Down-Conversion Phosphor

Kpolychem down-conversion phosphor can convert ultraviolet light (300–400 nm) into visible light (620–680 nm). It is highly compatible with most plastic and adhesive systems, characterized by strong fluorescence, high quantum efficiency, and excellent adaptability to various systems. It is widely used in solar cells, photovoltaic glass, plastics, adhesives, EVA, and POE granules, as well as in applications such as fluorescent markers, optical sensors, displays, and laser technologies, improving material visibility and functionality.

[Usage Methods]

Solar Cells:

Can be applied to the surface of solar cells to convert high-energy ultraviolet light into low-energy light, thereby improving the photoelectric conversion efficiency.

Antireflective Coating:

Combining antireflective liquid with down-conversion phosphor not only enhances the antireflection and UV light conversion effects but also improves photoelectric conversion efficiency by at least 1%.

Photovoltaic Glass:

Mix the down-conversion dispersion liquid with antireflective liquid.

Apply the antireflective and down-conversion dispersion liquid onto photovoltaic glass.

Use a sintering process to bake the antireflective and down-conversion coating onto the glass surface.
