Depicted in another possible embodiment Fig. 8.The process sequence of script, it is to be initially formed photoelectric conversion layer 203, then sequentially forms second
Shallow trench isolation I2, the second conductive layer 204, the first shallow trench isolation I1.Due to the first shallow trench isolation I1 and the second shallow trench isolation I2 mono-
As all be cut by laser formed, and formed all pass through film-plating process as the conductive layer 204 of photoelectric conversion layer 203 and second.For
Avoid being cut by laser processing procedure and film-plating process staggeredly performs the not convenient property brought, then swashed again after can first completing film-plating process
Light cuts processing procedure.For example, the conductive layer 204 of photoelectric conversion layer 203 and second is first sequentially formed with film-plating process, then swashed
Light cutting processing procedure is initially formed the first shallow trench isolation I1, then forms the second shallow trench isolation I2 ', or be initially formed the second shallow trench isolation
I2 ', re-form the first shallow trench isolation I1.Now, because the first shallow trench isolation I1 and the second shallow trench isolation I2 ' are all to cut through photoelectricity to turn
The conductive layer 204 of layer 203 and second is changed, therefore the second shallow trench isolation I2 ' is not like the second shallow trench isolation I2 tools in previous embodiment
Have to form the effect of export positive contact, therefore conductive materials 205 are inserted in the second shallow trench isolation I2 ' using wire mark or other modes
To form positive contact.

301 is incident.One application examples of foregoing solar cell hollow out circuit 200, it is to be formed with reference to a display panel 301 such as Fig. 9 institutes
The solar cell display device 300 illustrated.It is by taking handheld electronic book as an example in Fig. 9, display panel 301 is covered into substrate
The opening O of center is in order to opposed open O position displays word or pattern on 201.Now, under e-book frame portion
Side, that is, correspond to the hollow circle zone A of solar cell hollow out circuit 200.Through solar cell hollow out circuit 200, you can
Electric energy is stored in the lump when the reading electronic book of one side, to provide electric power needed for display panel 301.The solar cell of the present invention
In hollow out circuit 200, due to the particular arrangement mode of structure, make path of the carrier in the first conductive layer 202 shorter, thus make
Fill factor, curve factor (Fill Factor) is improved and improves electric extraction efficiency.Whereby, hollow circle zone A areas are only the O that is open
The 1/8 of area can provide enough electric power, and the present invention can significantly concede configuration space to display panel 301, and then greatly improve
The viewing area of e-book.Furthermore due to the particular arrangement mode of the first conductive layer 202 and the second conductive layer 204, make the present invention
Solar cell display device 300 have concurrently using upper diversity, such as be easy to integrate with external device (ED) and be unlikely to increase
Volume is significantly increased in complicated processing procedure.
In the present invention, the first conductive layer 202 and 204 visual actual state of the second conductive layer and change the configuration of its both positive and negative polarity.
In Figure 10 A, the selection of the first conductive layer 202 is positive electrode material, and the selection of the second conductive layer 204 is negative electrode material, therefore is leaned on
Nearly opening O the first circle zone A1 is that the second circle zone A2 as a negative contacts, and away from opening O is relative conduct
One positive contact.Now, light L can expose to photoelectric conversion layer 203 by substrate 201, convert light energy into electric energy, and in generation
Current loop S.
In another possible embodiment, as depicted in Figure 10 B.The selection of first conductive layer 202 is negative electrode material, and the
The selection of two conductive layers 204 be positive electrode material, thus close opening O the first circle zone A1 be as a positive contact, it is and remote
The the second circle zone A2 for leaving mouthful O is to be used as a negative contacts relatively.Now, light L can expose to light by display panel 301
Electric conversion layer 203, convert light energy into electric energy, and current loop S in generation.
Aforementioned positive electrode contact, negative contacts and light L incident directions can freely arrange in pairs or groups to obtain more broad application
Scope.
To sum up, solar cell hollow out circuit 200 provided by the invention can integrate in a simple manner with display panel 301 and
Form solar cell display device 300.Such a solar cell display device 300 can have larger effective area, and
Based on the configuration mode of special positive and negative electrode contact, can have and apply upper elasticity.
Although the present invention is disclosed above with embodiment, so it is not limited to the present invention, therefore the guarantor of the present invention
Shield scope is worked as to be defined depending on the scope of which is defined in the appended claims.
