Mtundu wa maselo a dzuwa chaputala 1

Ma cell a solar apangidwa m'badwo wachitatu, womwe m'badwo woyamba ndi monocrystalline silicon solar cells, m'badwo wachiwiri ndi amorphous silicon ndi polycrystalline silicon solar cells, ndipo m'badwo wachitatu ndi copper-steel-gallium-selenide (CIGS) monga woyimira ma cell a solar compound a film.
Malinga ndi kukonzekera kwa batri pogwiritsa ntchito zipangizo zosiyanasiyana, maselo a dzuwa akhoza kugawidwa m'magulu otsatirawa.

Maselo a dzuwa a silicon amagawidwa m'magulu atatu: maselo a dzuwa a silicon monocrystalline, maselo a dzuwa a polycrystalline silicon thin-film ndi maselo a solar a amorphous silicon thin-film.
Maselo a dzuwa a monocrystalline silicon ali ndi mphamvu yosinthira kwambiri komanso ukadaulo wokhwima kwambiri. Mphamvu yosinthira kwambiri mu labotale ndi 23%, ndipo mphamvu yopangira ndi 15%, yomwe ikadali yodziwika bwino pantchito zazikulu komanso kupanga mafakitale. Komabe, chifukwa cha mtengo wokwera wa monocrystalline silicon, n'kovuta kuchepetsa mtengo wake kwambiri, kuti tisunge zinthu za silicon, kupanga filimu yopyapyala ya silicon yambiri komanso filimu yopyapyala ya silicon yopanda mawonekedwe ngati njira ina m'malo mwa maselo a dzuwa a monocrystalline silicon.
Maselo a dzuwa a silicon thin-film solar cells ndi ma solar cell a silicon monocrystalline, mtengo wake ndi wotsika, pomwe magwiridwe antchito ndi apamwamba kuposa ma solar cell a silicon thin-film solar cells, mphamvu yapamwamba kwambiri yosinthira ma cell a labotale yake ndi 18%, mphamvu yosinthira ma cell a mafakitale ndi 10%. Chifukwa chake, ma solar cell a polycrystalline silicon thin-film solar cells posachedwa adzalamulira msika wa ma solar cells.
Maselo a dzuwa a silicon thin film solar cells ndi otsika mtengo, opepuka, osinthika kwambiri, osavuta kupanga zinthu zambiri, ali ndi kuthekera kwakukulu. Komabe, chifukwa cha kuchepa kwa mphamvu ya photoelectric yomwe imabwera chifukwa cha zinthu zake, kukhazikika sikukwera kwambiri, zomwe zimakhudza mwachindunji momwe amagwiritsidwira ntchito. Ngati tingathe kuthetsa vuto la kukhazikika ndikukweza kuchuluka kwa kutembenuka, ndiye kuti maselo a solar a silicon a amorphous mosakayikira ndiye chitukuko chachikulu cha maselo a solar a chinthuchi!
(2) Maselo a dzuwa opyapyala okhala ndi mafilimu ambiri
Zipangizo zama cell a solar okhala ndi filimu yopyapyala yambiri zomwe zimagwiritsidwa ntchito popanga mchere wosapangidwa, kuphatikizapo gallium arsenide compounds, cadmium sulfide, cadmium sulfide ndi mabatire a selenium thin film omwe amamangidwa ndi mkuwa.
Cadmium sulfide, cadmium telluride polycrystalline thin-film solar cell efficient ndi yapamwamba kuposa ma solar cell a silicon thin-film non-pin, mtengo wake ndi wotsika kuposa ma solar cell a silicon monocrystalline, komanso ndi osavuta kupanga, koma chifukwa cha cadmium ili ndi poizoni wambiri, zomwe zimayambitsa kuipitsa chilengedwe, kotero si njira yabwino kwambiri yopangira ma solar cell a silicon.
