Ag Alloying

Ag Incorporation with Controlled Grain Growth Enables 12.5% Efficient Kesterite Solar Cell with Open Circuit Voltage Reached 64.2% Shockley-Queisser Limit
The large open-circuit voltage deficit (V-oc,V-def) is the key issue that limits kesterite (Cu2ZnSn(S,Se)(4), [CZTSSe]) solar cell …
