High efficiency quadruple junction solar cells
There have been theoretical studies on using quadruple junction solar cell with 1 eV InGaAsN as the third subcell on Ge for effective usage of the solar spectrum [9]. However, for the InGaAsN layer, poor minority carrier lifetime in the base region has been identified as one of the key limiting factors for further efficiency improvement [10,11].

Multi-junction solar cells paving the way for super high-efficiency
The breakdown between power generated by the solar cell and these losses is illustrated in Fig. 2. 6 For a single-junction solar cell, the two largest losses are the thermalization and below-Eg losses, both of which are significantly mitigated with the addition of semiconductor junctions with different bandgap energies in an MJ device.
