How efficient are Topcon solar cells?

Due to the potential for high theoretical limit efficiency as high as 28.7% and low cost , TOPCon solar cells have become one of the prospective technologies in the photovoltaic (PV) market . At present, the highest efficiency for n-TOPCon has achieved 26.4% on an area of 330.15 cm 2 at JinkoSolar .

How efficient are Topcon bifacial cells?

After optimizing the passivation process, the industrial-grade TOPCon bifacial cells reached an efficiency (Eff), Voc, Jsc, and FF values as high as 25.4%, 721 mV, 42.2 mA/cm 2, and 83.5%, respectively. 1. Introduction

How bifacial N-Topcon devices improve solar cell efficiency?

241.3 cm 2 -large bifacial n-TOPCon devices with 23.01% certified efficiency demonstrated. Using ≥ 150 nm of poly-Si and polished rear side improves the solar cell efficiency. 1-cell glass-glass laminates of the devices pass damp heat and thermal cycling tests. Roadmap to 25.5% efficiency presented.

What are N-Topcon solar cells?

The appeal of n-TOPCon solar cells is in the incorporation of rear passivating contacts consisting of n-type polycrystalline silicon (poly-Si) and interfacial SiO x films, which provide low recombination current density (J0) and contact resistivity (ρc) simultaneously .

What is the fill factor of N-Topcon solar cells?

a) Fill factor (FF) of the n-TOPCon solar cells with different tpoly, together with the FF without the impact of the series resistance (FFn), as well as the FF without the impact of both the series resistance and the non-unity ideality factor (FF0).
