How are bifacial N-Pert Solar Cells fabricated?

Sci. Ed. 37 , 1056–1060 ( 2022) Cite this article The bifacial n -PERT (Passivated Emitter Rear Totally diffused) solar cells were fabricated using a simplified process in which the activation of ion-implanted phosphorus and boron diffusion were performed simultaneously in a high-temperature process.

Can n-type polysi passivating contacts be used in a bifacial solar cell?

Conclusions We presented studies of n-type polySi passivating contacts and their application on the back side of a high-performance bifacial n-type solar cell with fire-through screen-printed metallization, processed on 6″ Cz wafers. The cell design is tentatively called PERPoly (Passivated Emitter Rear Polysilicon contact).

What is the efficiency of a bifacial cell?

A best efficiency of 20.7% was achieved together with very high average cell Voc of 674 mV. As an added benefit, the cells are bifacial and with bifaciality factor >0.8.

What is the SIO x /n +-poly-Si process of N-Topcon solar cells?

Therefore, this study focuses on the SiO x /n +-poly-Si process of n-TOPCon solar cells, which consisted of screen-printed metallic contacts on both sides fabricated from 182 mm × 182 mm × 0.14 mm Cz-Si wafers through an industrial-type process with the fixed Ag/Al and Ag pastes.

How many patents have been granted to N-Pert bifacial module?

• Totally 31 IBC related patents, 16 granted, 11 under substantive examination and 4 accepted. n-PERT bifacial module 300Wp (STC). Average GHI 1052 W/m2. PV module average output: 295.3W Performance Ratio: 295.3/300*(1000/1052)=93.6%, measured at the input port of the string inverter.

How efficient is a cell with a monofacial contact?

Recent progress on cells with such contacts, achieving conversion efficiencies above 25% on small area cells , , and demonstrating in excess of 21% cell efficiency on 6″ monofacial cells , merit the need to investigate industrialization of the concept.
