Lisele tsa photovoltaic li fetola khanya ea letsatsi hore e be motlakase

Photovoltaic (PV) cell, eo hangata e bitsoang solar cell, ke sesebelisoa se sa sebetseng se fetolang khanya ea letsatsi ka ho toba hore e be motlakase. Lisele tse ling tsa PV li ka fetola leseli la maiketsetso hore e be motlakase.

Lifoto li na le matla a letsatsi

Khanya ea letsatsi e entsoe ka li-photon, kapa likaroloana tsa matla a letsatsi. Li-photon tsena li na le mefuta e fapaneng ea matla e lumellanang le maqhubu a fapaneng a maqhubu

Phallo ea motlakase

Ho sisinyeha ha lielektrone, e 'ngoe le e 'ngoe e na le tjhaji e mpe, ho leba bokapeleng ba sele ho baka ho se leka-lekane ha tjhaji ya motlakase pakeng tsa bokapele ba sele le bo ka morao. Ho se leka-lekane hona ho hlahisa matla a motlakase joalo ka liteishene tse mpe le tse ntle tsa betri. Li-conductors tsa motlakase seleng li monya lielektrone. Ha li-conductor li kopantsoe potolohong ea motlakase ho mojaro o ka ntle, joalo ka betri, motlakase o phalla potolohong.

Ho sebetsa hantle ha tsamaiso ea photovoltaic ho fapana le mofuta oa theknoloji ea photovoltaic

Bokhoni boo lisele tsa PV li fetolelang khanya ea letsatsi ho motlakase bo fapana ho ea ka mofuta oa thepa ea semiconductor le theknoloji ea PV cell. Bokhoni ba li-module tsa PV tse fumanehang khoebong bo ne bo le ka tlase ho 10% bohareng ba lilemo tsa bo-1980, bo eketsehile ho ea ho hoo e ka bang 15% ka 2015, 'me hona joale e atamela 20% bakeng sa li-module tsa morao-rao tsa bonono. Lisele tsa liteko tsa PV le lisele tsa PV bakeng sa limmaraka tsa niche, joalo ka li-satellite tsa sebaka, li fihletse ts'ebetso e ka bang 50%.

Mekhoa ea photovoltaic e sebetsa joang

PV cell ke motheo oa mohaho oa tsamaiso ea PV. Lisele tsa motho ka mong li ka fapana ka boholo ho tloha ho lisenthimithara tse ka bang 0.5 ho isa ho tse 4 ka bophara. Leha ho le joalo, sele e le 'ngoe e hlahisa 1 kapa 2 Watts feela, e leng motlakase o lekaneng feela bakeng sa lisebelisoa tse nyenyane, tse kang ho matlafatsa li-calculator kapa lioache tsa letsoho.

Lisele tsa PV li hoketsoe ka motlakase ka har'a mojule oa PV o pakiloeng, o thata-thata boemo ba leholimo kapa phanele. PV modules li fapana ka boholo le ka bongata ba motlakase oo li ka o hlahisang. PV module matla a ho hlahisa motlakase a eketseha ka palo ea lisele tse ka har'a module kapa sebakeng se ka holim'a module. Li-module tsa PV li ka hokahana ka lihlopha ho theha sehlopha sa PV. Sehlopha sa PV se ka etsoa ka li-module tsa PV tse peli kapa tse makholo. Palo ea li-module tsa PV tse hokahantsoeng ka har'a sehlopha sa PV li etsa qeto ea palo eohle ea motlakase oo sehlopha se ka o hlahisang.

Lisele tsa photovoltaic li hlahisa motlakase o tobileng hona joale (DC). Motlakase ona oa DC o ka sebelisoa ho tjhaja libeteri tseo le tsona li sebelisang motlakase o sebetsang ka kotloloho. Hoo e ka bang motlakase oohle o fanoa e le alternating current (AC) litsamaisong tsa phetiso le kabo ea motlakase. Lisebelisoa tse bitsoang

Lisele tsa PV le li-module li tla hlahisa palo e kholo ea motlakase ha li shebile letsatsi ka kotloloho. Li-module tsa PV le li-arrays li ka sebelisa lisebelisoa tsa ho latela tse tsamaisang li-modules hore li lule li shebane le letsatsi, empa mekhoa ena e theko e boima. Litsamaiso tse ngata tsa PV li na le li-module sebakeng se tsitsitseng le li-module tse shebileng ka boroa ka ho toba (karolong e ka leboea ea lefatše - ka ho toba leboea karolong e ka boroa ea lefatše) le ka lehlakoreng le ntlafatsang ts'ebetso ea 'mele le moruo ea tsamaiso.

Solar photovoltaic cell li hlophisitsoe ka liphanele (modules), le diphanele ka hlophisoa ka lihlopha tsa boholo bo fapaneng ho hlahisa palo e nyane ho isa ho e kholo ea motlakase, joalo ka ho matlafatsa lipompo tsa metsi bakeng sa metsi a mehlape, bakeng sa ho fana ka motlakase malapeng, kapa bakeng sa ts'ebeliso- ho hlahisa motlakase.
