hjt

HJT is an acronym that may refer to several topics. In energy technology, it most commonly denotes heterojunction with intrinsic thin layer, a solar cell architecture that combines a crystalline silicon wafer with ultrathin layers of hydrogenated amorphous silicon on both faces.

The intrinsic layer passivates the silicon surface, reducing recombination and enabling high open-circuit voltages. The structure can deliver high efficiencies and exhibits favorable temperature coefficients, contributing to robust performance under real-world conditions. Manufacturing typically involves low-temperature deposition of amorphous silicon by chemical vapor deposition and is designed to be compatible with conventional silicon wafer production lines, aiding implementation.

Outside photovoltaics, HJT can serve as an initialism for other organizations, programs, or terms that share the same letters. As with many acronyms, the exact meaning depends on context, and HJT may refer to entities not related to solar technology.
