Up to 1990 the solar cells were created on the base of single crystal, poly-crystal and amorphous Si. Multi-junction (MJ) solar cells are solar cells with multiple p–n junctions made of different semiconductor materials.Each material's p-n junction will produce electric current in response to different wavelengths of light.The use of multiple semiconducting materials allows the absorbance of a broader range of wavelengths, improving the cell's sunlight to electrical energy conversion efficiency. In addition, heterojunctions can be formed and multijunction solar cells can be produced to convert more of the solar spectrum into electricity and thus exceed the theoretical limits set by the Shockley–Queisser limit. The main challenge in this approach is a conductive direct wafer bond Dual-junction GaAs solar cells were grown on a p +-GaAs substrate. Triple Junction cells have been proven to be easier to grow than higher multi junction cells and are more efficient than single junction cells [1]. Process improvements and a very large boost in production have brought that figure down 99%, to 68¢ per watt in 2016, according to data from Bloomberg New Energy Finance.
