Polycrystalline silicon

Polycrystalline silikoni ndi mawonekedwe a elemental silicon.Pamene chitsulo chosungunuka cha silicon chimalimba pansi
supercooling, maatomu a silicon amapangidwa mwa mawonekedwe a diamondi kuti apange ambiri
zitsulo za kristalo.Ngati ma crystal nuclei awa amakula kukhala njere za kristalo zokhala ndi mawonekedwe osiyanasiyana a kristalo, izi
mbewu za kristalo zimaphatikizana kupanga polycrystalline silicon..Mtengo wogwiritsira ntchito: kachitidwe kachitukuko ka solar
ma cell amatha kuwonedwa kuchokera kuzomwe zikuchitika masiku ano ma cell a dzuwa.

Silicon ya polycrystalline itha kugwiritsidwa ntchito ngati zopangira kukoka silicon imodzi ya crystal.Kusiyana pakati
Silicon ya polycrystalline ndi silikoni imodzi ya crystal imawoneka makamaka pazinthu zakuthupi.Mwachitsanzo,
The anisotropy of mechanical properties, kuwala katundu ndi matenthedwe katundu ndi kutali zoonekeratu kuposa
ya crystal silicon imodzi;ponena za mphamvu zamagetsi, madulidwe a silicon ya polycrystalline
crystal imakhalanso yocheperapo kuposa ya crystal crystal silicon, ndipo imakhalabe pafupifupi palibe conductivity.
Pankhani ya mankhwala, kusiyana pakati pa awiriwa ndi kochepa.Polycrystalline silicon ndi
silicon ya monocrystalline imatha kusiyanitsa ndi mawonekedwe awo, koma chizindikiritso chenicheni chimafunikira
kusanthula kuti mudziwe komwe kristalo imayendera, mtundu wa conductivity ndi resistivity ya kristalo.
