Hauv lub hnub ci PV kev lag luam, wafer thev naus laus zis hloov los ntawm kev hloov pseudo square156.75x156.75mm M2 kom loj dua ntawm wafer ntau thiab tsawg ntawm daim duab tag nrho 158.75x158.75mm thiab qhov no suav nrog p-hom thiab n-hom mono-Si wafers.
Lub xeev ntawm cov kos duab Puv Ncig Toj Siab Mono Wafers tau muab lub teeb pom kev zoo rau tib theem ntawm kev siv ntau tshaj los ntawm kev nthuav tawm cov square ntsuas. Cov xaim txuas yog qhov xwm txheej tag nrho kom lawv haum rau PV module hauv kev ua kom zoo.
