6 FAQs about [Schematic diagram of photovoltaic cell etching process]
What is etching process in solar cell processing?
Etching is a process which removes material from a solid (e.g., semiconductor or metal). The etching process can be physical and/or chemical, wet or dry, and isotropic or anisotropic. All these etch process variations can be used during solar cell processing.
Which etching sequence is used in solar cell processing?
Silicon etching is subdivided into acidic and alkaline etching sequences in solar cell processing (section Etching). Alkaline etching is mostly applied for monocrystalline (100) silicon wafers, whereas acid etching is used for fast texturing or polishing processes on multicrystalline substrates.
How long does it take to Etch A solar cell?
The wafers are moved horizontally on rolls through tanks, with an etching time of around 2 minutes per wafer. The solar cell efficiency depends strongly on the etching depth of the acidic texture. If the etching depth is too low, crystal defects remain and the open-circuit voltage, as well as the short-circuit current, are reduced.
How to etch a single crystalline silicon solar cell using plasma etching?
In texturing of silicon by plasma etching, fluorine-containing plasma such as F 2, CF 4 + O 2, CF 4 + N 2 O, SiF 4 + O 2, SF 6 + O 2 are used . The main motivation of this research work is to improve the efficiency of a single crystalline silicon solar cell.
What is the role of etching steps in PV production?
Their impact in both alkaline and acidic media including SC-1, SC-2, dHF, dHF-H 2 O 2, or dHF-O 3 enables minimizing of particle deposition. Driven by cost and environmental aspects the trend goes to biodegradable surfactants. Wet-chemical etching steps are an integral part in handling silicon for PV production.
How is silicon etching compared to solar cell manufacturing?
Industrially applied cleaning sequences are considered and compared with respect to solar cell manufacturing (section Cleaning of Silicon Surfaces). Silicon etching is subdivided into acidic and alkaline etching sequences in solar cell processing (section Etching).
