This article discusses the role of semiconductors in solar cells/photovoltaic (PV) cells, specifically their function and the types used. Image Credit: Thongsuk7824/Shutterstock.com

Are semiconductors used in solar energy conversion based on photovoltaics?

Nature Communications 12, Article number: 4622 (2021) Cite this article Semiconductors have been used in solar energy conversion for decades based on the photovoltaic effect. An important challenge of photovoltaics is the undesired heat generated within the device.

What are compound semiconductor-based solar cells?

Compound semiconductor-based PV cells have two aspects: group III-V semiconductor-based solar cells and chalcogenide-based solar cells. Group III-V semiconductor-based solar cells use semiconductors made of elements from groups III (gallium, aluminum) and V (arsenic, phosphorus) of the periodic table.

How do semiconductors convert solar energy into heat?

Semiconducting materials convert solar energy into heat by absorbing the photon energy larger than their bandgaps, so that electrons in the valence band (VB) are able to be excited to the conductive band (CB). Next, excitation-state electrons and holes are produced in the CB and VB, respectively.

Are silicon semiconductors a good choice for solar cells?

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.

How do semiconductors work in PV cells?

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.
