## Daga Polysilicon zuwa Monocrystalline: Abin da “Semiconductor-Grade” Ke Nufi da Gaske a PV

**Silicon na matakin hasken rana da na semiconductor suna fitowa daga tsari ɗaya. Sun bambanta da kusan uku zuwa biyar nines na tsarki, da abin da waɗannan nines ke kashewa.** Ana faɗin polysilicon na photovoltaic yawanci a 6N–8N; kayan matakin lantarki suna farawa daga 9N har zuwa 11N–12N, tare da sarrafa ƙazanta na ƙarfe ɗaya-ɗaya a cikin kewayon sassa-da-biliyan maimakon sassa-da-miliyan. Wannan gibin shine dalilin da yasa masana'antun biyu ke raba ka'idodin kayan aiki amma kusan ba sa raba takardar ƙayyadaddun bayanai — kuma shine dalilin da yasa kalmar “matakin semiconductor” a kan tayin PV ta cancanci dubawa sosai kafin ka sanya hannu.

## Masana'antu Biyu, Farawa Ɗaya

Duk sarƙoƙin biyu suna farawa da polysilicon mai tsafta sosai, kuma dukansu suna yin sa haka. Tsarin Siemens da aka gyara yana ɗaukar silicon na matakin metallurgical, yana mai da shi trichlorosilane da hydrogen chloride, yana tsarkake shi ta hanyar distillation, sannan yana ajiye silicon na asali daga iskar da aka tsarkake a cikin reactor na rage hydrogen.
