Izesekeli ze-graphite zezithando zomlilo zekristalu eyodwa embonini ye-photovoltaic zidlala indima ebalulekile ekukhiqizeni amaseli elanga. Zithinta ngokuqondile ukusebenza kahle kokukhiqiza kanye nekhwalithi yamangqamuzana elanga ngokunikeza indawo ezinzile yokushisa nokusekela ukukhula kwamakristalu e-silicon eyodwa. Ngakho-ke, ucwaningo nokuthuthukiswa kanye nokusha kwenziwa ngokuqhubekayo ukuze kuthuthukiswe ukusebenza, ukuqina nokuguquguquka kwezesekeli ze-graphite ukuze kuhlangatshezwane nezidingo zomkhakha we-photovoltaic oguqukayo.
Isingeniso:
1. Ukukhethwa kwezinto ezibonakalayo: Izesekeli ze-graphite zensimu eshisayo yesithando somlilo se-crystal eyodwa embonini ye-photovoltaic ngokuvamile zisebenzisa izinto ze-graphite ezihlanzekile. Lezi zesekeli ze-graphite zidinga ukuba nokuhlanzeka okuphezulu, okuqukethwe kokungcola okuphansi kanye ne-conductivity enhle kakhulu yokushisa ukuze kuqinisekiswe ukuzinza kwensimu eshisayo nokuqina ezindaweni ezishisayo.
2. I-Thermal field design: Idizayini yezesekeli ze-graphite zensimu eshisayo yesithando somlilo se-crystal eyodwa idinga ukucabangela ukufana nokuzinza kwensimu eshisayo. Ukuma nokwakheka kwezesekeli ze-graphite kudlala indima ebalulekile ekuqhubeni nasekusabalaliseni insimu eshisayo ukuze kuqinisekiswe ukuthi i-silicon eyodwa crystal ishisa ngokulinganayo esithandweni futhi ithola ukusatshalaliswa kokushisa okuhambisanayo.
3. I-Thermal conductivity: Izesekeli ze-graphite zensimu eshisayo yesithando somlilo se-crystal eyodwa embonini ye-photovoltaic idinga ukuba ne-conductivity enhle ye-thermal ukuze inikeze ukuqhutshwa kokushisa okuphumelelayo nokusabalalisa ukushisa okufanayo. Lokhu kusiza ukuqinisekisa ukuthi ikristalu ye-silicon eyodwa ishisiswe ngokulinganayo kuyo yonke inqubo yokukhula esithandweni futhi yehlise umthelela wama-gradients okushisa kwikhwalithi yekristalu.
4. Ukumelana nokushisa okuphezulu: Njengoba izinga lokushisa lokukhula esithandweni somlilo esisodwa se-crystal ngokuvamile liphakeme, izesekeli ze-graphite zensimu eshisayo yesithando somlilo se-crystal embonini ye-photovoltaic kudingeka zibe nokumelana okuhle kokushisa okuphezulu. Kufanele bakwazi ukugcina ukuqina kwesakhiwo namandla emishini endaweni yokushisa ephezulu ukuze kuqinisekiswe ukusebenza okuzinzile kwesikhathi eside.
5. Ukumelana nokugqwala: Izesekeli ze-graphite zensimu eshisayo yesithando somlilo se-crystal eyodwa embonini ye-photovoltaic nazo zidinga ukumelana nokugqwala okuhle ukuze zibhekane nokusabela kwamakhemikhali okungenzeka lapho kuhlangene nezinto ze-silicon namanye amakhemikhali. Lokhu kusiza ukugcina ukuzinza nokuphila kwezesekeli ze-graphite.
