Masero ePhotovoltaic (PV) anowanzo gadzirwa nezvinhu zvakaita sesilicon uye ane maelectrode akanaka neasina kunaka. Kana akavhenekerwa nezuva, simba rephotovoltaic rinoitika, richichinja simba rechiedza kuita simba remagetsi nenzira yemagetsi akananga (DC). Magetsi aya anogona kuchengetwa mumabhatiri kana kushandurwa kuita alternating current (AC) kuburikidza ne inverter kuti agutse zvinodiwa zvakasiyana-siyana zvesimba. Masero ePV anowanzo batanidzwa mu series kana parallel to form modules, ayo anobva aunganidzwa kuita arrays kuti pave nesimba guru rinobuda.
1. Masero eAluminium Back Surface Field (BSF)
Maumbirwo uye Nheyo
Masero eBSF imhando yakajairika yemasero ezuva anoshandisa aruminiyamu seelectrode yekumashure. Izvi zvinoumba munda wemagetsi wekumashure unobatsira kufambisa maerekitironi kuenda kuelectrode yekumashure, zvichiwedzera kushanda zvakanaka kwekushandura simba. Maitiro ekugadzira anosanganisira kuisa phosphorus pamusoro pesilicon kugadzira nzvimbo yerudzi rweN, kuisa firimu kana coating kugadzira nzvimbo yerudzi rweP kumberi, uye kugadzira pn junction. Pakupedzisira, magrid esimbi anowedzerwa kuti aunganidze magetsi.
Nhoroondo Yebudiriro
Masero eBSF akatanga kurongwa muna 1973, ndiwo aive magadzirirwo ekutanga emasero esilicon akagadzirwa nekristaro. Pakazosvika 2016, aive neanopfuura 90% yemugove wemusika.
Zvakanakira
Masero eBSF anozivikanwa nekureruka kwawo, kushanda zvakanaka pamari, uye tekinoroji yakakura.
2. Masero ePERC
Kutumidza Mavambo
PERC inomiririra Passivated Emitter uye Rear Cell.
Maitiro uye Mashandiro
Kuvakira pamasero eBSF echinyakare, tekinoroji yePERC inowedzera matanho maviri akakosha: kupfapfaidza pamusoro pekumashure uye kuvhura nelaser, zvichiwedzera kushanda zvakanaka. Maitiro ekugadzira anosanganisira kuchenesa nekugadzira machira ewafer, kupararira kwepn junctions, kushandisa laser yekusarudza emitters, kupfapfaidza kumashure, kuboora nelaser, kudhinda pascreen, sintering, uye kuyedza.
Zvakanakira
Masero ePERC ane chimiro chiri nyore, maitiro mapfupi ekugadzira, uye kushanda kwemidziyo kwakakwirira.
3. Masero eHeterojunction (HJT)
Maumbirwo
Masero eHJT masero ezuva akabatana anosanganisa crystalline silicon substrates nemafirimu esilicon amorphous. Anosanganisira ma silicon layers emukati amorphous pa heterojunction interface kuti apfavise nzvimbo dzepamberi nedzekumashure. Chimiro chakafanana chinosanganisira substrate yesilicon yemhando yeN, silicon layer yePi amorphous padivi rinotarisa chiedza, silicon layer ye iN amorphous kumashure, uye ma electrodes uye busbars akajeka kumativi ese. Aya masero maviri.
Zvakanakira
Masero eHJT ane mashandiro akanaka, kuora kwakaderera, tembiricha yakaderera, kuenzana kwakanyanya, maitiro akareruka, uye kukodzera mawafer akatetepa.
4. Masero eTOPCon
Nheyo yeUnyanzvi
Masero eTOPCon (Tunnel Oxide Passivated Contact) akavakirwa pamutemo wekusarudza wekutakura. Ane silicon oxide layer yakatetepa zvikuru uye silicon layer yakasanganiswa kumashure, zvichigadzira chimiro chekubatana chisina kubatwa. Izvi zvinoderedza kusanganiswa kwekubatana kwepamusoro nesimbi, zvichigadzira mukana wakakura wekuvandudza kushanda zvakanaka kwemasero eN-PERT.
Maitiro Ekuita
Masero eTOPCon anoshandisa substrates dzesilicon dzerudzi rweN uye anoda shanduko shoma pamitsetse yekugadzira yemhando yeP iripo, senge kuwedzera boron diffusion uye thin-film deposition equipment. Anobvisa kudiwa kwekuvhura nekurongedza kumashure, zvichiita kuti kugadzirwa kuve nyore uye kuwedzera kuenderana nemaitiro ePERC neN-PERT cell.
Zvakanakira
Masero eTOPCon haaratidzi kuora kwakanyanya, kusimba kwakanyanya, uye tembiricha yakaderera, zvichipa mashandiro akanaka kwazvo muzvishandiso zvemagetsi ezuva.
5. Masero eIBC
Maumbirwo uye Nheyo
Masero eInterdigitated Back Contact (IBC) anotamisa mitsetse yese yegrid yeelectrode yekumberi kuenda kumashure, achironga ma pn junctions uye simbi dzinobatana nenzira yakasiyana. Izvi zvinoderedza mumvuri uye zvinowedzera kupinza chiedza. Pasina simbi dzinobatana nemberi, masero eIBC anopa nzvimbo yakakura yekushandura photon.
Kubatanidzwa kweTekinoroji
Masero eIBC anogona kubatana nemamwe matekinoroji akadai sePERC, TOPCon, HJT, uye perovskite, zvichigadzira masero emhando yepamusoro akaita se "TBC" (TOPCon-IBC) uye "HBC" (HJT-IBC).
Kukwanisa Kushandisa
Nekugadzirwa kwavo kwakanaka, masero eIBC akakodzera kugadzirwa kwemagetsi emagetsi (BIPV) uye ane mikana yakakura yekutengeserana.
Mhedziso
Rudzi rumwe nerumwe rwesero rePV rune zvakanakira zvakasiyana uye runoita basa guru mukusimudzira matekinoroji esimba rezuva. Kuburikidza nekuvandudza zvinhu zvitsva, matekinoroji aya ari kutungamira kukura nekushandurwa kweindasitiri yemagetsi ezuva.
