摘要： An electrically conductive substrate is provided with a predetermined electrical pattern. A solder paste is deposited onto the electrically conductive substrate at pre-defined interconnection locations. A first encapsulant layer provided with a pattern of openings is placed onto the electrically conductive substrate. Back-contact solar cells are placed on the first encapsulant layer so as to have a match of the electrical pattern of the back-contact solar cells with the electrical pattern of the electrically conductive substrate. A second encapsulant layer is placed on the back-contact solar cells with a glass layer placed on the second encapsulant layer. Heat and pressure are applied to the components to cause the encapsulant materials to flow and form a monolithic photovoltaic module. A laser is applied to the solar cell from the side of the glass layer to cause the solder paste to reflow between each interconnection location and its matching connection location on the back-contact solar cell.

摘要翻译： 导电基板设置有预定的电气图案。 在预定义的互连位置处，将焊膏沉积到导电基板上。 具有开口图案的第一密封剂层被放置在导电基底上。 背接触太阳能电池被放置在第一密封剂层上，以便使背接触太阳能电池的电气图案与导电基板的电气图案相匹配。 第二密封剂层被放置在背接触太阳能电池上，玻璃层放置在第二密封剂层上。 将热和压力施加到部件上以使密封剂材料流动并形成单片光伏模块。 从玻璃层的侧面向太阳能电池施加激光，使得焊锡膏在每个互连位置与背接触太阳能电池上的匹配连接位置之间回流。
