A mass-production efficiency of 21.60% for PERC p-type mono cells has been achieved at TongWei Solar; cell efficiency has a narrow distribution band in mass production, demonstrating excellent process stability and quality reliability. ALD aluminium oxide technology yields outstanding
However, in order to achieve 22%+ efficiency for PERC solar cells in mass production, it is noted that further investigation regarding passivation and emitter doping processes is required, and that the metallization process needs to be optimized and high-quality wafers are necessary.
Passivated emitter and rear cell (PERC) technology can significantly increase the absolute efficiency of PV cells by over 1.2%. Since PERC processing is also compatible with current cell processing, and does not incur overly high manufacturing costs, many PV manufacturers are focusing on developing the industrialization technologies for PERC cells.
PERC solar cells in TongWei’s main efficiency band were used in the standard 60-cell modules, resulting in over 300W per module on average. SolarWorld and Trina Solar have both reported cell conversion efficiencies above 22% for their industrialized screen-printed PERC solar cells.
Our standardized photovoltaic power generation and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
