N {-} hivecrystalline silicon wafer proseces thiab txhawb nqa cov pa incer)- effecticic pv modules. Zus siv cov txheej txheem CZ thiab doped nrog phosphorus, nws nta a<100>Cov kev taw qhia saum npoo av, qis dislocation ntom (tsawg dua los yog sib npaug rau 500 cm⁻²), thiab n - hom conductivity. Nrog kev tiv thaiv ntau ntawm 1.0-7.0 ω ω. M12 Wafer qhov zoo geometry thiab zoo zoo zoo ua tau kev ua tau zoo hauv {} tiam siab {}} hwj chim modules.
