Flexible thin film solar cell of high power density gaAs multijunction relates to gaAs multijunction flexible solar cell array production technical field. The utility model discloses set up the battery epitaxial layer on one side of the bottom electrode, set up electrode and antireflection coating on the battery epitaxial layer, the battery epitaxial layer includes battery and P type inGaAs contact layer at the bottom of battery among N type gaAs contact layer, gaInP top battery, first tunnelling knot, the gaAs, second tunnelling knot, the inGaAs. The utility model discloses the product is upper and lower electrode only, adds epitaxial layer and antireflection coating to the linerless end is supported, has the characteristics of higher gravimetric specific power and ultra -thin nature, and product thickness is only on about 10~15 mu m, and output does not influence each other, the autonomous working. In addition, have crooked characteristic, but greatly increased solar battery's range of application. 高比功率GaAs
