Ahupūngao Practical: tukungaaho

No mea pehea tawhiti te tangata toharite i roto i to ratou oraraa ia rā kotahi traversed e te marautanga kura, he mea he, kahore-kahore he a ka meinga e pā ana ki mahara koe. Ko tenei te mea e tupu, no te tae mai te reira ki te āhuatanga o te tukungaaho.

whakamāramatanga

riro Photoeffect ahupūngao tukanga tīaroaro irahiko i roto i te ngota, rāpoi, matū, e whakatika e tupu ka whai wāhi ki te marama. He tukungaaho - he tukanga i roto i nei e te patototanga i roto i te marama irahiko ki kaha taua e haere ki tua atu i te rohe o waho o te rauemi.

Hītori me Practice

Hoki te wā tuatahi i runga i tenei meka mīharo kite ahupūngao i Germany, Genrih Gerts i tawhiti i te 1887. i haere tonu te whakatuwheratanga o te ako hoa Hertz, ahupūngao Russian Stoletov. He poto, whakawhanakehia Einstein te ariā o te awenga whakaahua-hiko i runga i nga whakaaro o te ahupūngao aronui. Mai nui hohonu tukungaaho ako me pūkenga, ka tono te matauranga riro i roto i ki tonu i roto i te hoahoa me te hanga o ngā pūrere photovoltaic hāngai i runga i. Ki te tangohia e tatou i te tauira tino taketake, tenei aunoa kuwaha mo te karati, rere i runga i ngā pūtau solar.

Tikanga o tenei momo mahi i runga i te pūngao hiko. Heoi, pūtau solar e whakamahi photoeffect waho anake, taui pūngao hua i roto i radiation ki hiko kore rawa. Na reira, ki te whakamahi i ratou rite puna o hiko he kahore tikanga motuhake, e kore e taea te mea e pā ana ki aunoatanga. Ko reira te awhina o kurupae marama puta ki iahiko hāngai i roto i ngā tikanga mana aunoa.

Kahore faarahiraa, e taea te tohe i te reira e ko te kitea o te awenga whakaahua-hiko he kaupapa pono hou i roto i te ahupūngao. Tenei ko te nui tino o ona mau hopearaa:

• i mua i te pūtaiao heheu mai te āhua ngaro o te marama, te kurupae marama;
• pikitia i te puku i "e korero ana" i whakaaro ara o te reo, a ka kua hanga ano hoki te meka o te whakawhitinga o te whakapakoko neke whakawhetai taea ki te awenga whakaahua-hiko;
• hanga i runga i te pūtake o ngā pūrere hiko taua mihini me "mihini atamai" e, homai nga tawhā o te wahi ngā e hanga kahore wawaotanga tangata;
• he plurality o tikanga rerekē e hāngai ana i runga i te aunoatanga photoelectron.

Ko te kupu, ko te tino whakamahi i o te awenga whakaahua-hiko, a meinga ana e ia he pakaruhanga i roto i te hangarau hou.

whakarōpū o ngā pūtau solar

E wehea pānga Photo ki te maha ngā momo rite ki o ratou āhuatanga me mahi.

1. Te pānga waho pūaho ā (i roto i te kupu atu - photoelectron paheke). E huaina ana te irahiko e kua tukuna ki waho te taonga ina puta reira irahiko aho. Na he nāianei hiko, i whai ahua ai ratou ina he nekehanga maau i roto i te mara hiko waho, i huaina photocurrent.
2. awenga whakaahua-hiko ā-, awe te rauemi photoconductive. Puta reira ka e tūariarihia irahiko i runga i Semiconductors me insulators i runga i te āhua pūngao o te whakawhāititanga me te rānei - he totoka wai ranei. puta Tuhinga tītohunga raro i te mana o te marama. Reira ka faarahi te kawenga hiko o te taonga, i.e., huri i te reira i roto i te pānga o te photoconductivity.
3. Piha awenga whakaahua-hiko - te whakawhitinga o ngā irahiko aho i ratou tinana i roto i te tahi atu totoka (Semiconductors) wai (kawehiko) ranei.

awenga whakaahua-hiko waho ko te pūtake o te mahi o photocells mārua hou. E hangaia ana ratou i roto i te pounamu whakaata i roto i nei te wāhanga pani te mata i roto ki te kahu angiangi o te waipara konganuku. whakarato te matotoru paparanga iti te putanga iti mahi. haere matapihi Puata roto te pūrama me te kei roto te reira i te pitoake i te puka o koropiko waea irahiko aho pono kōpae ranei. Ki te te pitoake hono ki te pou pai o te pūhiko, kati reira te ara iahiko, haere ki runga ki o nāianei hiko. ie Ka taea e korehau pūtau solar tahuri i runga i runga i te tānga ranei.

Mā te whakakotahi i ngā pūtau solar me tānga, ka taea e koe te hanga i tētahi momo o "te kitenga" mihini, hei tauira, te mīhini i roto i te arā raro.

Na, he mea whakatakotoria i roto i te pūtake o te maha tukanga ahumahi, i matua ki te mahi angitu o te aunoatanga ahumahi te awenga whakaahua-hiko waho rite te āhuatanga nui tinana.
