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 III–V semiconductor materials provide a relatively convenient system for fabricating multi-junction solar cells providing semiconductor materials that effectively span the solar spectrum as demonstrated by world record efficiencies (39.2% under one-sun and 47.1% under concentration) for six-junction solar cells.
This solar cell used gallium arsenide (GaAs) and aluminum gallium arsenide (AlGaAs) materials which consisted of an AlGaAs-GaAs tandem cell structure utilizing a very thick (due to The liquid phase epitaxy (LPE) growth method) AlGaAs/AlGaAs tunnel junction. A further evaluation of this tunnel junction was later published .
From one of the future consideration applications, there also exist three-junction solar cells on metal or silicon substrates. For terrestrial uses, the concentration process of multiple-junction cells is important. The CPV systems have also ability to reduce the cost.
