Gulu la solar panel

Panopa mphamvu ya dzuwa imagwiritsidwa ntchito ndi anthu ambiri.Muyenera kudziwa kuti ndizosavuta kugwiritsa ntchito.Ndi chifukwa cha zabwino zake zambiri zomwe zimakondedwa kwambiri ndi ogula ambiri.Mndandanda waung'ono wotsatirawu udzakufotokozerani mitundu ya mapanelo a dzuwa.

1. Maselo a dzuwa a polycrystalline silicon: Njira yopangira maselo a dzuwa a polycrystalline silicon ndi ofanana ndi maselo a dzuwa a monocrystalline silicon, koma photoelectric kutembenuka kwamphamvu kwa maselo a dzuwa a polycrystalline silicon ndi otsika kwambiri, ndipo kutembenuka kwa photoelectric kumakhala pafupifupi 12%.Pankhani ya mtengo wopanga, ndi yotsika mtengo kuposa ma cell a solar a monocrystalline silicon, zinthuzo ndizosavuta kupanga, kugwiritsa ntchito mphamvu kumapulumutsidwa, ndipo mtengo wake wonse ndi wotsika, motero wapangidwa kwambiri.

2. Amorphous silicon solar cell: Amorphous silicon Sichuan solar cell ndi mtundu watsopano wa solar cell woonda kwambiri womwe unawonekera mu 1976. Ndizosiyana kwambiri ndi njira yopangira monocrystalline silicon ndi polycrystalline silicon solar cell.Njirayi imakhala yosavuta komanso kugwiritsa ntchito zida za silicon ndizochepa kwambiri., mphamvu yogwiritsira ntchito mphamvu imakhala yochepa, ndipo ubwino wake waukulu ndikuti ukhoza kupanga magetsi ngakhale mumdima wochepa.Komabe, vuto lalikulu la amorphous silicon solar cell ndiloti kutembenuka kwa photoelectric kumakhala kochepa, mlingo wapamwamba wapadziko lonse ndi pafupifupi 10%, ndipo siwokhazikika mokwanira.Ndi nthawi yowonjezera, kutembenuka kwake kumachepa.

3. Maselo a dzuwa a Monocrystalline silicon: Kujambula kwa photoelectric kwa maselo a dzuwa a monocrystalline silicon ndi pafupifupi 15%, ndipo apamwamba kwambiri ndi 24%.Uku ndiye kusinthika kwapamwamba kwambiri kwazithunzi zamitundu yonse yama cell a solar, koma kunena kwake, kupanga kwake kumawononga ndalama zambiri kotero kuti sikunagwiritsidwe ntchito konsekonse.

4. Maselo a dzuwa ophatikizika ambiri: Ma cell a solar ophatikizika ambiri amatanthawuza ma cell a solar omwe sanapangidwe ndi zida za semiconductor imodzi.Pali mitundu yambiri ya kafukufuku m'mayiko osiyanasiyana, ndipo ambiri mwa iwo sanatukuke.Zipangizo za semiconductor zokhala ndi mipata yambiri yama gradient band (kusiyana kwa mphamvu pakati pa band conduction ndi valence band) zitha kukulitsa mawonekedwe owoneka bwino a mayamwidwe amphamvu yadzuwa, potero kuwongolera kusinthika kwazithunzi.
