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 to develop a low-temperature (200°C) PECVD process to reduce the energy cost by depositing the amorphous silicon layer required for both sides of the silicon wafer, allowing thin-film silicon wafers to be processed and used in front 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.
Polyvinyl Chloride (PVC) waterproof membrane is a new polymer waterproof membrane which is made from polyvinyl chloride resin, and mixed with plasticizer, filler, antioxygen, ultraviolet absorber and other auxiliaries. we adopts automatic mixing of raw material, double-screw extruder and delicate three-roller calender equipment in the PVC membrane production. PVC waterproof membrane features dimensional stability and high tensile strength, being a best choice for many civil and industrial projects. PVC waterproof membrane mainly falls into two categories: Homogeneous & Reinforced, each with different thickness specifications. Reinforced PVC waterproof membrane employs a fabric reinforced layer in the middle, it enhances the breaking and tear strength.
