Meyerburger and CSEM Open Heterojunction Solar Cell Pilot Line

Meyer Burger, a leading supplier of photovoltaic equipment, officially launched its Heterojunction (HJ) solar cell pilot line with CSEM's Hauterive subsidiary Meyer Burger Research AG in Neuchatel, Switzerland.

The pilot line is part of an extensive Swiss-Inno HJ technology project that also involves the Swiss Federal Ministry of Energy and the Neuchâtel administrative district. Meyerberg is committed to attracting photovoltaic manufacturers to adopt their jointly developed heterojunction technology A key part of the mass production.

Peter Pauli, CEO of the Meyerburg Group, stated: "The industrial production of high-performance solar cells is the center of photovoltaic production. The Swiss-Inno HJT project promotes the further development of a forward-looking, high-efficiency battery technology. Together with CSEM, we will further optimize important economic advantages, such as reducing production costs and increasing energy production at the same time, thereby reducing solar energy costs in the long run."

The technology partner pointed out that the pilot line had a production capacity of 600 kilowatts. Heterojunction cells were fabricated into modules and tested in the laboratory and in the field.

The goal of further process optimization is to achieve a 21% PV module efficiency, but the production cost is lower than 0.6 CHF per watt (US$ 0.62 per watt). It is said that the HJT battery will achieve more than 22% efficiency under laboratory conditions.

Meyerburger and ETH Lausanne collaborate on the development of a low-temperature (200°C) PECVD process to reduce the energy cost by depositing amorphous silicon layers on both sides of silicon wafers, enabling thin-film silicon wafers to be processed and used in positive contact. Pretty little silver.

The heterojunction cell includes two ultra-thin amorphous silicon layers that create a heterojunction between the N-type monocrystalline silicon wafer and the two amorphous silicon layers, providing improved light capture and conversion efficiency.

Calcium Fluoride Lens

Calcium Fluoride Plano-Convex Lenses are ideal for demanding applications that require superior performance from the ultraviolet through the mid-wave infrared spectra.Calcium Fluoride PCX Lenses` low refractive index, high laser damage threshold, and low axial and radial-stress birefringence are highly suitable for use with Excimer lasers or for integration into infrared systems. Additionally, calcium fluoride features low solubility and offers superior hardness to comparable fluoride-based substrates, making these PCX lenses capable of withstanding harsh environments and exposure to the elements.
