Silicon Heterojunction Solar Cells

Silicon heterojunction solar cells (SHJ) is a promising candidate for cost-effective high-efficiency solar cells. The high performance is driven by a superior surface passivation provided by the solar cell structure where a thin silicon amorphous buffer layer separates the bulk from the highly recombinative metallic contacts.
