Abstract

The invention provides a method for manufacturing a photovoltaic cell panel. The method comprises the following steps of: coating a UV cured material on a photovoltaic cell plate and a substrate; assembling the photovoltaic cell plate and the substrate coated with the UV cured material into a photovoltaic cell assembly; performing vacuum treatment on the photovoltaic cell assembly; and curing the UV cured material in the photovoltaic cell assembly to obtain the photovoltaic cell panel. Compared with the photovoltaic cell panel in the prior art, the photovoltaic cell panel of the invention uses the UV cured material as an adhesive to replace a traditional EVA hot melt adhesive; and therefore, the photovoltaic cell assembly can be assembled into any curved surface shape and the photovoltaic cell assembly can be obtained by curing the photovoltaic cell plate through UV. In addition, the photovoltaic cell assembly is molded by vacuum negative pressure rather than lamination, so that pressure applied to the photovoltaic cell plate is uniform, and cracks of the cell plate are not easy to cause.
