It is very difficult to manufacture a tandem solar cell with 4–5 junctions. More importantly, multi-junction solar cells cannot be achieved without careful consideration of the lattice constants of the materials.

Advances in upconversion enhanced solar cell performance
The c-Si solar cells have the smallest band gap which allows them to absorb up to 1100 nm of the solar radiation, but even these cells incur more than 19% loss in efficiency due to this incapability to fully utilize the IR part of the solar spectrum. For other types of solar cells, these losses are even higher, amounting up to 50% [10].

When absorbing layer thickness exceeds the diffusion length, the charge carriers generated in the solar cell device start to recombine, and the series resistance of the cell will also increase. So, a smaller number of generated carriers will reach the electrode. Thus, solar cells are incapable of achieving high efficiency.

6 FAQs about [Solar cells cannot be installed if the number of layers exceeds]
How many solar panels can I install?
While there is no maximum number of panels you are allowed to install, installations above 3.68kW (typically 8 - 11 panels) require prior approval. There is no legal limit to the amount of solar energy you can generate. However, earnings through the Smart Export Guarantee do not apply to solar systems larger than 5MW.
How many solar panels can you have in the UK?
What’s the maximum number of solar panels you can have in the UK? Assuming your property doesn’t require planning permission for a solar installation, there is no legal maximum number of solar panels that you can install on your roof in the UK. Other than usable roof space, there is nothing limiting how many solar panels you can put up there.
Is there a maximum number of solar panels you can have?
There is no maximum number of solar panels you can have. Of course, at some point you’ll run out of space – after all, there are only so many panels you can physically fit on your roof or land, even if you own dozens of acres.
How many solar installations are allowed?
only one standalone solar installation is permitted. Regulations introduced in April 2015 deem most non-domestic solar installations below 1 MW as permitted development, provided: a ground mounted array is no more than 9m2, no more than 3m in any one direction and no higher than 4m.
Should you install a larger solar panel system?
When you install a larger solar panel system, you can split the fixed costs among more panels, which ends up reducing the cost per panel. Installing solar panels offers many benefits, and it makes financial sense to get as many panels as possible once your scaffolding is set up.
Do you need planning permission for solar panels?
Listed buildings and properties in conservation areas usually require planning permission for solar panels, but for the majority of other homes a solar installation counts as a ‘permitted development’. However, it is a legal requirement of all rooftop solar panel installations that no panel sits closer than 400mm from the edge of the roof.
