The central semiconductor parameters that determine the design and performance of a solar cell are: i) concentrations of doping atoms, which can be of two different types; donor atoms which donate free electrons, ND, or acceptor atoms, which accept electrons, NA. The concentrations determine the width of a space-charge region of a junction.
Semiconductors in PV cells absorb the light’s energy when they are exposed to it and transfer the energy to electrons. The absorbed additional energy allows electrons to flow in form of an electrical current through the semiconductor material.
To summarize, silicon semiconductors are currently playing a critical role in the large-scale manufacturing of solar cells with good efficiency and durability. In the future, all-perovskite tandems are expected to become more prevalent as they are cheaper to produce compared to silicon cells.
