The round ingot is then cut into so-called wafers, which are cut to the required size of the PV cell. Of course, such a purity of the material cannot be achieved with this technology, the transitions between the crystals are visible in it.\u003cbr\/\u003e\u003cbr\/\u003eAdvantages of polycrystal:\u003cbr\/\u003eSlightly higher yield of scattered light production (unfavorable light conditions)\u003cbr\/\u003e\u003cbr\/\u003e\u003cbr\/\u003eTechnical parameters:\u003cbr\/\u003e\u003cbr\/\u003e- Dimensions: 670 x 410 x 25mm\u003cbr\/\u003e- Dural frame 25mm, cover glass.\u003cbr\/\u003e- Max no-load voltage Voc = 21.6V\u003cbr\/\u003e- Max.
