Pakati pa kusintha kwa mphamvu zobiriwira, Building-Integrated Photovoltaics (BIPV) ikupita patsogolo ngati chinthu chofunikira kwambiri pakukula kokhazikika mumakampani omanga. Pakati pa ukadaulo watsopano, galasi la dzuwa la cadmium telluride (CdTe) limadziwika ndi luso lake lapamwamba, kukongola kwake, komanso mawonekedwe ake ochezeka ndi chilengedwe, zomwe zimapangitsa kuti likhale yankho lodziwika bwino pakugwiritsa ntchito BIPV.
1. Kugwira Ntchito Kochepa Kwambiri
Galasi la CdTe, lodziwika bwino chifukwa cha mphamvu zake zabwino zosinthira magetsi pogwiritsa ntchito kuwala, likukhala chinthu chofunikira kwambiri mu gawo la BIPV. Pogwiritsa ntchito filimu yopyapyala ya cadmium telluride ngati gawo la kuwala kwa dzuwa, limasintha kuwala kwa dzuwa kukhala magetsi bwino. Poyerekeza ndi maselo a dzuwa achikhalidwe okhala ndi silicon, galasi la CdTe limagwira ntchito bwino ngakhale m'malo opanda kuwala, zomwe zimapangitsa kuti nyumba zikhale ndi mphamvu yodalirika komanso yokhazikika.
Kugwiritsa ntchito magalasi a dzuwa a CdTe m'nyumba zambiri sikuti kumakwaniritsa zofunikira za magetsi zokha komanso kungathandizenso kubwezeretsanso mphamvu yochulukirapo mu gridi, kuonetsetsa kuti mphamvu imagwiritsidwa ntchito bwino. Njira yogwiritsira ntchito mphamvu imeneyi imathandiza kuchepetsa kugwiritsa ntchito mphamvu ndi mpweya woipa, zomwe zimathandiza kuti nyumba zobiriwira zipitirire patsogolo.
2. Kugwira Ntchito Kwambiri kwa Kutentha
Maselo a dzuwa a CdTe thin-film solar ali ndi coefficient yotsika kutentha, zomwe zimasonyeza kuti amatha kusinthasintha bwino ndi malo otentha kwambiri. Ngakhale nthawi yachilimwe yotentha, maselowa amakhalabe ogwira ntchito bwino kwambiri koma ntchito yawo siigwira bwino ntchito. Izi zimapangitsa maselo a CdTe thin-film kukhala njira yabwino kwambiri yopangira mphamvu m'malo otentha, zomwe zimathandiza kwambiri pa nyumba zobiriwira komanso ntchito za BIPV.
3. Moyo Wautali ndi Kukhazikika
Maselo a dzuwa a CdTe thin-film amakhalanso odziwika bwino chifukwa cha kulimba kwawo komanso kukhazikika kwawo m'malo akunja. Malinga ndi mayeso ochokera ku National Renewable Energy Laboratory (NREL), ma module a CdTe adasunga 88% ya mphamvu zawo zoyambirira pambuyo pa zaka 27 zogwira ntchito (1995-2021), ndi kuwonongeka kwa 12% kokha. Mosiyana ndi zimenezi, ma module a silicon a crystalline amataya mphamvu pafupifupi 20% panthawi yomweyi. Kukhalitsa kwamphamvu kumeneku kumapangitsa maselo a CdTe kukhala gwero lodalirika la mphamvu yokhazikika ya nyumba zobiriwira ndi BIPV.
4. Kugwirizana Kwambiri ndi Zomangamanga
Chimodzi mwa mphamvu zazikulu za galasi la CdTe ndi kapangidwe kake kosinthika, komwe kamagwirizana ndi luso la akatswiri omanga nyumba komanso zomwe eni nyumba amakonda. Kaya ndi mtundu, kapangidwe, kapena kukula, galasi la CdTe lingapangidwe kuti ligwirizane bwino ndi kukongola kwa nyumbayo. Kusinthasintha kumeneku kumalola galasi la CdTe kuti ligwire ntchito osati ngati gwero la mphamvu zokha komanso ngati chinthu chopangira, kukulitsa magwiridwe antchito komanso mawonekedwe a nyumbayo.
5. Kutumiza Kwabwino Kwambiri kwa Kuwala
Ma module a dzuwa a CdTe amaphatikiza cadmium telluride ndi galasi loyendetsa magetsi, zomwe zimapereka kuwala kothandiza komanso kukwaniritsa zosowa za masana a nyumbayo. Ma module awa amapezeka mumitundu yosiyanasiyana, amatsimikizira kufalikira kwa kuwala kofanana, kukulitsa mgwirizano wawo wowoneka bwino komanso wothandiza ndi kapangidwe ka nyumbayo.
6. Chitetezo Chapamwamba
Ma module achikhalidwe a dzuwa, akaikidwa mumthunzi pang'ono pakapita nthawi, amatha kuvutika ndi zotsatira za malo otentha, komwe kutentha kwambiri komwe kumachitika chifukwa cha mphamvu yamagetsi yapamwamba kumatha kuchepetsa magwiridwe antchito ndikuchepetsa nthawi ya moyo wa makina. Nthawi zambiri, izi zitha kubweretsa zoopsa zamoto. Ma module a CdTe, omwe ali ndi mphamvu yamagetsi yochepa komanso kutentha kochepa, sawonetsa zotsatira zochepa za malo otentha, zomwe zimapangitsa kuti makina azikhala otetezeka komanso azikhala olimba.
7. Kudalira Kochepa Kwambiri
Ma module a CdTe amapambana kwambiri pakuyamwa kwa kuwala kosiyanasiyana, zomwe zimapangitsa kuti asadalire kwambiri ngodya yoyika. Ngakhale pansi pa ngodya zazikulu, ma panel a CdTe amakhala ndi mphamvu zambiri poyerekeza ndi ma module ena, zomwe zimapangitsa kuti mphamvu zambiri zisinthe m'mikhalidwe yosiyanasiyana yoyika. Izi zimapangitsa kuti ma panel a CdTe azisinthasintha komanso azisinthasintha mu ntchito za BIPV.
8. Ubwino wa Zachilengedwe ndi Kukhazikika
Magalasi a dzuwa a CdTe amapangidwa pogwiritsa ntchito zipangizo ndi njira zosamalira chilengedwe, mogwirizana ndi zolinga za chitukuko chokhazikika. Poyerekeza ndi maselo a dzuwa achikhalidwe omwe amagwiritsa ntchito silicon, kupanga kwa CdTe kumapanga zinyalala zochepa ndipo kumakhala ndi malo ochepa osungira chilengedwe. Kuphatikiza apo, nthawi yayitali yogwira ntchito yake imatsimikizira kuti imagwira ntchito bwino pakapita nthawi, kuchepetsa kufunikira kosintha zinthu pafupipafupi ndikuchepetsa kugwiritsa ntchito zinthu ndi kuwononga chilengedwe.
Mwachidule, galasi la dzuwa la CdTe likuyimira yankho lamphamvu komanso lokhazikika la BIPV, lomwe limapereka magwiridwe antchito, kusinthasintha, chitetezo, komanso ubwino wa chilengedwe pa zomangamanga zamakono zobiriwira.
