A multi junction solar cell (MJSC) has already been demonstrated as the answer. A MJSC uses multiple p-n semiconductor junctions connected in series to absorb different wavelength ranges of the solar spectrum enabling light conversion efficiencies which surpasses the theoretical S-Q limit (Nikoletatos and Halambalakis, 2018).
Single junction solar cells are limited by the S-Q limit at a maximum efficiency of approximately 33%. MJSCs are proven to be the champion among all the solar cell technologies both in laboratory and module scale with the use of multiple semiconductor absorbers to attain record efficiencies.
Multi-junction solar cells are sometimes called tandem cells, usually when they consist of two materials with very different band gaps. One of the disadvantages and limits of multi-junction solar cells is that the carriers have to diffuse out to the metal contacts, which limits having a huge stack of junctions.
Because state-of-the-art efficiencies of single-junction solar cells are approaching the Shockley-Queisser limit, the multi-junction (MJ) solar cells are very attractive for high-efficiency solar cells. This paper reviews progress in III–V compound single-junction and MJ solar cells.
The number of junctions so far has included two-junction, triple-junction, four-junction, five-junction and six-junction solar cells. Multi-junction solar cells are sometimes called tandem cells, usually when they consist of two materials with very different band gaps.
The drawbacks can be that a single junction solar cell can't absorb the full spectrum of the incident light, hence, affects the efficiency of the cell. This could be overcome by using a multi-junction solar cell. The performance can further be improved by implementing MPPT. The MPPT can be executed with the help of different algorithms.

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 multi-junction solar cell tries to rectify this inefficiency by presenting multiple band gaps to the incoming sunlight. Basically, it presents a series of materials and junctions to the light, usually starting with the highest energy (shortest wavelength) light at the top of a stack, and working down to the lowest energy (longest wavelength ...
