Kwiminyaka yakutshanje, ngenxa yokwanda kwemfuno yamandla avuselelekayo kwihlabathi liphela, itekhnoloji yokuvelisa amandla elanga i-photovoltaic iphuhlile ngokukhawuleza. Kubasebenzisi, akukho mahluko mkhulu phakathi kweeseli ze-silicon ze-monocrystalline kunye neeseli ze-silicon ze-polycrystalline, kwaye ubomi bazo kunye nokuzinza kwazo zombini zilungile.
**I-silicon e-monocrystalline: ukusebenza kakuhle kodwa ixabiso liphezulu
Iiphaneli zelanga ze-silicon e-monocrystalline zaziwa ngokusebenza kakuhle kokuguqula, ubumsulwa bezinto ezibonakalayo, ulwakhiwo olupheleleyo lwekristale, kwaye zinokuguqula amandla elanga abe ngamandla ombane ngempumelelo. Nangona kunjalo, inkqubo yokuvelisa i-silicon e-monocrystalline iyinkimbinkimbi kwaye iindleko ziphezulu, nto leyo eye yaba sisizathu sokuba iifektri ezininzi zingayisebenzisi i-silicon e-monocrystalline njengeephaneli zelanga ngobuninzi.
**I-polycrystalline silicon: ingabizi kakhulu kodwa ayisebenzi kakuhle kangako
Ukusebenza kakuhle kokuguqulwa kweepaneli zelanga ze-polycrystalline silicon kuphantsi kancinci kune-monocrystalline silicon, kodwa iindleko zayo zokuvelisa ziphantsi kwaye ukusebenza kakuhle kweendleko kuphezulu. Izixhobo ze-polycrystalline silicon zenziwe ngeekristale ezincinci ezininzi, inkqubo yokuvelisa ilula, kwaye imveliso enkulu inokufezekiswa, ngoko ke zithatha isabelo esikhulu kwimarike. Ke ngoko, iifektri ezininzi ezincinci ziya kukhetha i-polycrystalline silicon njengezinto zeepaneli zelanga ukuze zonge iindleko ezingaphezulu. Kodwa umgangatho kunye nokuqhuba oku kuya kuncipha.
Ngoko ke, xa ukhetha iimodyuli ze-photovoltaic, sicebisa ukuba ukhethe iimodyuli ze-crystal silicon photovoltaic ezivuthiweyo ngokweemeko zokwenyani. Asiboni mahluko mkhulu ekuveliseni umbane kwiinkqubo zokuvelisa umbane ze-photovoltaic zasekhaya. Indawo yokusetyenziswa kweekristale ezingatshatanga iya kuba phezulu, kwaye izinga lokusetyenziswa kwendawo yeekristale ezingatshatanga liya kuba ngcono. Ke ngoko, emva kokuqwalaselwa ngokubanzi, iimveliso zethu zamandla elanga ngokubanzi zisebenzisa i-silicon e-monocrystalline njengemveliso ephambili.
Ezo zizibane zelanga zeLiper zisebenzisa i-silicon yekristale enye.
