The Construction and Working Principles of Photovoltaic Cells

The process of making a photovoltaic cell is a series of steps. These steps make sure the cell can turn sunlight into electricity well. To begin, polysilicon is made from a mix of reactive gases. This includes silicon, hydrogen, and chlorine. This mix creates the base material for capturing solar energy. For a type of silicon called monocrystalline, a special process

6 FAQs about [Video of the principle of photovoltaic cell texturing process]

What is the purpose of texturing a solar cell?

Texturing is used to reduce the reflection of light from the front surface and to improve light trapping in a solar cell. The first objective of texturing is to minimise the front-surface reflectance so that more photons remain, which can be absorbed by the solar cell resulting in a larger short-circuit current density, Jsc.

Does a single emitter photovoltaic (PV) surface texture affect doping uniformity?

Results show that the initial texturing topology and reflectivity is not affected by the subsequent rinses and the doping uniformity is also the same as with the standard chemicals. Texturing of the surface is the first step of the single emitter photovoltaic (PV) manufacturing process for both mono- and multi-crystalline silicon wafers.

What is alkaline texturing?

How does the texturing process work?

The texturing process roughens the surface and reduces the reflection of the silicon surface by etching along crystal planes and grain boundaries to increase the surface area to provide more light trapping.

How does alkaline texturing a silicon wafer work?

The sawed silicon wafers will be cleaned and afterwards the alkaline texturing process takes place. The texturing process will etch surface of silicon, that we obtain a surface with pyramids. This will reduce the reflection of the light to maximize the light absorption into the silicon material, leading to a higher efficiency of the solar cells.

Why is wet chemical processing used for high volume PV production?

Wet chemical processing is used for high volume PV production because of the low manufacturing cost, which allows solar cells to be competitive with non-renewable energy sources. Cost reduction measures are in great demand in the PV industry to allow grid parity to be reached.
