Abstract: The solar cell structure is an important factor for realization of better efficiency of a solar cell in conversion of optical source in to electrical source. Using more efficient solar cell, the production cost of solar power can be minimized. Multi-junction Tandem Solar Cells are most effective in conversion of solar energy in to electrical energy. One triple junction III-V tandem solar cell is fabricated in virtual wafer fabrication lab (VWF) in this paper. Three numbers of multi-junction solar cells are designed and fabricated with the III-V materials and stacked on each other with the sequence of descending order of band gap energy and these three cells are inter connected with two tunnel diode. The mesh structure of this fabrication is done in auto-mesh mode which creates cylinders in mesh. The efficiency of this Triple Junction (T-J) solar cell is achieved 30.671% and the Fill Factor of this cell is derived 77%.
