4 FAQs about Perc component attenuation

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.

Why do PERC+ cells not exhibit voids?

The PERC+ Al fingers reduce the Al contact height by about 7 µm which is the reason why PERC+ cells do not exhibit voids in contrast to PERC cells .

What is the conversion efficiency of PERC cells?

The full-area Al-BSF with Seff,rear around 400 cm/s and Rrear around 65% limited the conversion efficiency of Al-BSF cells to about 18.5%. Due to the dielectric rear passivation, PERC cells exhibited a much lower Seff,rear around 50 cm/s and a higher Rrear around 90% and hence demonstrated conversion efficiencies close to 20%.

What is PERC module specification?

Table 1 Module specification. For PERC, monocrystalline PV panel experiments are performed in two steps. The STC conditions are characterized by 1000 W/m 2 of solar irradiance with cell temperature of 25 °C. Primarily, the experiment is conducted under no shading conditions. The electrical parameters and characteristics are recorded.
