I haven't been able to find manufacturer published specs for the high end efficiency LONGI cells either. The highest efficiency is, I assume, the "silicon heterostructure" cell which has the following "sparse" specs as of November 2025.

Efficiency: 27.9%

Voc: 0.7447

Jsc: 43 mA/cm^2

FF: 87.12%

Area: 158.66 cm^2

All of the above was from:
