I te whanaketanga tonu o te ao o ēnei rā, kei te memeha haere te kaha kore-whakahou, ā, kei te hiahia nui te hapori tangata ki te whakamahi i te kaha whakahou e tohuhia ana e te "hau, te mārama, te wai me te karihi". Ki te whakatauritea ki ētahi atu puna kaha whakahou, kei te tangata te hangarau tino pakari, tino haumaru me te pono mō te whakamahi i te kaha o te rā. I roto i ēnei, kua tino tere te whanaketanga o te umanga pūtau photovoltaic me te silicon teitei-parakore hei papa. I te mutunga o te tau 2023, kua neke atu i te 250 gigawatts te kaha whakauru photovoltaic solar o tōku whenua, ā, kua eke te whakaputanga hiko photovoltaic ki te 266.3 piriona kWh, he pikinga tata ki te 30% ia tau, ā, ko te kaha whakaputanga hiko hou kua tāpirihia ko te 78.42 miriona kirowati, he pikinga 154% ia tau. I te mutunga o Hune, ko te kaha whakauru o te whakaputanga hiko photovoltaic tata ki te 470 miriona kirowati, kua hipa ake i te hiko wai hei puna hiko tuarua nui rawa atu i tōku whenua.
Ahakoa te tere o te whanaketanga o te umanga photovoltaic, kei te tere hoki te whanaketanga o te umanga rauemi hou e tautoko ana i tēnei umanga. Ngā wāhanga Quartz pēnei i tengā oko whakarewa kuata, ngā poti kuata, me ngā pounamu kuata kei roto i ēnei, e whai wāhi nui ana ki te tukanga hanga photovoltaic. Hei tauira, ka whakamahia ngā ipu whakarewa kuata hei pupuri i te silicon rewa i roto i te hanga o ngā tokotoko silicon me ngā ingot silicon; ka whai wāhi ngā poti kuata, ngā ngongo, ngā pounamu, ngā tāke horoi, me ētahi atu ki te horapa, te horoi me ētahi atu hononga tukanga i roto i te hanga o ngā pūtau rā, me ētahi atu, hei whakarite i te parakore me te kounga o ngā rauemi silicon.
Ngā tono matua o ngā wāhanga kuata mō te hanga photovoltaic
I roto i te tukanga hanga o ngā pūtau photovoltaic rā, ka whakatakotoria ngā papa silicon ki runga i tētahi poti papa, ā, ka whakatakotoria te poti ki runga i tētahi tautoko poti papa mō te horapa, te LPCVD me ētahi atu tukanga wera, ko te hoe cantilever silicon carbide te wāhanga uta matua mō te neke i te tautoko poti e kawe ana i ngā papa silicon ki roto, ki waho hoki i te oumu whakamahana. E ai ki te pikitia i raro nei, ka taea e te hoe cantilever silicon carbide te whakarite kia ōrite te porowhita o te papa silicon me te ngongo oumu, kia ōrite ai te horapa me te kore e pāhekoheko. I taua wā anō, kāore he parahanga, kāore hoki e piko i ngā pāmahana teitei, he pai te ātete ki te ru wera me te kaha uta nui, ā, kua whakamahia whānuitia i roto i te mara o ngā pūtau photovoltaic.
He hoahoa kauwhata o ngā wāhanga matua e utaina ana te pākahiko
I roto i te tukanga horapa taunga ngohengohe, ko te poti quartz tuku iho mepoti angiangiMe hono te tautoko i te anga silicon me te tautoko poti quartz ki roto i te ngongo quartz i roto i te oumu horapa. I ia tukanga horapa, ka whakatakotoria te tautoko poti quartz kua whakakiia ki ngā anga silicon ki runga i te hoe karawiti silicon. I muri i te urunga o te hoe karawiti silicon ki roto i te ngongo quartz, ka totohu aunoa te hoe ki raro hei whakatakoto i te tautoko poti quartz me te anga silicon, kātahi ka hoki mārire ki te pūtake. I muri i ia tukanga, me tango te tautoko poti quartz mai i tehoe karawiti silicon. Mā te whakamahi auau pēnei ka pakaru te tautoko poti kuata mō te wā roa. Kia pakaru, kia whati hoki te tautoko poti kuata, ka taka te tautoko poti kuata katoa mai i te hoe waro hiko, kātahi ka pakaru ngā wāhanga kuata, ngā papa hiko me ngā hoe waro hiko i raro. He utu nui te hoe waro hiko, ā, kāore e taea te whakatika. Kia puta he aituā, ka nui ngā mate taonga ka pā mai.
I roto i te tukanga LPCVD, ehara i te mea ko ngā raruraru ahotea wera kua whakahuatia ake nei anake ka puta, engari nā te mea me haere te hau silane i roto i te wafer silicon i roto i te tukanga LPCVD, ka hangaia hoki e te tukanga roa he paninga silicon i runga i te tautoko poti wafer me te poti wafer. Nā te koretake o ngā tauwehenga whānui wera o te silicon me te quartz kua pania, ka pakaru te tautoko poti me te poti, ā, ka tino whakaitihia te roa o te ora. Ko te roa o te ora o ngā poti quartz noa me ngā tautoko poti i roto i te tukanga LPCVD he 2 ki te 3 marama noa iho. Nō reira, he mea tino nui kia whakapai ake i te rauemi tautoko poti kia nui ake ai te kaha me te roa o te ora o te tautoko poti kia kore ai e pāngia e ēnei aituā.
