Taiwan solar cell manufacturers increase monocrystalline silicon PERC production
With the PERC (passivated emitter backside battery) improving the efficiency of monocrystalline silicon wafer production by 1%, the maximum efficiency is improved by about 0.6%. It is said that Taiwan manufacturers focus on the production of single crystal PERC batteries.
Huang Henghui, research manager at EnergyTrend, said: "PERC offers higher efficiency at a competitive cost, which has led to a surge in demand for this technology."
According to EnergyTrend, Taiwanese battery manufacturers have already used more PERC technology than other regional companies and have already produced about 1 GW of production.
Recently, NPD Solarbuzz Vice President Finlay Colville detailed in the PV-Tech guest blog that the global production capacity of PERC battery technology is expected to exceed 2.5GW by the end of 2014.
EnergyTrend said that Sunrise Global Solar Energy, a subsidiary of Sino-American Silicon, has recently become a leader in Taiwan's migration to PERC technology, but Motech and Gintech Energy. ) This technology is used in conjunction with Neo Solar Power, which is widely used by PV-Tech due to the order placement for PERC process equipment and the increased production of monocrystalline wafers by leading suppliers such as Longi Silicon in 2014. track.
Japan is considered to be the main market for PEC-based P-type monocrystalline silicon PERC cells due to its small roof and relatively high feed-in tariffs.
Product introduction
HHCMS-240 type Carbon Molecular Sieve
HHCMS-240 is a new kind of non-polar adsorbent. It is designed to extract nitrogen-rich gas from the air. It is suitable for separating nitrogen from the air.
The most notable features of the carbon molecular sieve are high gas-producing efficiency and low waste, especially nitrogen with a purity higher than 99.9%.
It is widely used in large air separation and sheet making equipment, and the application field covers the high-end aspects such as the storage and transportation of crude oil in yibi ships.

Pay attention to
1. The nitrogen production equipment can reduce the adsorption temperature to better show its excellent nitrogen production performance under conditions;
2. Pay attention to low temperature drying and seal preservation during storage;
