Lub luag haujlwm ntawm Graphite hauv Photovoltaic Devices
Tom ntej no - tiam photovoltaic technologies xav tau cov khoom siv hluav taws xob uas sib txuas cov hluav taws xob hluav taws xob zoo, tshuaj lom neeg ruaj khov, tus nqi qis thiab kev sib raug zoo nrog cov khoom loj -. Graphite thiab lwm cov pa roj carbon -raws li cov ntaub ntawv ua tau raws li kev sib xyaw ua ke hauv ntau hom khoom siv, saum toj no tag nrho hauv cov xim xim -sensitised solar cells (DSSCs) thiab perovskite solar cells, qhov chaw uas lawv ua hauj lwm raws li counter electrodes, rov qab electrodes los yog conductive txheej thiab txo cov dependence ntawm platinum thiab kub.
High Electrical Conductivity thiab Efficiency Charge Transfer
Lub graphite electrode sau cov khoom siv hluav taws xob, txo qis kev ua haujlwm thiab txhim kho kev thauj mus los ntawm cov txheej txheem ntawm cov cuab yeej. Nyob rau hauv ib qho zas xim -sensitised cell lub graphite counter electrode catalyses txo qis tri-iodide ions hauv electrolyte, kaw lub voj voog hloov hluav taws xob kom lub cell tuaj yeem ua haujlwm ntxiv. Nyob rau hauv ib lub cell perovskite ib graphite rov qab electrode rho tawm nqi los ntawm perovskite txheej thiab, vim hais tias nws yog chemically inert rau lub halide chemistry, nws kuj txhim kho stability ntawm lub tiav lawm ntaus ntawv.
Tus nqi tsim thiab kev sib raug zoo nrog Scalable Manufacturing
Platinum thiab kub yog cov khoom siv hluav taws xob cov khoom siv hauv cov xim dye-sensitised hlwb, thiab lawv cov nqi yog ib qho teeb meem rau kev lag luam. Graphite hloov qhov kev suav, thiab nws kuj tseem haum rau txoj kev tso nyiaj uas twb tau siv rau ntawm cov kab module: tshuaj ntsuam luam ntawv, txheej, number case -raws li deposition thiab lamination.
Loj - cheeb tsam photovoltaic modules ua rau ntawm cov txheej txheem luam tawm.
Lub hnub ci hloov tau yooj yim ntawm cov polymer lossis hlau ntawv ci substrates.
Tsawg- nqi hluav taws xob hnub ci tshuab rau kev faib tawm.
Kev lag luam- nplai ntau lawm nrog cov txheej txheem yooj yim, rov ua dua.
Tshuaj thiab Electrochemical Stability
Lub neej ua haujlwm ntev yog qhov tseem ceeb rau lub hnub ci hluav taws xob electrodes. Graphite resists tshuaj degradation thiab tuav nws cov kev ua tau zoo raws li photovoltaic kev ua haujlwm. Hauv dye-sensitised hlwb nws yog sib xws nrog cov iodide thiab tri-iodide electrolyte system thiab qhia zoo catalytic kev ua si rau lub tri-iodide txo cov tshuaj tiv thaiv. Hauv cov khoom siv perovskite, cov pa roj carbon electrodes txwv cov teeb meem cuam tshuam nrog hlau electrode corrosion, noo noo rhiab heev thiab ion tsiv teb tsaws, tag nrho cov uas ua rau lub neej luv ntawm cov hlwb ua rau cov hlau sib txuas.
Daim ntawv thov thoob plaws hnub ci Cell Technologies

Hauv dye-sensitised solar cells cov graphite lossis carbon txheej ua raws li lub txee electrode: nws catalyses cov tshuaj tiv thaiv electrolyte redox, sau electrons thiab hloov platinum, uas txo cov nqi ntawm tes. Nyob rau hauv perovskite hnub ci hlwb graphite yog siv raws li ib tug rov qab electrode uas muaj zoo conductivity, txhim kho tshuaj stability, compatibility nrog tsawg - nqi fabrication thiab ib txoj kev mus rau loj - cheeb tsam modules.
Outlook rau Carbon Electrodes hauv Photovoltaics
Kev lag luam photovoltaic txuas ntxiv mus rau cov khoom siv uas pheej yig dua, yooj yim rau kev tsim khoom, ruaj khov dua hauv kev ua haujlwm thiab zoo dua haum rau ntau lawm. Graphite electrodes ua tau raws li txhua qhov yuav tsum tau ua, uas ua rau lawv muaj kev xaiv zoo rau tus nqi - cov cuab yeej siv tau yooj yim thiab cov khoom tsim tawm tshiab thiab thaj chaw muaj kev loj hlob rau ob lub chaw kuaj mob thiab cov ntawv luam tawm. Cov qib sib txawv, qhov ntau thiab tsawg thiab cov txheej txheem binder yog siv nyob ntawm txoj kev tso nyiaj thiab lub hom phiaj conductivity, yog li kev xaiv electrode feem ntau ua ua ke nrog cov txheej txheem ntaus ntawv.
