Scalable ways to break the efficiency limit of single-junction solar cells
The detailed-balance single-junction efficiency limit assumes that the solar cell consists of a single absorber layer, in which an incoming photon generates a single electron–hole pair that can be extracted to perform work. 5 All common schemes that go beyond this limit break at least one of these assumptions: they use two or more absorber layers with different optical

Scalable ways to break the efficiency limit of single-junction solar cells
A tandem solar cell consists of two individual sub-cells, each having its own bandgap and its own junction to aid electron-hole separation. An important commercial consideration is that perovskite/Si tandem modules offer a higher efficiency than traditional Si-only modules, which allows the producer to charge a premium in applications where space is limited such as in

Walking on solar panels? Will it break them? : r/solar
Walking on those areas won''t cause the glass to crack. However, unless your foot is size 0.5, you''re still exerting force on the cells. The thought is that you''ll cause microfractures to the cells which will lead to premature cell failure. The only way to tell you have these cracked cells is to do EL testing which would be a nightmare on a roof.
