What is the performance of PERC technology on polycrystalline and monocrystalline solar cells?

At present, PERC technology has become the main method for increasing the efficiency of P-type solar cells, but the performance of PERC technology on polycrystalline and monocrystalline cells is different.

How are PERC solar cells made?

Poly PERC solar cells are manufactured by blending or melting different silicon fragments together, while mono PERC solar cells are manufactured using a single silicon crystal, free from grain limits (2D defects).

Will PERC become a standard technology configuration for c-Si cells?

In fact, in the next one to three years it is estimated that PERC will become the standard technology configuration for c-si cell manufacturers. Many major cell manufacturers – such as Q CELLS, SolarWorld and Trina Solar – have already begun mass production of PERC solar cells.

What is a PERC solar cell (or photovoltaic cell)?

PERC (PPassivated Emitter and Rear Cell), the passivated emitter and back cell technology, was first proposed by Australian scientist Martin Green in 1983 and is now becoming a new generation of conventional technology for solar cells.

How efficient are PERC solar 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.

How PERC technology can improve the efficiency of PV cells?

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.
