Solar photovoltaic silicon wafer "wear new clothes" -- ultrasonic spraying

Solar photovoltaic silicon wafer "wear new clothes" - photovoltaic cell - YMUS ultrasonic spraying

Photovoltaic (PV) cells are also known as solar cells. A group of solar photovoltaic panels or solar photovoltaic modules together with solar wiring, circuit breakers, solar chargers, batteries, solar inverters and other downstream equipment constitute a photovoltaic system.

Photovoltaic "Photo" refers to photons or electromagnetic waves in the light or visible spectrum. "Volt" refers to the potential difference, which causes electrons to flow and create an electric current. Photovoltaic refers to the generation of electricity when struck by a light source (natural or artificial light source with sufficient wavelength and energy) on the surface of a photoelectric material.

Common solar cell - thin film solar cell

Thin-film solar cells (TFSCS) - Instead of using classic silicon crystals (which are thick, hard and brittle and crack under bending pressure), photovoltaic materials are deposited very thinly on the substrate, making them more portable and flexible. Thin film panels are simple to make, uniform, attractive to look at, and flexible. The efficiency variable depends on the photovoltaic material. Thin film panels can be composed of a variety of materials, the main choice is amorphous silicon (A-Si), the most common types are cadmium telluride (CdTe) and copper indium gallium selenide (CIS/CIGS).

How to coat the photosensitive coating of solar silicon wafer?

YMUS ultrasonic spraying system coating solar silicon wafer, the photosensitive adhesive solution evenly coated on the silicon wafer. YMUS-K ultrasonic atomizing nozzle series makes the coating uniformity > 95%, and the evenly atomized slurry falls on the substrate flexibly.
