Maselo a solar alemba mutu 1

maselo a dzuwa apangidwa kukhala m'badwo wachitatu, umene m'badwo woyamba ndi monocrystalline pakachitsulo dzuwa maselo, m'badwo wachiwiri ndi amorphous pakachitsulo ndi polycrystalline pakachitsulo maselo dzuwa, ndipo m'badwo wachitatu ndi mkuwa-zitsulo-gallium-selenide (CIGS) monga woimira wa woonda filimu pawiri maselo dzuwa.
Malingana ndi kukonzekera kwa batri pogwiritsa ntchito zipangizo zosiyanasiyana, maselo a dzuwa akhoza kugawidwa m'magulu otsatirawa.

Maselo a dzuwa a silicon amagawidwa kukhala ma cell a solar a monocrystalline silicon, ma cell a solar a polycrystalline silicon woonda-filimu ndi amorphous silicon woonda-filimu yama cell solar amitundu itatu.
Maselo a solar a Monocrystalline silicon ali ndi mphamvu zosinthira kwambiri komanso ukadaulo wokhwima kwambiri. Kutembenuza kwakukulu mu labotale ndi 23%, ndipo kupanga bwino ndi 15%, komwe kumagwirabe ntchito pazantchito zazikulu komanso kupanga mafakitale. Komabe, chifukwa cha kukwera mtengo kwa silicon ya monocrystalline, ndizovuta kwambiri kuchepetsa mtengo wake, kuti apulumutse zipangizo za silicon, kupanga filimu yochepetsetsa ya silicon yochuluka komanso filimu ya amorphous silicon yopyapyala monga njira ina ya monocrystalline silicon solar cell.
Polycrystalline pakachitsulo woonda-filimu maselo dzuwa ndi monocrystalline pakachitsulo dzuwa maselo, mtengo ndi otsika, pamene dzuwa ndi apamwamba kuposa amorphous pakachitsulo woonda-filimu maselo dzuwa, apamwamba kutembenuka dzuwa la labotale ndi 18%, kutembenuka dzuwa la kupanga mafakitale-ang'ono ndi 10%. Chifukwa chake, ma cell a solar a polycrystalline silicon awonda kwambiri posachedwa adzalamulira msika wama cell a solar.
Amorphous silicon woonda filimu ma cell solar ndi otsika mtengo, kulemera kopepuka, kutembenuka kwakukulu, kosavuta kupanga misa, ali ndi kuthekera kwakukulu. Komabe, chifukwa cha kuchepa kwa mphamvu ya photoelectric yomwe imapangitsa kuti zinthu ziziyenda bwino, kukhazikika sikuli kwakukulu, kumakhudza mwachindunji ntchito zake. Ngati titha kuthetsa vuto lokhazikika ndikuwongolera kuchuluka kwa kutembenuka, ndiye kuti amorphous silicon solar cell mosakayikira ndiye chitukuko chachikulu cha maselo adzuwa a mankhwala!
(2) Ma cell a solar opangidwa ndi mafilimu ambiri
Multi-compound woonda filimu solar cell zipangizo za mchere mchere, kuphatikizapo gallium arsenide mankhwala, cadmium sulfide, cadmium sulfide ndi mkuwa m'ndende selenium woonda filimu mabatire.
Cadmium sulfide, cadmium telluride polycrystalline woonda-filimu solar cell dzuwa ndi apamwamba kuposa sanali pini pakachitsulo woonda-filimu maselo dzuwa, mtengo ndi wotsika kuposa monocrystalline pakachitsulo maselo dzuwa, komanso zosavuta kupanga yaikulu, koma chifukwa cadmium ali ndi kawopsedwe mkulu, adzachititsa kwambiri kuipitsa kwa chilengedwe, kotero kuti silikoni bwino kwambiri ma cell, kotero kuti silikoni bwino kwambiri.
