There are two varieties of c-Si, polycrystalline and monocrystalline silicon, but monocrystalline is the only one considered for HJT solar cells since it has a higher purity and therefore more efficient. Amorphous silicon is used in thin-film PV technology and is the second most important material for manufacturing heterojunction solar cells.
HJT panels have lower temperature coefficient than conventional solar panels, ensuring high performance at elevated external temperatures. Life expectancy – On average, thin-film photovoltaic modules have a life expectancy of up to 25 years, while HJT solar cells can remain fully functioning well over 30 years.
