    • The present invention provides module structures and methods of manufacturing rigid or flexible photovoltaic modules employing thin film solar cells fabricated on flexible substrates, preferably on flexible metallic foil substrates. The solar cells may be Group IBIIIAVIA compound solar cells or amorphous silicon solar cells fabricated on thin stainless steel or aluminum alloy foils. In one embodiment, initially a solar cell string including two or more solar cells is formed by interconnecting the solar cells with conductive leads or ribbons. At least one bypass diode electrically connects conductive back surfaces of at least two solar cells. The bypass diode and the solar cells are encapsulated with support material and are packed with the protective shell such that the at least one bypass diode is placed between at least one solar cell and the bottom protective sheet. The bypass diode is thermally connected to the back conductive surface of one of the solar cells so that the back conductive surface of the solar cell functions as a heat sink.
    • 本发明提供了制造刚性或柔性光伏组件的模块结构和方法,所述光伏模块采用在柔性基板上制造的薄膜太阳能电池,优选地在柔性金属箔基板上。 太阳能电池可以是在薄的不锈钢或铝合金箔上制造的IBIIIAVIA族复合太阳能电池或非晶硅太阳能电池。 在一个实施例中,最初通过将太阳能电池与导电引线或带相互连接来形成包括两个或多个太阳能电池的太阳能电池串。 至少一个旁路二极管电连接至少两个太阳能电池的导电后表面。 旁路二极管和太阳能电池被支撑材料封装并且被封装有保护壳,使得至少一个旁路二极管被放置在至少一个太阳能电池和底部保护片之间。 旁路二极管热连接到太阳能电池之一的背面导电表面,使得太阳能电池的背面导电表面起散热作用。

    • Described is a continuous electroless deposition method and a system to form a solar cell buffer layer with a varying composition through its thickness are provided. The composition of the buffer layer is varied by varying the composition of a chemical bath deposition solution applied onto an absorber surface on which the buffer layer with varying composition is formed. In one example, the buffer layer with varying composition includes a first section containing CdS, a second section containing CdZnS formed on top of the already deposited CdS, and a third section containing ZnS is formed on the second section All the process steps are applied in a roll-to-roll fashion. In another example, a transparent conductive layer including a first transparent conductive film such as aluminum doped zinc oxide and a second transparent conductive film such as indium tin oxide is deposited over the buffer layer with the varying composition.
