Photovoltaic module comprising a terminal box attached to the rear surface
US 7952016 B2
said rear surface member is a light-transmitting member, and said photovoltaic submodule is a double-sided light receiving type photovoltaic submodule.
It is therefore an object of the present invention to provide a photovoltaic module capable of preventing insulation failure between the outer frame and connection leads without a unique-shaped terminal box.
FIG. 1 is a plan view illustrating a photovoltaic module according to the first embodiment of the present invention.
Embodiments of the present invention will be described in detail with reference to the drawings. The same reference numbers are given to components that are identical with or equivalent to each other and their descriptions will be omitted to avoid repetition.
As shown in FIG. 4, the solar cell 11 comprises an n-type single crystalline silicon (c-Si) substrate 110 with a (100) plane (hereinafter referred to as n-type single crystalline silicon substrate 110) having resistivity of about 1 Ω·cm and a thickness of about 300 μm, as a crystalline semiconductor substrate. There are pyramidal projections and depressions (not shown) having a height of a few micro meters to several tens of micro meters on a surface of the n-type single crystalline silicon substrate 110. The projections and depressions are made for confining light. As a substantially intrinsic amorphous semiconductor thin film layer including hydrogen, a substantially intrinsic (i-type) amorphous silicon (a-Si:H) layer 112 having a thickness of 3 nm to 250 nm is formed on the n-type single crystalline silicon substrate 110 by an RF plasma CVD method. In addition, a p-type amorphous silicon layer 113 having a thickness of about 5 nm is formed on the i-type amorphous silicon layer 112, as a doped amorphous semiconductor thin film layer including hydrogen.
In this embodiment, five terminal blocks are provided for four connection leads. No connection lead is connected to the terminal block 33 e in this embodiment. Therefore, the terminal block 33 e and the terminal block 33 c are connected through a jumper wire. A bypass diode 34 is connected between the terminal blocks 33 a and 33 b, the terminal blocks 33 b and 33 e, and the terminal blocks 33 c and 33 d.
The connection between the terminal box 30 and the connection leads 15 a, 15 b, 15 c and 15 d are made as follows: the connection leads 15 a, 15 b, 15 c and 15 d individually pass through the insertion holes 36; and the connection leads 15 a, 15 b, 15 c and 15 d are soldered to the terminal blocks 33 a, 33 b, 33 c and 33 d, respectively. A cable 17 inserted through an insertion hole 37 is fixed firmly to the terminal block 33 a by crimping for example. Similarly, the other cable 17 inserted through the other insertion hole 37 is fixed firmly to the terminal block 33 d by crimping for example. If necessary, a bushing may be attached to the insertion hole 37 to enhance waterproofness. Additionally, though not shown, a member to prevent the cable from slipping off may be provided to the terminal box 30 to enhance mechanical strength.
In this embodiment, the connection leads 15 are routed from between the upright part 38 and the outmost edge of the rear surface side light-transmitting substrate 13 to be inserted into the terminal box 30. This structure makes it easier to handle the connection leads 15. In addition, there is no conventional problem of disconnection and insulation failures of the connection leads 15 because the connection leads 15 are not drawn into the fitting part 22 a.
As discussed above, the connection leads 15 can be routed into the terminal box 30 though the gap between the upright part 38 of the terminal box 30 and the edge of the photovoltaic submodule 10. Consequently, the connection leads 15 are blocked by the upright part 38 of the resin terminal box 30 so as not to directly abut the outer frame 20, thereby fully ensuring insulation properties of the connection leads 15 even having a thin insulating coat.
