Musiyano pakati pe monocrystalline uye polycrystalline solar panels

Solar masero ndiwo semiconductor zvishandiso zvinoshandura zvakananga mwaranzi yezuva kuita simba remagetsi zvichibva pane photovoltaic mhedzisiro yemasemiconductors.Ikozvino masero ezuva anotengeswa anonyanya kusanganisira anotevera marudzi: monocrystalline silicon solar masero, polycrystalline silicon solar masero, amorphous silicon solar masero, uye parizvino cadmium telluride masero, copper indium selenide masero, nano-titanium oxide sensitized masero, polycrystalline silicon Thin-firimu solar masero. uye organic solar masero, etc. Crystalline silicon (monocrystalline, polycrystalline) masero ezuva anoda yakakwirira-kuchena silicon raw materials, kazhinji inoda kuchena kweinenge %, kureva, yakawanda ye2 maatomu ekusvibiswa anobvumirwa kuvapo mu 10 mamiriyoni esilicon. maatomu.Iyo silicon zvinhu inogadzirwa nesilicon dioxide (SiO2, inozivikanwawo sejecha) seyakabikwa, inogona kunyungudutswa uye tsvina inobviswa kuti iwane yakakora silicon.Kubva pasilicon dioxide kusvika kumasero ezuva, inosanganisira maitiro akawanda ekugadzira uye maitiro, ayo anowanzo kukamurwa kuita: silicon dioxide-> metallurgical-grade silicon->high-purity trichlorosilane->high-purity polysilicon-> monocrystalline silicon rod kana Polycrystalline silicon. ingot 1 > silicon wafer 1 > solar cell.

Monocrystalline silicon solar masero anonyanya kugadzirwa nesilicone monocrystalline.Kuenzaniswa nemamwe marudzi emasero ezuva, monocrystalline silicon masero ane yakanyanya kutendeuka inoshanda.Mumazuva ekutanga, monocrystalline silicon solar masero akatora yakawanda yemugove wemusika, uye mushure me1998, vakadzokera kune polycrystalline silicon ndokutora nzvimbo yechipiri mumugove wemusika.Nekuda kwekushomeka kwepolysilicon mbishi zvinhu mumakore achangopfuura, mushure me2004, chikamu chemusika chemonocrystalline silicon chakawedzera zvishoma, uye ikozvino mazhinji emabhatiri anoonekwa pamusika ari monocrystalline silicon.Iyo silicon crystal yemonocrystalline silicon solar masero akakwana kwazvo, uye ayo optical, magetsi uye emuchina zvimiro zvakafanana zvakanyanya.Muvara wemasero unonyanya kutema kana rima, iyo inonyanya kukodzera kucheka muzvidimbu zviduku kuita zvigadzirwa zviduku zvevatengi.Shanduko Yekubudirira Inowanikwa muLabhoritari yeMonocrystalline Silicon Masero

Zviri %.Iko kushandiswa kwekushandura kwekutengesa kwakajairika ndeye 10% -18%.Nekuda kwekugadzirwa kwemonocrystalline silicon solar masero, kazhinji masemi-apedzwa silicon ingots ari cylindrical, uye obva aenda kuburikidza nekucheka-> kuchenesa-> diffusion junction-> kubviswa kwemashure emagetsi-> kugadzira maelectrodes-> kukorodza periphery- > kuderedzwa kwe evaporation.Reflective firimu uye mamwe maindasitiri cores anogadzirwa kuita zvigadzirwa zvakapedzwa.Kazhinji, makona mana emonocrystalline silicon solar masero akatenderedzwa.Ukobvu hwemonocrystalline silicon solar masero kazhinji 200uM-350uM gobvu.Iyo yazvino yekugadzira maitiro ndeyekukudziridza kune yakanyanya-yakaonda uye yakanyanya-kugona.Vagadziri vemagetsi ezuva reGerman vakasimbisa kuti 40uM gobvu monocrystalline silicon inogona kuwana 20% shanduko inoshanda.Mukugadzirwa kwepolycrystalline silicon solar masero, iyo yakakwirira-kuchena silicon seyakasvibira haina kunatswa kuita makristasi imwe chete, asi inonyungudutswa uye inokandwa mumativi esilicon ingots, yozogadziriswa kuita zvimedu zvitete uye zvakafanana kugadzirisa senge crystal silicon imwe.Polycrystalline silicon iri nyore kuziva kubva kumusoro kwayo.Iyo silicon wafer inoumbwa nenhamba huru yecrystalline matunhu ehukuru hwakasiyana (iyo yepamusoro ndeye crystalline).

Iro boka rezviyo rakatariswa riri nyore kuvhiringidza kutendeuka kwephotoelectric pane yezviyo interface, saka iyo yekutendeuka inoshanda yepolysilicon yakaderera.Panguva imwecheteyo, kuwirirana kwe optical, magetsi uye mechanical properties ye polysilicon haina kunaka seyoyo monocrystalline silicon solar cells.Kunyanya kushanda kwepolycrystalline silicon solar cell laboratory i%, uye iyo inotengeswa inowanzonzi 10% -16%.Iyo polycrystalline silicon solar cell chikamu chekwere, chine chiyero chepamusoro chekuzadza paunenge uchigadzira solar module, uye zvigadzirwa zvine kunaka.Ukobvu hwepolycrystalline silicon solar masero anowanzo kuita 220uM-300uM gobvu, uye vamwe vagadziri vakagadzira maseru ezuva ane ukobvu hwe180uM, uye vari kusimukira kuhutete kuchengetedza zvinhu zvinodhura zvesilicon.Polycrystalline wafers ndeyekurudyi-angled masikweya kana rectangles, uye makona mana eimwe wafers akakomberedzwa pedyo nedenderedzwa.

Iyo ine gomba rakaita semari pakati pechidimbu ikiristaro imwe chete, inogona kuoneka pakungotarisa.
