Mkpụrụ ndụ anyanwụ ụdị isi nke 1

E mepụtara mkpụrụ ndụ anyanwụ ruo ọgbọ nke atọ, nke ọgbọ mbụ bụ monocrystalline silicon solar cell, ọgbọ nke abụọ bụ silicon amorphous na polycrystalline silicon solar cell, na ọgbọ nke atọ bụ ọla kọpa-steel-gallium-selenide (CIGS) dị ka onye nnọchianya nke ihe nkiri na-emepụta ihe na-emepụta ihe na-egbuke egbuke.
Dịka nkwadebe nke batrị na-eji ihe dị iche iche, enwere ike kewaa mkpụrụ ndụ anyanwụ n'ime ụdị ndị a.

Silicon anyanwụ cell na-ekewa n'ime monocrystalline silicon anyanwụ cell, polycrystalline silicon mkpa-film anyanwụ cell na amorphous silicon mkpa-film anyanwụ cell nke ụdị atọ.
Monocrystalline silicon cell cell anyanwụ nwere arụmọrụ ntụgharị kachasị elu yana teknụzụ kachasị tozuru oke. Ntughari kachasị elu na ụlọ nyocha bụ 23% ọnụ ọgụgụ, na arụmọrụ na mmepụta bụ 15%, nke ka na-achịkwa na nnukwu ngwa ngwa na mmepụta mmepụta ihe. Otú ọ dị, n'ihi ọnụ ahịa dị elu nke silicon monocrystalline, ọ na-esiri ike ibelata ọnụ ahịa ya nke ọma, iji chekwaa ihe ndị dị na silicon, mmepe nke ihe nkiri silicon dị iche iche na-emepụta ihe na-emepụta ihe nkiri sịlịkọn amorphous dị ka ihe ọzọ na-abụghị monocrystalline silicon anyanwụ cell.
Polycrystalline silicon thin-film anyanwụ mkpụrụ ndụ na monocrystalline silicon anyanwụ cell, na-eri dị ala, mgbe arụmọrụ dị elu karịa amorphous silicon mkpa-film anyanwụ cell, kasị elu ntughari arụmọrụ nke ya laabu bụ 18%, ntughari arụmọrụ nke ulo oru-ọnụ ọgụgụ mmepụta bụ 10%. Ya mere, polycrystalline silicon mkpa film anyanwụ cell ga-achị n'oge na-adịghị anya anyanwụ cell ahịa.
Amorphous silicon thin film sel anyanwụ dị ọnụ ala, ịdị arọ dị arọ, arụmọrụ ntụgharị dị elu, dị mfe imepụta ọtụtụ, nwere ikike dị ukwuu. Otú ọ dị, na-egbochi ya site na mmepụta fotoelectric arụmọrụ nke ihe onwunwe ya na-ebelata, nkwụsi ike adịghị elu, na-emetụta ngwa ngwa ya ozugbo. Ọ bụrụ na anyị nwere ike n'ihu dozie nsogbu nkwụsi ike ma melite ọnụego mgbanwe, mgbe ahụ, amorphous silicon anyanwụ cell bụ ihe ịrụ ụka adịghị ya na isi mmepe nke sel anyanwụ nke ngwaahịa!
(2) Multi-ngwakọta mkpa film anyanwụ cell
Ngwakọta ihe nkiri dị n'ụba dị iche iche maka nnu inorganic, gụnyere ogige gallium arsenide, cadmium sulfide, cadmium sulfide na ọla kọpa a tụrụ mkpọrọ selenium mkpa ihe nkiri batrị.
Cadmium sulfide, cadmium telluride polycrystalline mkpa-film anyanwụ cell arụmọrụ dị elu karịa ndị na-abụghị pin silicon mkpa-film anyanwụ cell, ndị na-eri bụ ala karịa monocrystalline silicon anyanwụ cell, na dịkwa mfe na nnukwu-ọnụ ọgụgụ mmepụta, ma n'ihi na cadmium nwere a elu toxicity, ga-eme ka njọ mmetọ nke gburugburu ebe obibi, nke kacha mma n'ime sel nke silicon n'ihi ya, ọ bụghị ihe ọzọ na-akpata.
