Introduction of HJT
Al-IZZ Solar (IZH)
BRIEF INTRODUCTION OF SILICON HT CELLS
A PV Cell Technology Platform
Hetero Junction with Intrinsic Thin-Layer ( short name as HJT
or HIT) solar cells are based on N-type silicon wafer, with two
different layers which are Silicon based film and TCO film, this is
the key for HJT solar cell.
- 28.5% Theoretical efficiency , 25.5% Massive production potential;
- A better P-N structure compared to normal solar cell;
- Optimized padsivation structure, longer lifetime of carrier;
- Low Temp(250 dec) & Low Energy Consumption processing, suitable for thinner wafer.
Tandem Cell is an update for the thin-film Cell industry
Equipment land Covering ~3.2%
Equipment invest CAPEX~13%
Efficiency improve 5%, Module cost reduce 15.2%
- 42.5% Theoretical efficiency, 30%+ Massive production potential;
- 15%+ per watt Cost reduction;
- Compatible with current HT production line;
- Industrialized in 2025.
