Hyundai Solar Cell Technology

Hyundai PERL cells are high-efficient monocrystalline cells which adopt LBSF (Local Back Surface Field) technology on the back side. PERL technology provides ultra-high efficiency with better performance in low sunlight. This higher efficiency allows installation capacity in more limited space.

Front Shallow Emitter Structure
Enhanced short wavelength response

Passivation and Back Reflect Layer
Enhanced long wavelength response

Local Back Surface Field Structure
Minimization of back contact area

Both LID (Light Induced Degradation) and PID (Potential Induced Degradation) are strictly eliminated to ensure higher actual yield during lifetime.
