Potential of polysilicon solar cells 3.1. Confinement of light Silicon is a material with an indirect band gap which absorbs light up to a few microns thin layer. In solar cells, the material should be a good absorber so that the imposing light is confined to achieve high absorbance .
The present article gives a summary of recent technological and scientific developments in the field of polycrystalline silicon (poly-Si) thin-film solar cells on foreign substrates. Cost-effective fabrication methods and cheap substrate materials make poly-Si thin-film solar cells promising candidates for photovoltaics.
Here is a primer. Polysilicon, a high-purity form of silicon, is a key raw material in the solar photovoltaic (PV) supply chain. To produce solar modules, polysilicon is melted at high temperatures to form ingots, which are then sliced into wafers and processed into solar cells and solar modules.

In the as-crystallized state, the quality of such SPC poly-Si material is not sufficient for photovoltaic applications as it contains many deep level intra-grain defects and grain-boundary defects, limiting the electrical performance.
With 10.4%, the current poly-Si thin-film solar cell efficiency record is held by a device fabricated by solid phase crystallization. However, due to a limited material quality in terms of open circuit voltage and due to time-consuming, expensive fabrication techniques the commercial success was limited so far.
Fabricated as thin layers, polycrystalline silicon also features all advantages of thin-film technologies, namely low costs due to low material wastage with up to factor 100 less material compared to wafer-based solar cells, and the technically feasible monolithic fabrication of large area devices.
