Abstract
This invention relates to a method for producing solar cells, and photovoltaic panels thereof. The method for producing solar panels comprises employing a number of semiconductor wafers and/or semiconductor sheets of films prefabricated to prepare them for back side metallization, which are placed and attached adjacent to each other and with their front side facing downwards onto the back side of the front glass, before subsequent processing that includes depositing at least one metal layer covering the entire front glass including the back side of the attached wafers/sheets of films. The metallic layer is then patterned/divided into electrically isolated contacts for each solar cell and into interconnections between adjacent solar cells.
