6 FAQs about [Etching of the Solar Photovoltaic Industry]
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.
Can etching process be used in industrial production of silicon solar cells?
This aspect is particularly relevant when considering the introduction of the process in the industrial production of silicon solar cells, as a less stable etching process would be more difficult to implement. Fig. 11. Effective reflectivity of MACE etched samples as function of reaction time with ρ = 0.916 and ρ = 0.944. Fig. 12.
Can metal-assisted chemical etching be used in solar cell industrial production?
Still, to be applied in the solar cell industrial production a light-trapping technique must be fully scalable and cost-effective. Metal-assisted chemical etching (MACE) is a very promising light-capture technique, that could become a standard method in the industrial production of crystalline silicon solar cells.
What is the etching process?
The etching process starts with the dip of the silicon wafers in the MACE solution. Since the chemical etching is exothermic and the reaction rate is dependents on the temperature, it is crucial to control and stabilize the etching temperature.
What is the etch rate of alkaline etch solutions?
The etch rate of alkaline etch solutions are generally lower than at he etch rates of acidic etching solutions. Consequently, alkaline etch processes are often performed at high temperatures (70-80 °C). Alkaline etching is typically anisotropic with an etch rate of 1-2 µm/min for low concentration (1-5% v/v) alkaline solutions.
What is a typical etch rate?
The typical etch rates are 2-4 µm/min at 6-10 °C. Due to the different grain orientations within the same multicrystalline silicon wafer, acidic etching is used to texture this type of material. Acidic solutions are also used to perform defect etching (e.g. Sopori etching ).
