Mukugadzirwa kwemaseru ezuva eperovskite nemidziyo ye optoelectronic nemazvo, kururama kwemaitiro ekuputira kunotarisa zvakananga kushanda kwe photoelectric conversion yezvigadzirwa. Sechinhu chikuru chemidziyo yekuputira, density parameter ye granite (kazhinji 2600-3100kg/m³) haisi chiratidzo chemuviri chete asi chinhu chakakosha chinokanganisa zvakanyanya kugadzikana, kuramba kudedera uye kuvimbika kwenguva refu kwemidziyo. Inotevera iongororo yekubatana kwayo mukati kubva pazvikamu zvina zvikuru.
Kuvakwa kwenheyo yakasimba ine "zero displacement" kwakawanda
Mapendi ePerovskite ane zvinodiwa zvakanyanya kuti pamusoro pe substrate pave pakadzikama (Ra≤0.5μm), uye chero kusuduruka kwehwaro kunogona kukonzera ukobvu hwemapendi husina kuenzana kana zvikanganiso zve pinhole. Granite ine density ye ≥3100kg/m³ inogona kugadzira inertial mass yakasimba zvikuru nekuda kwechimiro chayo chemineral chakabatana mukati. Mune imwe TOPCon perovskite tandem battery production line, mushure mekushandisa high-density granite base, coating thickness deviation ye coating thickness yemidziyo yakaderera kubva ±15nm kusvika ±3nm pasi pemamiriro ekutenderera kwe high-frequency mechanical vibration (50-200Hz), zvichivandudza zvakanyanya kuenderana kwe current-voltage curve yebhatiri.
2. Mugumisiro wakanaka wehukama pakati pekuwanda kwevanhu uye kuderera kwekudengenyeka
Munguva yekuputira, kufamba nekukurumidza kwemusoro wekuputira wakarurama (nekumhanya kwakatsetseka kunodarika 800mm/s) kunogona kukonzera kurira kwemuchina. Zvidzidzo zvinoratidza kuti pakuwedzera kwe10% kwehuwandu hwegranite, kushanda kwekudzikisa kutenderera kunogona kuwedzerwa ne18%. Kana huwandu hwacho hwasvika 3100kg/m³, frequency yahwo yechisikigo inogona kunge yakaderera kusvika 12Hz, zvichidzivirira zvinobudirira huwandu hunonzwa kutenderera (20-50Hz) hwemuchina wekuputira. Kuedza kwechikwata chekutsvagisa cheGerman kwakaratidza kuti hwaro hwegranite hwakanyanya hwakawedzera kufanana kwehukobvu hwefirimu hwe perovskite spin-coating process ne27% uye hwakaderedza mwero wekukanganisa ne40%.
3. Kushanda kwekupisa kwakasimba kwakanyanya
Zvinhu zvePerovskite zvinonzwa zvakanyanya kana tembiricha yachinja. Kuchinja kwe0.1℃ kunogona kukonzera kukanganiswa kwelattice. Nekuda kwekuva pedyo kwenzvimbo yemaatomu mukati, coefficient yekuwedzera kwekupisa kwegranite ine density yakakwira (4-6×10⁻⁶/℃) yakaderera ne30% pane yezvinhu zvemazuva ese. Mukuita kwe annealing (100-150℃), base ine density yakakwira inogona kudzora kushanduka kwekupisa kwezvikamu zvakakosha zvemidziyo mukati me ±0.5μm, ichiva nechokwadi chekuti coating inochengetedza nanoscale flat mushure mekurapwa kwekupisa kwakakwira uye kudzivirira kutsemuka kwe coating kunokonzerwa nekushushikana kwekupisa.
4. Vimbiso yekushanda kwenguva refu "yekudzivirira kuneta"
Midziyo yekufukidza perovskite inoshanda kwemaawa anopfuura gumi nematanhatu pazuva paavhareji, uye hwaro hunofanira kutsungirira kumanikidzwa kwemuchina nguva dzose. Granite ine density ye3100kg/m³ ine simba rekumanikidza re ≥200MPa uye resistance yayo yekupfekwa yakapetwa kashanu pane yesimbi yakajairika. Data chaiyo yekuyera yefekitori yeperovskite module yakagadzirwa nehukuru inoratidza kuti mushure mekushanda kwenguva refu kwemakore matatu, kururama kwekuisa muchina wekufukidza une high-density granite base kwakaderera ne0.8% chete, nepo midziyo ine low-density base yakaderera ne3.2% munguva imwe chete, zvichideredza zvakanyanya mari yekugadzirisa michina uye njodzi yekusashanda.
Mhedziso: Kusarudza vanhu vakawanda zvinoreva kusarudza kushanda zvakanaka
Kubva pakunyatsogadzirwa kwe nanoscale coating kusvika pakushanda kwenguva refu kwakagadzikana kwemitsetse yekugadzira, huwandu hwegranite hwave chinhu chikuru chinokurudzira mashandiro emidziyo yeperovskite coating. Kune makambani ekugadzira anotsvaga kushanda zvakanaka uye mhando, kusarudza mabhesi egranite emhando yepamusoro ane simba re ≥3100kg/m³ (senge zvigadzirwa zvakabvumidzwa neZHHIMG®) hazvingovimbisi chete maitiro aripo asiwo zvinomirira mari yekudyara yekuvandudza kugona mune ramangwana.
