Tangoganizirani dziko limene ma solar panels amasakanikirana bwino ndi madenga, akujambula kuwala kulikonse kwa dzuwa ndi mphamvu yosayerekezeka. Izi si maloto akutali koma zenizeni zomwe zikukulirakulira chifukwa cha ma solar cell a BC. Mwachidule, Lumikizanani ndi ma solar cell, ukadaulo wa BC ukusinthiratu makampani opanga ma solar ndi kapangidwe kake katsopano komanso magwiridwe antchito apamwamba. Tiyeni tifufuze zodabwitsa za ma solar cell a BC ndi tsogolo lawo labwino.
Kapangidwe Kabwino ka Maselo a Dzuwa a BC
Ma cell a solar a BC, kapena ma cell a solar a Back Contact, ndi chitsanzo chabwino cha kapangidwe katsopano mu mphamvu ya dzuwa. Tangoganizirani izi: zolumikizirana zonse zachitsulo ndi malo olumikizirana omwe nthawi zambiri amadzaza pamwamba pa selo la solar zimasunthidwa kumbuyo. Kapangidwe kabwino kameneka kamachotsa mizere yoyipa yomwe imatseka kuwala kwa dzuwa, zomwe zimathandiza selo kuyamwa kuwala kulikonse. Zotsatira zake? Selo la solar lokongola komanso logwira ntchito bwino lomwe limatenga kuwala kwa dzuwa kwambiri ndikulisintha kukhala mphamvu bwino.
Ukadaulo wa BC si chitukuko chokhachokha koma ndi sitepe yosinthika yomwe imamangidwa pa ukadaulo womwe ulipo kale. Mwa kubwereka zinthu zabwino kwambiri kuchokera kwa omwe adalipo kale ndikuziphatikiza mu mawonekedwe atsopano komanso okonzedwa bwino, maselo a dzuwa a BC amakwaniritsa bwino kwambiri magwiridwe antchito.
Kuchita Bwino Komwe Kumawala Kwambiri
Kuchita bwino ndiye maziko a ukadaulo wa dzuwa, ndipo ma solar cell a BC akukhazikitsa miyezo yatsopano. Ma Perc (Passivated Emitter ndi Rear Cell) amakwanitsa kusintha pafupifupi 20-22% ya kuwala kwa dzuwa kukhala magetsi, pomwe ma Topcon (Tunnel Oxide Passivated Contact) amakankhira chiwerengerocho pafupifupi 23%. Komabe, ma solar cell a BC amapititsa patsogolo ntchito yawo ndi 24.5% ndipo 27-29% ya ntchito zawo zoyesera. Kuwonjezeka kwa 2-3% kuposa ma solar cell a N-TOPCon ndi kusintha kwakukulu, komwe kumapereka mwayi waukulu muukadaulo wa dzuwa.
Symphony of Technologies
Chomwe chimapangitsa ukadaulo wa BC kukhala wokopa kwambiri ndi kusinthasintha kwake. Ma cell a dzuwa a BC amatha kugwirizana ndi ukadaulo wina wotchuka monga Perc, TOPCon, ndi HJT (Heterojunction Technology) kuti apange maselo osakanizidwa. Taganizirani zomwe zingatheke: HPBC (Heterojunction with Back Contact), TBC (TOPCon with Back Contact), ndi HBC (Heterojunction Back Contact). Ma hybrid awa ali ngati nyenyezi zazikulu za dziko la dzuwa, kuphatikiza mphamvu za ukadaulo wambiri kuti apititse patsogolo magwiridwe antchito.
Makhalidwe Apadera a Maselo a Dzuwa a BC
1. Kuwala kwa Dzuwa Kosatsekedwa
Popeza mizere yachitsulo ya gridi yasunthidwa kumbuyo, maselo a dzuwa a BC amapereka malo oyera, osasweka omwe amakoka kuwala kwa dzuwa kwambiri ndikusandutsa mphamvu mwachangu kwambiri.
Kugwira Ntchito Moyenera Kwambiri
Kusintha kwa kapangidwe kake kumabweretsa kuchuluka kwa kusintha kwa maselo a dzuwa, zomwe zimapangitsa kuti maselo a dzuwa a BC akhale amphamvu kwambiri m'dziko la mphamvu ya dzuwa.
2. Kukongola Kokongola
Kusowa kwa mizere ya gridi yoyang'ana kutsogolo kumapatsa ma solar panels a BC mawonekedwe okongola komanso ofanana, zomwe zimapangitsa kuti akhale chisankho chokongola pa malo okhala komanso amalonda.
Kuphatikizana kwa Hybrid
Kutha kuphatikiza ukadaulo wa BC ndi ukadaulo wina wotsogola wa dzuwa kumabweretsa maselo osakanizidwa omwe amawonjezera magwiridwe antchito ndi magwiridwe antchito.
3. Kupezeka kwa Msika ndi Ziyembekezo Zabwino
Pakadali pano, ma solar cell a BC ali ngati miyala yamtengo wapatali yobisika pamsika waukulu wa dzuwa, ali ndi gawo la 0.2% poyerekeza ndi 70% ya TOPCon yomwe ndi yayikulu kwambiri. Koma akatswiri opanga ma solar monga LONGi Green Energy akuwona kusintha kwakukulu. LONGi ikuneneratu kuti mkati mwa zaka 5-6 zikubwerazi, ma solar cell a BC adzatchuka kwambiri, zomwe zitha kugwetsa Topcon ngati ukadaulo waukulu wa dzuwa.
4. Tsogolo Ndi Lowala Ndi Ma Cell a BC Solar
Maselo a dzuwa a BC si kusintha pang'onopang'ono; akuyimira kupita patsogolo molimba mtima. Mwa kuchepetsa kutayika kwa mthunzi ndikuwonjezera mphamvu yosinthira, ukadaulo wa BC ukulonjeza kusintha mawonekedwe a mphamvu ya dzuwa. Ngakhale kuti maselo a BC pakadali pano ali pamsika wochepa, magwiridwe awo abwino komanso kukongola kwawo kumawaika pampikisano wamphamvu motsutsana ndi ukadaulo wodziwika bwino monga Perc ndi Topcon.
Mphamvu yeniyeni ya maselo a BC ili mu kusinthasintha kwawo. Mwa kuphatikizana ndi ukadaulo wina, maselo a BC amatha kusintha kukhala magetsi osakanizidwa, kukankhira malire a zomwe maselo a dzuwa angakwanitse. Pamene dziko lapansi likusinthira ku mphamvu zongowonjezwdwanso, maselo a dzuwa a BC amakhala okonzeka kutsogolera mphamvu, kusintha denga kukhala magetsi amphamvu komanso osalala.
Kotero, nthawi ina mukayang'ana dzuwa, ganizirani za matsenga osaoneka a maselo a dzuwa a BC akugwira ntchito mosatopa kuti agwiritse ntchito mphamvu zake. Mu kuwala kulikonse kwa dzuwa muli lonjezo la tsogolo lowala komanso lobiriwira, ndipo ukadaulo wa BC uli pano kuti ukwaniritse lonjezo limenelo.
