New animation: From ingot to cell

We published the educational exploded-view animation "From ingot to cell", showing how a photovoltaic cell is made.

The animation follows four stages:

1. Ingot - very pure silicon is melted and a single large crystal is slowly pulled from the melt.
2. Wafer - the ingot is shaped into a block and wire-sawn into slices a fraction of a millimetre thick.
3. Texture - the wafer surface gets microscopic pyramids that help capture light.
4. Cell - thin layers are added to the wafer: anti-reflective coating, passivation layers and front and rear metal contacts.

The result is the component that turns sunlight into electricity. SOLYWATT ROMANIA plans to make this step in Romania, through its planned TOPCon+ photovoltaic cell factory in Galati, with a capacity of 1.17 GW.
