4 FAQs about High-efficiency Israeli photovoltaic cell cabinet for tunnels

How efficient are tunnel-IBC solar cells on industrial CZ wafers?

Light IV curve of a record 90.25cm 2 tunnel-IBC solar cell. 5. Conclusion High performance tunnel-IBC cells show efficiencies of 25% on industrial Cz wafers. The absence of passivation degradation using the shadow mask technology is confirmed at the cell level, with a pseudo-fill factor exceeding 84%.

What are the design constraints of tunnel IBC solar cells?

The corresponding diffusion length exceeds 3 mm; consequently, the design constraints of the tunnel IBC are relaxed compared to standard homo-junction IBC solar cells which suffer usually from lower passivation quality (Jo,total >10fA/cm 2) [ , , ].

What is the pseudo-fill factor of a tunnel-IBC solar cell?

The pseudo-fill factor (pFF) is 84.7%, highlighting the high passivation quality of the solar cell. The difference between pFF and FF (3.2%) only depends on the series resistance of the solar cell. 3.2. R s model In order to simulate the series resistance of the tunnel-IBC solar cell, we use the 2-dimensional scheme as presented in Fig. 4.

How efficient are HJT solar cells?

The recombination at passivated contacts is minimized, achieving open-circuit voltage (V oc) of over 740 mV. In terms of front and back contacted architectures, the current efficiency record of HJT solar cells is held by the company Hanergy, reaching a V oc of 747 mV and an efficiency of 25.11% for a 244.45 cm 2 silicon HJT solar cell .