I te poto, i te mea ka piki haere te wā tukatuka me te maha o ngā wā i te wā e hangaia ana ngā pūtau hiko, ka ngāwari ngā poti kuata me ētahi atu wāhanga ki te pakaru, ki te pakaru rānei. Ko te roanga o te ora o ngā poti kuata me ngā ngongo kuata i roto i ngā raina whakaputa matua i Haina i tēnei wā ko te 3-6 marama, ā, me kati tonu kia horoia, kia tiakina, kia whakakapia hoki ngā kawe kuata. Heoi anō, ko te onepu kuata parakore teitei e whakamahia ana hei rauemi mata mō ngā wāhanga kuata kei roto i te āhua iti o te tuku me te tono, ā, kua roa te utu e rere ana i te taumata teitei, e kitea ana kāore e pai ana ki te whakapai ake i te pai o te whakaputa me ngā painga ōhanga.
Ngā uku karawiti silicon"whakaatu mai"
Ināianei, kua hangaia e te tangata tētahi rauemi he pai ake te mahi hei whakakapi i ētahi wāhanga kuata - arā, he uku hikareti waro.
He kaha miihini, he pumau wera, he ātete pāmahana teitei, he ātete waikura, he ātete ru wera me te ātete waikura matū ngā uku silicon carbide, ā, he whānuitia te whakamahinga i roto i ngā mara wera pēnei i te whakarewa, te mīhini, te pūngao hou, me ngā rauemi hanga me ngā matū. He rawaka hoki tōna mahi mō te horapa o ngā pūtau TOPcon i roto i te hanga photovoltaic, te LPCVD (te whakatakoto kohu matū pēhanga iti), te PECVD (te whakatakoto kohu matū plasma) me ētahi atu hononga tukanga wera.
Tautoko poti karawiti silicon LPCVD me te tautoko poti karawiti silicon whakawhanui-boron
Ki te whakaritea ki ngā rauemi kuata tuku iho, he kaha ake ngā tautoko poti, ngā poti, me ngā hua ngongo i hangaia ki ngā rauemi uku silicon carbide, he pai ake te pumau o te wera, kāore he rerekētanga i ngā pāmahana teitei, ā, he roa ake te ora o ngā rauemi kuata e 5 ngā wā, ka taea te whakaiti i te utu whakamahi me te ngaronga pūngao i puta mai i te tiaki me te wā kore mahi. He mārama te painga utu, ā, he whānui te pūtake o ngā rauemi mata.
I roto i ēnei, he iti te pāmahana sintering o te tauhohenga sintered silicon carbide (RBSiC), he iti te utu whakaputa, he nui te whakakīkī rauemi, ā, kāore e tata te whakahekenga o te rōrahi i te wā o te sintering tauhohenga. He tino pai mō te whakarite i ngā wāhanga hanganga rahi me te āhua uaua. Nō reira, he tino pai mō te hanga i ngā hua rahi me te uaua pērā i ngā tautoko poti, ngā poti, ngā hoe cantilever, ngā ngongo oumu, me ētahi atu.
Ngā poti angiangi silicon carbidehe nui hoki ngā tūmanakohanga whanaketanga ā muri ake nei. Ahakoa te tukanga LPCVD, te tukanga whakawhānui boron rānei, he iti noa te roa o te ora o te poti quartz, ā, kāore te tauwehenga whakawhānui wera o te rauemi quartz e ōrite ki te rauemi silicon carbide. Nō reira, he ngāwari te rerekētanga i roto i te tukanga taurite ki te pupuri poti silicon carbide i te pāmahana teitei, ka arahi ki te āhuatanga o te rūrū i te poti, te pakaru rānei o te poti. Ka tangohia e te poti silicon carbide te ara tukanga o te hanga kotahi-wahi me te tukatuka whānui. He teitei ngā whakaritenga mō te āhua me te tūnga, ā, he pai ake te mahi tahi me te pupuri poti silicon carbide. Hei tāpiri, he kaha te silicon carbide, ā, he iti ake te tūponotanga ka pakaru te poti nā te tukinga tangata i te poti quartz.
Waka angiangi silicon carbide
Ko te ngongo oumu te wāhanga matua o te oumu, e whai wāhi ana ki te hiri me te whakawhiti wera ōrite. Ki te whakatauritea ki ngā ngongo oumu kuata, he pai te kawe wera o ngā ngongo oumu silicon carbide, te whakamahana ōrite, me te pumau wera pai, ā, e 5 ngā wā neke atu te roa o te ora i ngā ngongo kuata.
Whakarāpopototanga
I te nuinga o te wā, ahakoa te mahi a te hua, te utu rānei o te whakamahinga, he nui ake ngā painga o ngā rauemi uku silicon carbide i ngā rauemi quartz i roto i ētahi āhuatanga o te mara pūtau solar. Ko te whakamahinga o ngā rauemi uku silicon carbide i roto i te umanga photovoltaic kua tino āwhina i ngā kamupene photovoltaic ki te whakaiti i te utu haumi o ngā rauemi āwhina me te whakapai ake i te kounga hua me te whakataetae. I te heke mai, me te whakamahinga nui o ngā ngongo oumu silicon carbide rahi nui, ngā poti silicon carbide teitei-parakore me ngā tautoko poti me te whakahekenga tonu o ngā utu, ko te whakamahinga o ngā rauemi uku silicon carbide i roto i te mara o ngā pūtau photovoltaic ka noho hei mea matua ki te whakapai ake i te whai huatanga o te hurihanga pūngao mārama me te whakaiti i ngā utu ahumahi i roto i te mara o te whakaputa hiko photovoltaic, ā, ka whai pānga nui ki te whanaketanga o te pūngao hou photovoltaic.
