Mphamvu ya kuwala kwa dzuwa ingasinthidwe mwachindunji kukhala magetsi pogwiritsa ntchito maselo a solar photovoltaic, omwe amadziwikanso kuti maselo a photovoltaic. Maselo a solar amaphatikizidwa m'njira zinazake kuti apange ma module a photovoltaic, omwe amapangidwira kukwaniritsa zofunikira zinazake malinga ndi mphamvu yotulutsa yoyesedwa ndi mphamvu yotulutsa. Kukula kwa ma array omwe amapanga gawo la solar module kumatha kusiyana kwambiri, kutengera kukula kwa chomera chamagetsi cha photovoltaic.
Njira zamakono zopangira vacuum laminating ndi pulse welding zimatsimikizira moyo wautali wa ntchito ya ma photovoltaic modules, omwe amagwiritsa ntchito ma mono crystalline kapena poly crystalline silicon photovoltaic cells ogwira ntchito bwino kwambiri, galasi lotenthetsera kwambiri, ndi chimango cha aluminiyamu cholimba ndi dzimbiri, pakati pa zipangizo zina.
Kodi mungandiuze mitundu yambiri ya maselo a dzuwa?
1. Maselo a dzuwa olumikizana ofanana, maselo a dzuwa olumikizana osiyana, ndi maselo a dzuwa a Schottky onse ndi magulu omwe angathe kugawidwa kutengera kapangidwe kake.
2. Maselo a dzuwa opangidwa ndi zinthu zosiyanasiyana akhoza kugawidwa m'magulu osiyanasiyana, kuphatikizapo silicon, mankhwala achilengedwe, pulasitiki, nanocrystalline yodziwika bwino, inorganic compound semiconductor, ndi maselo a dzuwa achilengedwe.
3. Zingagawidwe m'magulu a maselo a solar achikhalidwe ndi maselo a solar a excitonic kutengera njira yosinthira kuwala kwa dzuwa.
Malinga ndi magulu a mitundu, pali mitundu inayi ya maselo a photovoltaic: amorphous silicon, polycrystalline silicon, copper indium selenide, gallium arsenide, ndi monocrystalline silicon.
Maselo a dzuwa opangidwa ndi silicon ya monocrystalline
Katswiri waposachedwa kwambiri mu ukadaulo wa maselo a photovoltaic, maselo a monocrystalline silicon amapereka kuphatikiza kwabwino kwambiri kwa kukula, magwiridwe antchito, komanso moyo wautali. Kuchuluka kwa kusintha kwa maselo a monocrystalline silicon photovoltaic ku China kwafika pa 16.5%, ndipo mphamvu yayikulu kwambiri ya labotale yopitilira 24.7%. Zipangizo zopangira maselo a solar awa nthawi zambiri zimakhala ndodo za silicon zokhala ndi chiyero cha 99.9999% komanso silicon ya monocrystalline yapamwamba kwambiri.
Maselo owoneka bwino a silicon photovoltaic
Mtundu umodzi wa selo la dzuwa ndi selo la polycrystalline silicon photovoltaic. Ndalama zopangira zachepetsedwa kwambiri chifukwa cha kusintha kwa zinthu za polycrystalline silicon m'malo mwa njira yojambulira monocrystalline silicon, zomwe zachepetsa kwambiri nthawi yopangira. Kuchepa kwa kugwiritsidwa ntchito kwa plane pambuyo pa kupangidwa kwa PV module kumachitika chifukwa cha maselo ozungulira a PV omangidwa kuchokera ku ndodo za monocrystalline silicon komanso kuti ndodo ndi maselo onse ndi ozungulira. Pali phindu logwiritsa ntchito maselo a polycrystalline silicon photovoltaic m'malo mogwiritsa ntchito maselo a monocrystalline silicon.
Maselo a dzuwa osasinthika a silika
Mtundu watsopano wa selo lopyapyala lopangidwa kuchokera ku silicon yopanda mawonekedwe ndi selo lopanda mawonekedwe la silicon photovoltaic. Selo la semiconductor lomwe lili ndi kapangidwe ka kristalo yopanda mawonekedwe limadziwika kuti silicon yopanda mawonekedwe. Limatha kupanga maselo a dzuwa okhala ndi makulidwe a micron imodzi yokha, omwe ndi ofanana ndi maselo a silicon a monocrystalline a 300 nm. Poyerekeza ndi silicon ya polycrystalline ndi monocrystalline, lili ndi njira yosavuta kwambiri yopangira, limagwiritsa ntchito zinthu zochepa za silicon, ndipo limagwiritsa ntchito mphamvu zochepa pa unit iliyonse.
Maselo a photovoltaic opangidwa ndi mkuwa, indium, ndi selenide
Filimu ya semiconductor imayikidwa pagalasi kapena zinthu zina zotsika mtengo kuti apange maselo a dzuwa a mkuwa-indium-selenium. Zosakaniza zazikulu zomwe zimagwiritsidwa ntchito ndi ma semiconductor a mkuwa, indium, ndi selenium. Kukhuthala kwa filimu ya pafupifupi l/100 ndikofunikira pamaselo a monocrystalline silicon photovoltaic chifukwa cha kuthekera kwabwino kwambiri koyamwa kuwala kwa mabatire a mkuwa wa indium selenium.
Maselo a Dzuwa Ochokera ku Gallium Arsenide
Maselo a silicon a amorphous photovoltaic, omwe ndi batire yopyapyala, amagwiritsa ntchito silicon yopanda mawonekedwe ngati chinthu chachikulu chomwe amamangira. Semiconductor yokhala ndi kapangidwe ka kristalo yopanda mawonekedwe imadziwika kuti silicon yopanda mawonekedwe. Imatha kupanga maselo a dzuwa okhala ndi makulidwe a micron imodzi yokha, omwe amafanana ndi maselo a silicon a monocrystalline a 300 nm. Pali kuchepa kwakukulu kwa kugwiritsa ntchito mphamvu ya unit komanso kusavuta kwa njira yopangira poyerekeza ndi njira zina zogwiritsira ntchito polycrystalline kapena monocrystalline silicon.
Maselo a polima a photovoltaic
Selo ya polymer photovoltaic cell, yomwe ndi multilayer composite yofanana ndi chipangizo choyendetsera zinthu cha PN chosapangidwa ndi zinthu zachilengedwe, imagwiritsa ntchito ma polima a redox okhala ndi mphamvu zosiyanasiyana za redox.
Ubwino ndi kuipa kogwiritsa ntchito maselo a photovoltaic
Ubwino wake:Palibe chiopsezo cha kuchepa mphamvu, kwenikweni sichikuipitsa, sichidalira kugawa kwa zinthu m'malo osiyanasiyana, chingapangidwe pafupi ndi malo opangira magetsi, chili ndi mphamvu zambiri, ogwiritsa ntchito ake ndi osavuta kuwalandira m'maganizo, chimapereka mphamvu kwa kanthawi kochepa, ndipo makina opangira magetsi ali ndi mbiri yabwino yodalirika.
Mbali zoyipa:Kupatula pa mtengo wokwera wa zomangamanga ndi kuchuluka kwa mphamvu zochepa zomwe zimagawidwa, nyengo zinayi, usana/usiku, mitambo/dzuwa, ndi zinthu zina zanyengo zonse zimakhudza mphamvu zomwe zimasonkhanitsidwa.
