Libaka tsa mabenkele

Matla a letsatsi a nkehang habobebe a entsoe ka likarolo tse tharo: liphanele tsa letsatsi, libeteri tse khethehileng tsa polokelo le lisebelisoa tse tloaelehileng.Tse peli tsa pele ke linotlolo tse amang boleng le ts'ebetso ea lihlahisoa tsa matla, 'me li lokela ho nkoa ka mokhoa oa ho reka.

Liphanele tsa Solar tse menahang

Ho na le mefuta e meraro ea liphanele tsa letsatsi 'marakeng, ho kenyelletsa liphanele tsa letsatsi tsa monocrystalline silicon, liphanele tsa letsatsi tsa polycrystalline silicon, le liphanele tsa letsatsi tsa amorphous silicon.

Lisele tsa letsatsi tsa Monocrystalline silicon ke lisele tse sebelisoang ka ho fetesisa tsa semiconductor bakeng sa ho hlahisa matla a letsatsi.Ts'ebetso ea eona ea tlhahiso e phethetsoe, ka botsitso bo phahameng le sekhahla sa phetoho ea photoelectric.Ka bobeli Shenzhou 7 le Chang'e 1 tse phatlalalitsoeng ke naha ea heso li sebelisa lisele tsa letsatsi tsa monocrystalline silicon, 'me sekhahla sa phetoho se ka fihla ho 40%.Leha ho le joalo, ka lebaka la litšenyehelo tse phahameng, sekhahla sa phetoho ea lisele tsa letsatsi tsa monocrystalline silicon 'marakeng se pakeng tsa 15% le 18%.

Litsenyehelo tsa lisele tsa letsatsi tsa polycrystalline silicon li tlase ho feta tsa lisele tsa letsatsi tsa monocrystalline, 'me photosensitivity e molemo, e ka khonang ho ela hloko khanya ea letsatsi le khanya ea incandescent.Empa sekhahla sa phetoho ea photoelectric ke 11% -13% feela.Ka nts'etsopele ea thekenoloji, ts'ebetso e boetse e ntlafala, empa katleho e ntse e le tlaase ho feta ea monocrystalline silicon.

Sekhahla sa ho sokoloha ha lisele tsa letsatsi tsa amorphous silicon ke tse tlaase ka ho fetisisa, boemo ba machaba bo tsoetseng pele bo ka bang 10% feela, ha boemo ba malapeng bo le pakeng tsa 6% le 8%, 'me ha bo tsitsitse,' me tekanyo ea ho sokoloha hangata e theoha haholo.Ka hona, lisele tsa letsatsi tsa amorphous silicon li sebelisoa haholo mehloling e fokolang ea motlakase, joalo ka li-calculator tsa elektroniki tsa letsatsi, lioache tsa elektroniki joalo-joalo.Le hoja theko e le tlase, tekanyo ea theko / tshebetso ha e phahame.

Ka kakaretso, ha u khetha motlakase oa letsatsi o nkehang, silicon ea monocrystalline le silicon ea polycrystalline e ntse e le tsona tse ka sehloohong.Ho molemo hore u se ke ua khetha silicon ea amorphous ka lebaka la theko e tlaase.

Betri e khethehileng ea ho mena

Libetri tse khethehileng tsa polokelo bakeng sa matla a letsatsi a nkehang 'marakeng li ka aroloa ka libeteri tsa lithium le libeteri tsa nickel-metal hydride ho latela lisebelisoa.

Libetri tsa lithium li ka tjhaja ka nako efe kapa efe mme ha li na matla a ho hopola.Libetri tsa lithium-ion tsa metsi ke libeteri tsa lithium tse sebelisoang hangata mehalang ea khale kapa lik'hamera tsa dijithale.Ka lehlakoreng le leng, libeteri tsa elektroniki tsa polymer lithium li na le melemo e mengata.Li na le melemo ea ho fokotsa, sebaka se sa tsitsang le sebopeho se ikemetseng, 'me se ke ke sa baka mathata a tšireletso a kang ho lutla ha mokelikeli le ho phatloha ha mollo.Ka hona, ho ka sebelisoa libeteri tsa aluminium-plastiki.Filimi e kopantsoeng e etsa hore betri e be teng, ka hona e eketsa matla a khethehileng a betri eohle.Ha litšenyehelo li ntse li fokotseha butle-butle, libeteri tsa lithium-ion tsa polymer li tla nka sebaka sa libeteri tsa lithium-ion tse tloaelehileng.

Bothata ba libeteri tsa nickel-metal hydride ke hore ho tjhaja le ho lahla ho na le phello ea mohopolo, katleho e batla e le tlase, 'me motlakase oa sele e 'ngoe le e' ngoe ea betri o nyane ho feta oa libeteri tsa lithium-ion, tseo hangata li sa sebelisoeng ke letsatsi le nkehang. mehloli ea matla.

Ho feta moo, libeteri tse nkehang habobebe tsa matla a letsatsi li tla ba le ts'ebetso ea ts'ireletso ea overcharge, overvoltage le ts'ireletso e fetelletseng.Ka mor'a hore betri e tjhajoe ka ho feletseng, e tla koala ka boeona 'me e se ke ea hlola e tjhaja,' me e tla khaola motlakase ka boeona ho sireletsa betri le thepa ea motlakase ha e lokolloa ho isa tekanyong e itseng.
