Maselo a dzuwa ndi zida za semiconductor zomwe zimatembenuza mwachindunji ma radiation a dzuwa kukhala mphamvu zamagetsi pogwiritsa ntchito mphamvu ya photovoltaic ya semiconductors.Tsopano ma cell a solar omwe amagulitsidwa amaphatikizanso mitundu iyi: ma cell a solar a monocrystalline silicon, ma cell a solar a polycrystalline silicon, ma cell a amorphous silicon solar cell, komanso ma cell a cadmium telluride, ma cell a copper indium selenide, cell cell sensitized nano-titanium oxide, polycrystalline silicon Thin-film solar cell. ndi organic maselo dzuwa, etc. Crystalline pakachitsulo (monocrystalline, polycrystalline) maselo dzuwa amafuna mkulu-chiyero silikoni zopangira, zambiri amafuna chiyero cha osachepera%, ndiko kuti, munthu pazipita 2 zonyansa maatomu amaloledwa kukhalapo pa 10 miliyoni pakachitsulo. ma atomu.Zinthu za silicon zimapangidwa ndi silicon dioxide (SiO2, yomwe imadziwikanso kuti mchenga) ngati zopangira, zomwe zimatha kusungunuka ndikuchotsa zonyansa kuti zipeze silicon yolimba.Kuchokera ku silicon dioxide kupita ku ma cell a solar, kumaphatikizapo njira zingapo zopangira ndi njira, zomwe nthawi zambiri zimagawidwa kukhala: silicon dioxide->metallurgical-grade silicon->high-purity trichlorosilane->high-purity polysilicon->monocrystalline silicon rod kapena Polycrystalline silicon ingot 1 > silicon wafer 1 > cell solar.
Maselo a dzuwa a monocrystalline silicon amapangidwa makamaka ndi silicon ya monocrystalline.Poyerekeza ndi mitundu ina ya ma cell a solar, maselo a silicon monocrystalline ali ndi mphamvu zosintha kwambiri.M'masiku oyambilira, ma cell a solar a monocrystalline silicon adatenga gawo lalikulu pamsika, ndipo pambuyo pa 1998, adabwerera ku polycrystalline silicon ndikutenga malo achiwiri pamsika.Chifukwa cha kuchepa kwa zida za polysilicon m'zaka zaposachedwa, pambuyo pa 2004, gawo la msika la silicon ya monocrystalline lakula pang'ono, ndipo tsopano mabatire ambiri omwe amawoneka pamsika ndi silicon ya monocrystalline.Silicon crystal ya monocrystalline silicon solar cell ndi yangwiro kwambiri, ndipo mawonekedwe ake a kuwala, magetsi ndi makina amafanana kwambiri.Mtundu wa maselo nthawi zambiri wakuda kapena wakuda, womwe umakhala woyenera kwambiri kudula mu zidutswa zing'onozing'ono kuti apange mankhwala ang'onoang'ono ogula.Kusintha Mwachangu Kukwaniritsidwa mu Laboratory of Monocrystalline Silicon Cells
Ndi %.Kuthekera kwa kutembenuka kwa malonda wamba ndi 10% -18%.Chifukwa cha kupanga ma cell a solar a monocrystalline silicon, nthawi zambiri ma semi-anamalizidwa a silicon ingots ndi cylindrical, ndiyeno amadutsa slicing->kuyeretsa->kuphatikizana->kuchotsa ma elekitirodi ammbuyo->kupanga maelekitirodi->kuwononga periphery-> > kuchepetsa evaporation.Mafilimu owonetsera ndi ma cores ena ogulitsa amapangidwa kukhala zinthu zomalizidwa.Nthawi zambiri, ngodya zinayi za maselo a dzuwa a monocrystalline silicon ndi ozungulira.Makulidwe a ma cell a solar a monocrystalline silicon nthawi zambiri amakhala 200uM-350uM wandiweyani.Kapangidwe kamakono kakukulirakulira kukhala woonda kwambiri komanso kuchita bwino kwambiri.Opanga ma cell a solar aku Germany atsimikizira kuti 40uM wandiweyani monocrystalline silikoni amatha kukwaniritsa 20% kutembenuka mtima.Popanga ma cell a solar a polycrystalline silicon, silicon yoyera kwambiri ngati zopangira sizimayeretsedwa kukhala makhiristo amodzi, koma amasungunuka ndikuponyedwa muzitsulo za silicon, kenako ndikusinthidwa kukhala magawo oonda komanso kukonza kofananako ngati silicon imodzi ya crystal.Silicon ya polycrystalline ndiyosavuta kuzindikira kuchokera pamwamba pake.Chophimba cha silicon chimapangidwa ndi zigawo zambiri za crystalline za kukula kwake (pamwamba ndi crystalline).
Gulu la tirigu lolunjika ndilosavuta kusokoneza kutembenuka kwa photoelectric pamawonekedwe ambewu, kotero kuti kusinthika kwa polysilicon kumakhala kochepa.Panthawi imodzimodziyo, kusinthasintha kwa mawonekedwe a kuwala, magetsi ndi makina a polysilicon si abwino ngati a monocrystalline silicon solar cell.Kuchita bwino kwambiri kwa labotale ya solar cell ya polycrystalline silicon ndi %, ndipo yogulitsa nthawi zambiri imakhala 10% -16%.Selo ya solar ya polycrystalline silicon ndi gawo lalikulu, lomwe limadzaza kwambiri popanga ma module a solar, ndipo zinthu zake ndi zokongola.Makulidwe a ma cell a solar a polycrystalline silicon nthawi zambiri amakhala 220uM-300uM wandiweyani, ndipo opanga ena apanga ma cell a solar okhala ndi makulidwe a 180uM, ndipo akupanga kuonda kuti apulumutse zida za silicon zodula.Zophika za Polycrystalline ndi mabwalo am'mbali kapena makona anayi, ndipo ngodya zinayi za zowotcha zing'onozing'ono zimapindika pafupi ndi bwalo.
Yemwe ali ndi dzenje lopangidwa ndi ndalama pakati pa chidutswacho ndi galasi limodzi, lomwe limatha kuwoneka pang'onopang'ono.
