6 FAQs about [Dual wave components and perc]

How is the PERC rear side modeled?

The PERC rear side is electrically modeled by assuming an effective SRV (SRV = 30 cm/s), which lumps the effect of the local Al BSF contacts and the passivated rear side. Apart from sPERC, all structures are (quasi-)one dimensional. For sPERC, we assume the local contact openings as lines at the front with 30 μm width and vary the contact pitch.

Can metalens achieve dual-wavelength multifunctionality?

Technological advancements have enabled the active control of electromagnetic waves. Metalenses, known for their precision in wavefront shaping and functional versatility, represent a breakthrough in optical modulation. This study addresses the challenge of achieving dual-wavelength multifunctionality in metalens design.

How does synchronised dual-wavelength mode-locking work?

In synchronised dual-wavelength mode-locking, the pulse components at the two wavelengths tend to walk-off under the influence of dispersion. However, the loss generated by the SA continuously removes the part of the pulse that has walked off and hence effectively binds the two wavelengths together.

How PERC enables dielectric surface passivation?

s PERC enables dielectric surface passivation. Basically, it features a structured PERC front side with a selective emitter. The full-area emitter is passivated by a dielectric insulating SiO 2 /SiN x layer (shown in Figure 1 .2), and contact to the top cell is made by a TCO through local openings in the passivation layer at the deep n ++ -emitter.

How many MV does a P[E]RC emitter produce?

Starting with the quite simple P [E]RC device (concept 1), we see that a highly doped, opaque emitter (P46, red) is needed to achieve a modest Voc of around 654 mV (Figure 7B) for the case that the TCO interconnection layer provides poor surface passivation.

Can PERC technology be used as a tandem device?

However, the pathway towards an optimized tandem device based on PERC technology (Pero-PERC) needs to be further investigated, which among other factors includes the phosphorus-diffused front emitter and the interconnection layers towards the top cell.
