The utility model provides a flexible thin film solar cell of germanium base gaAs multijunction, relates to thin film solar cell's production technical field. Pass through the bonded layer in one side of flexible substrate and connect the ge stratum basale, set up the bottom electrode on some ge stratum basales, set up the epitaxial layer on another part ge stratum basale, set up electrode and antireflection film layer on the epitaxial layer. Knot high -efficient flexible solar cell array in germanium quito has reached bendability, comparatively light and handy purpose, is favorable to improving solar battery operating range and gravimetric specific power, and simultaneously, upper and lower electrode adopts the mode of homonymy design to make things convenient for the use, can the beading on the device that uses, perhaps the adhesion use on not only softness but also slim and graceful transparent PI. 种锗基砷化镓多结柔性薄膜太阳电池，涉及薄膜太阳电池的生产技术领域。在柔性衬底的侧通过键合层连接Ge基底层，在部分Ge基底层上设置下电极，在另部分Ge基底层上设置外延层，在外延层上设置上电极和减反射膜层。锗基多结高效柔性
