The working of solar cells involves light photons creating electron-hole pairs at the p-n junction, generating a voltage capable of driving a current across a connected load.
For single-junction perovskite solar cells (PSCs), the performance of bifacial configurations is still far behind that of their state-of-the-art monofacial counterparts. Here, we report on highly efficient, bifacial, single-junction PSCs based on the p-i-n (or inverted) architecture.
A solar cell functions similarly to a junction diode but has a different construction. Instead of a typical p-n junction, a solar cell has a very thin layer of p-type semiconductor grown on a relatively thicker n-type semiconductor. Then, a few finer electrodes are applied on the top of the p-type semiconductor layer.
