Kushandisa Rare-Earth Elements Kukunda Kuganhurirwa kweSolar Cells
Perovskite solar masero ane zvakanakira pane yazvino solar cell tekinoroji. Vane mukana wekuita zvakanyanya, huremu, uye mutengo wakaderera pane zvimwe zvakasiyana. Mune perovskite solar cell, jira re perovskite rakasungirirwa pakati pe electrode yakajeka kumberi uye inoratidzira electrode kumashure kwesero. Electrode transport uye magomba ekutakura akaiswa pakati pecathode uye anode interfaces, iyo inofambisa kuunganidzwa kwechaji pama electrode. Kune zvikamu zvina zveperovskite solar masero akavakirwa pane morphology chimiro uye layer inoteedzana yechaji yekutakura layer: yenguva dzose planar, inverted planar, yenguva dzose mesoporous, uye inverted mesoporous zvimiro. Nekudaro, zvipingamupinyi zvakawanda zviripo neiyo tekinoroji. Chiedza, unyoro, uye okisijeni zvinogona kukonzeresa kudzikisira kwavo, kunyura kwavo kunogona kufananidzwa, uye ivo vanewo nyaya neiyo isiri-radiative charge recombination. Perovskites inogona kusvibiswa nemvura electrolytes, zvichiita kuti kugadzikana nyaya. Kuti vaone mashandisiro avo anoshanda, kuvandudzwa kunofanirwa kuitwa mukushandurwa kwesimba ravo nekugadzikana kwekushanda. Zvisinei, kufambira mberi kwezvino mune teknolojia kwakatungamirira kune perovskite masero ezuva ane 25.5% kunyatsoshanda, izvo zvinoreva kuti havasi kure shure kwemaitiro e-silicon photovoltaic solar cells. Kuti izvi zviitike, zvisingawanzo zvinhu zvepasi zvakaongororwa kuti zvishandiswe mu perovskite solar cells. Ivo vane photophysical zvimiro zvinokunda matambudziko. Kuzvishandisa mu perovskite solar masero zvinozovandudza zvivakwa zvavo, zvichiita kuti zvive nyore kune yakakura-yakakura kuitiswa kwemhinduro dzakachena dzesimba. Karaoke Dailymotion vid Perovskite Solar Cells Kune akawanda anobatsira zvinhu izvo zvisingawanzo zvinhu zvepasi zvine izvo zvinogona kushandiswa kugadzirisa basa reichi chizvarwa chitsva chemasero ezuva. Chekutanga, oxidation uye kudzikisira kugona mune isingawanzo-yepasi ion zvinodzorereka, zvichideredza iyo yakanangwa oxidation uye kudzikisira. Pamusoro pezvo, iyo yakaonda-firimu kuumbwa kunogona kudzorwa nekuwedzera kwezvinhu izvi nekubatanidza iwo ese perovskites uye yekuchaja yekutakura simbi oxides. Uyezve, chimiro chechikamu uye optoelectronic zvivakwa zvinogona kugadziridzwa nekuisa panzvimbo payo mukristaro lattice. Defect passivation inogona kubudirira kubudirira nekudziisa muchinhu chakanangwa kungave kupindirana pamiganho yezviyo kana pamusoro pechinhu. Uyezve, infrared uye ultraviolet mafotoni anogona kushandurwa kuita perovskite-inopindura inooneka mwenje nekuda kwekuvapo kweakawanda anesimba ekuchinja anotenderera mune isingawanzo-yepasi ion. Zvakanakira izvi zvakapetwa kaviri: inodzivirira iyo perovskites kukuvadzwa nehupamhi-yakasimba mwenje uye inowedzera iyo spectral mhinduro renji. Kushandisa zvisingawanzo pasi zvinhu zvinonyanya kunatsiridza kugadzikana uye kugona kwe perovskite solar masero. Kugadzirisa Morphologies yeMafirimu Matete Sezvambotaurwa, zvisingawanzo zvinhu zvepasi zvinogona kugadzirisa morphologies yemafirimu matete anoumbwa nesimbi oxides. Yakanyatsorongedzerwa kuti morphology yepasi pekutakura kutakura kwekutakura inokonzera morphology ye perovskite layer uye kusangana kwayo nechaji chekutakura chekutakura. Semuenzaniso, doping ine isingawanzo-epasi ion inodzivirira kuunganidzwa kweSnO2 nanoparticles iyo inogona kukonzera kukanganisa kwechimiro, uye zvakare kuderedza kuumbwa kwemakristasi makuru eNiOx, kugadzira yunifomu uye compact layer yemakristasi. Saka, akaonda akaturikidzana mafirimu ezvinhu izvi asina kuremara anogona kuwanikwa neisingawanzo-yepasi doping. Uyezve, iyo scaffold layer mu perovskite masero ane mesoporous chimiro anoita basa rakakosha mumatanho ari pakati pe perovskite uye masheji ekutakura ekutakura mumasero ezuva. Iwo nanoparticles mune izvi zvimiro anogona kuratidza morphological hurema uye yakawanda miganhu yezviyo. Izvi zvinotungamira kune yakaipa uye yakakomba isiri-radiative charge recombination. Kuzadza pore inyaya zvakare. Doping ine isingawanzo-epasi ion inogadzirisa kukura kwescaffold uye inoderedza kuremara, kugadzira yakabatana uye yunifomu nanostructures. Nekupa kuvandudzwa kweiyo morphological structure ye perovskite uye masheji ekutakura ekutakura, zvisingawanzo pasi ions zvinogona kuvandudza kushanda kwese uye kugadzikana kweperovskite solar cells, zvichiita kuti zvive zvakakodzera kune zvakakura zvekutengeserana kushandiswa. Kukosha kweperovskite solar masero hakugone kuderedzwa. Ivo vanozopa epamusoro simba rekugadzira simba kune yakaderera zvakanyanya pane yazvino silicon-yakavakirwa solar maseru pamusika. Chidzidzo chacho chakaratidza kuti doping perovskite ine-rare-earth ions inovandudza maitiro ayo, zvichiita kuti kuve nekuvandudzwa kwekushanda uye kugadzikana. Izvi zvinoreva kuti perovskite solar masero ane kuvandudzwa kwekuita inhanho imwe padyo nekuva chokwadi.
