaning solution being provided previously or cleaning solution is sprayed at solar-electricity
On the substrate of pond, clean solar cell substrate is obtained.
Specifically, solar cell substrate is totally submerged in the cleaning solution being provided previously, is specifically included:
The service sink for being placed with cleaning solution is provided previously, cleaning solution can be water；
Solar cell substrate is completely soaked in service sink；
After immersion for a period of time, solar cell substrate is taken out from service sink, obtains clean solar battery
Substrate.
In addition, cleaning solution is sprayed on solar cell substrate, specific steps are as follows:
Solar cell substrate after sandblasting is placed into the cleaning area of sprayable cleaning solution；Specifically, biography can be passed through
Send band that solar cell substrate is transported to cleaning area.
To the solar cell substrate jet cleaning liquid after sandblasting, remaining gravel is rinsed.Specifically, by solar-electricity
After pond substrate is put into cleaning area, cleaning sprayer is opened, cleaning sprayer sets solar cell substrate jet cleaning liquid, cleaning sprayer
Have multiple, comprehensive can be ejected into solar cell substrate, the gravel dust etc. on solar cell substrate is cleaned up.?
After a certain period of time, solar cell substrate is taken away cleaning area again by transmission belt for cleaning.
Second embodiment of the present invention is related to a kind of preparation method of solar components.In second embodiment of the invention
In, as shown in figure 11, include the following steps:
Step 180 as shown in figure 9, be sequentially placed the cover board 7 of at least partly light transmission, glue film 6, above-mentioned embodiment party from top to bottom
Solar cell substrate made from the preparation method of the solar cell substrate of light transmission made from formula；Specifically, glue film 6 is covered
The surface of battery layers 2 is covered, then glass cover-plate 7 is covered on glue film 6；Glue film 6 is polyvinyl butyral PVB glue film, second
Any one in alkene-vinyl acetate copolymer eva glue film and polyolefin elastomer glue film or composition, cover board 7 can be glass
Glass cover board.
Step 190 carries out lamination to cover board 7, glue film 6, solar cell substrate or rolling is handled, and obtains doubling component；Tool
Body is said, is integrally applied pressure and heating to glass cover-plate 7, glue film 6, solar cell substrate by method laminated into type, is made
6 part of glue film fusing, paste glass cover-plate 7 and solar cell substrate, allow glass cover-plate 7 and solar battery substantially not
It can move.
Doubling component is put into autoclave and heats by step 200, obtains solar components.The solar components are as schemed
Shown in 8, includes substrate, battery layers 2, glue film 6 and cover board 7, there is transparent area 5 in battery layers 2.Specifically, it pre-fixes
In autoclave, glass cover-plate 7 and solar cell substrate are sticked together doubling component by all fusings of glue film 6 completely,
It is taken out after being heated to preset time, takes out the cover board 7 and solar cell substrate being sticked together by glue film 6.
Optionally, the temperature in autoclave is 125 DEG C~140 DEG C.So that the fusible adhesion glass cover-plate 7 of glue film 6
With thin film solar transparent substrate.
