As shown in FIG. 2, a transparent electrode 21 and an amorphous silicon layer 2 are provided on the main surface of a transparent glass substrate 20.
2. A plurality of amorphous silicon photovoltaic devices (cells) each having back electrodes 23 laminated in this order are sequentially connected to the transparent electrodes 21 and back electrodes 23 of each adjacent photovoltaic device, and the entire structure is assembled. are connected in series to form an amorphous silicon solar cell module (integrated 9-stage cell: 10 cm square), and current is applied in the forward direction, that is, from the anode side to the cathode side.
When 0.5 A (55 mA/cm 2 ) was passed through the photovoltaic element, the surface of the photovoltaic element could be heated to form a difference of about 20° C. from the outside temperature.

could be heated to form a difference between Furthermore, when the amorphous silicon solar cell described above was installed on the ground and a current of 0.5 A was passed through it in the forward direction, 10 cm of snow fell around it, but no snow fell on the solar cell at all.
なお上記の説明はアモルフアスシリコン太陽電

いてもよいことは勿論である。 Although the above description is an example of an amorphous silicon solar cell, it goes without saying that a single crystal Si solar cell may also be used.

熱効果が得られることが明らかである。 The solid line in the graph shows the characteristics of single-crystal silicon solar cells, and the broken line shows the characteristics of amorphous silicon solar cells. As is clear from this graph, for example, when a current of 0.1 A/cm 2 is passed, the voltage is 0.6 V for a single crystal silicon solar cell, and 1.2 V for an amorphous silicon solar cell. The amount of heat generated by amorphous silicon solar cells is twice that of single-crystalline silicon solar cells, and it can be seen that amorphous silicon solar cells can generate heat more efficiently, but in either case, the heat generation effect is sufficient. It is clear that this can be achieved.

As described above, since the device of the present invention is equipped with means for passing current through the photovoltaic element in its forward direction, the photovoltaic element can be caused to generate heat at any time by passing this current. This makes it possible to use solar cells even in winter, especially in snowy areas where there is a risk that solar cells may be cut off due to snowfall, improving efficiency, and eliminating the need for labor for snow removal, resulting in significant savings. The present invention has excellent effects such as labor saving.
