PHOTOVOLTAIC MODULE
FIG2 is a cross section of a second embodiment of a solar deflector according to the invention  FIG5 is a cross section of a fifth embodiment of a solar deflector according to the invention  FIG4 is a cross section of a fourth embodiment of a solar deflector according to the invention
In the second embodiment of the deflector 100 according to the invention, illustrated in FIG2, on the other hand, the reflective surfaces 101 are oriented in opposite directions relative to each other, but not there is not the sequence 102 of reflective surfaces 103 which, on the other hand, is present in the first embodiment. Consequently, each of the two reflective surfaces 101 has a relative first end joined at an angular point with the first end of the reflective surface 101 opposite to it, and a second end which joins with a planar bottom wall 104 forming, the latter, a rear face of the solar deflector module. The embodiment of the collector illustrated in FIG2 may also be made in such a way that the deflector 100 is formed by transparent material, since in this way the solar radiation may enter in the deflector 100 starting from the bottom wall 104 and then reflect on the reflective elements 101 and/or 103 from the side inside the deflector 100. Moreover, it is necessary to emphasise that the use of transparent material also allows the use of the deflector 100 in the embodiment shown in FIG2 in a two-face module.  Lastly, the fifth embodiment of the collector according to the invention is shown in FIG5. In this configuration, the sequence 102 of reflective surfaces 103 is joined with a planar bottom wall 104 substantially lying in contact with the angular points formed by the joints of the reflective surfaces. The embodiment of the collector illustrated in FIG5 may also be made in an overturned manner, that is to say, with the bottom wall 104 glued or welded in the groove of the covering layer 202. In this case, it is necessary that the deflector 100 is formed by transparent material, since in this way the solar radiation may enter in the deflector 100 starting from the bottom wall 104 and then reflect on the reflective elements 101 and/or 103 from the side inside the deflector 100. Moreover, it is necessary to emphasise that the use of transparent material also allows the use of the deflector 100 in the embodiment shown in FIG5 in a two-face module.  A fourth embodiment of the deflector 100 according to the invention is illustrated in FIG4. The fourth embodiment is similar to the third embodiment described above. The fourth embodiment also has reflective surfaces 101 which are oriented in the opposite directions to each other, and each has a first end joined with the first end of the other reflective surface 101 so as to form an angle at the top which is convex and a second end which is joined with a first end of respective connecting surfaces 105, oriented in an oblique direction relative to the two main reflective surfaces 101, so as to form acute inner angles. The second end of the connecting surfaces 105 has reached the sequence 102 of reflective surfaces 103 lying at a lower height and which corresponds in use to the rear face of the photovoltaic module.
