Chithunzi cha The Principle of Solar Panel
Mphamvu yadzuwa ndiyo gwero labwino koposa lamphamvu kwa anthu, ndipo mikhalidwe yake yosatha ndi yongowonjezedwanso imatsimikizira kuti idzakhala gwero lotsika mtengo kwambiri ndi lothandiza kwambiri kwa anthu. Ma solar ndi mphamvu zoyera popanda kuwononga chilengedwe. Dayang Optoelectronics yakula mwachangu m'zaka zaposachedwa, ndi gawo lofufuza lamphamvu kwambiri, komanso ndi imodzi mwama projekiti apamwamba kwambiri.
Njira yopangira ma solar solar makamaka imachokera ku zida za semiconductor, ndipo mfundo yake yogwirira ntchito ndikugwiritsa ntchito zida za Photoelectric kuti zitenge mphamvu zowunikira pambuyo pa kutembenuka kwa photoelectric, malinga ndi zida zosiyanasiyana zomwe zimagwiritsidwa ntchito, zitha kugawidwa kukhala: ma cell a silicon opangidwa ndi dzuwa ndi woonda. -ma cell a solar filimu, lero makamaka kuti alankhule nanu za mapanelo a dzuwa opangidwa ndi silicon.
Choyamba, silicon solar panels
Mfundo yogwiritsira ntchito ma cell a silicon solar cell ndi chithunzi chojambula Mfundo yopangira mphamvu zama cell a solar makamaka mawonekedwe azithunzi za semiconductors, ndipo kapangidwe kake ka semiconductors ndi motere:
Mlandu wabwino umayimira atomu ya silicon, ndipo mtengo woyipa umayimira ma elekitironi anayi ozungulira atomu ya silicon. Pamene kristalo wa silicon wosakanikirana ndi zonyansa zina, monga boron, phosphorous, ndi zina zotero, boron ikawonjezeredwa, padzakhala dzenje mu kristalo wa silicon, ndipo mapangidwe ake angatanthauze chithunzi chotsatirachi:
Mlandu wabwino umayimira atomu ya silicon, ndipo mtengo woyipa umayimira ma elekitironi anayi ozungulira atomu ya silicon. Chikaso chimasonyeza kuphatikizidwa kwa atomu ya boroni, chifukwa pali ma elekitironi 3 okha kuzungulira atomu ya boroni, kotero idzatulutsa dzenje la buluu lomwe likuwonetsedwa mu chithunzicho, lomwe limakhala losakhazikika kwambiri chifukwa palibe ma elekitironi, ndipo n'zosavuta kuyamwa ma electron ndi kusokoneza. , kupanga semiconductor ya mtundu wa P (zabwino). Mofananamo, pamene maatomu a phosphorous aphatikizidwa, chifukwa maatomu a phosphorous ali ndi ma elekitironi asanu, elekitironi imodzi imakhala yogwira ntchito kwambiri, kupanga ma semiconductors amtundu wa N (negative). Achikasu ndi ma nuclei a phosphorous, ndipo ofiira ndi ma elekitironi owonjezera. Monga momwe chithunzi chili pansipa.
Ma semiconductors amtundu wa P ali ndi mabowo ambiri, pamene ma semiconductors a N-mtundu ali ndi ma electron ambiri, kotero kuti pamene P-mtundu wa P ndi N-mtundu wa semiconductors akuphatikizidwa, kusiyana kwa mphamvu ya magetsi kudzapangidwa pamtunda wolumikizana, womwe ndi mgwirizano wa PN.
Pamene P-mtundu ndi N-mtundu wa semiconductors akuphatikizidwa, wosanjikiza wapadera woonda kwambiri amapangidwa m'chigawo chapakati cha ma semiconductors awiri), ndipo mbali ya P-mtundu wa mawonekedwe imakhala yolakwika ndipo mbali ya N-mtundu imayimbidwa bwino. Izi ndichifukwa choti ma semiconductors amtundu wa P ali ndi mabowo angapo, ndipo ma semiconductors amtundu wa N ali ndi ma elekitironi ambiri aulere, ndipo pali kusiyana kwa ndende. Ma electron m'chigawo cha N amafalikira kudera la P, ndipo mabowo a m'chigawo cha P amafalikira kudera la N, kupanga "munda wamagetsi wamkati" wochokera ku N kupita ku P, motero amalepheretsa kufalikira. Pambuyo pofika pamlingo wofanana, wosanjikiza wapadera woterewu umapangidwa kuti apange kusiyana komwe kungakhalepo, komwe ndi mphambano ya PN.
Chipindacho chikawonekera, mabowo a semiconductor yamtundu wa N mu mphambano ya PN amasunthira kudera la mtundu wa P, ndipo ma elekitironi omwe ali m'chigawo cha P-mtundu amapita kudera la mtundu wa N, zomwe zimapangitsa kuti pakhale mphamvu yapano. chigawo chamtundu wa N kupita kudera lamtundu wa P. Ndiye kusiyana komwe kungakhalepo kumapangidwa mumgwirizano wa PN, womwe umapanga magetsi.
