Endabirwamu ekola amasannyalaze ga cadmium telluride kye ki?

Green and low-carbon kiruubirirwa kikulu eky'enkulaakulana mu kiseera ky'ensi yange ' s ' 14th Five-Year Plan ' , Okukola amasannyalaze aga Photovoltaic ge maanyi amakulu okutuukiriza ekiruubirirwa kino. Mu nkola y’okukulaakulana okw’amangu okw’amakolero g’amasannyalaze g’ekitangaala, Ng’oggyeeko obutoffaali bwa silikoni obwa kirisitaalo obusikiriza ennyo, bbaatule za firimu ennyimpi ezikozesa cadmium telluride nga layeri y’okunyiga nazo zisikiriza amakolero okufaayo. 

Cadmium telluride power generation glass is a low-carbon, green, energy-saving, energy-creating, environmentally friendly and safe new energy and new material, Kiba kizimbe kya kiragala era ensibuko y'amasoboza amayonjo, Kirina engeri eza bulijjo ez'endabirwamu y'ebizimbe, Ennungi era ennungi, emisono egy'enjawulo, Okukola amasannyalaze amatono, Okuwa ebizimbe amaanyi, Okufuula ensi ennungi ennyo, Ye okulonda okuyamba okutuuka ku biruubirirwa by'ebizimbe 'entikko ya kaboni' ne 'obutabeera na kaboni'.

Cadmium telluride (CdTe) is an important II-VI compound semiconductor material , Enkula ye obutundutundu bwa kirisitaalo obuddugavu oba butto, Ekifo ekisaanuuka kituuka ku 1092 °C , Obuzito bwa molekyu obw’enjawulo 240, Ensengekera ya kirisitaalo ya kika kya sphalerite, Erina ensengekera y’amasoboza ag’enkyukakyuka obutereevu. Lattice constant yaayo eri 0.6481nm, Obugazi bwa bandgap buli 1.45eV, Entambula y’obusannyalazo mu bbugumu ly’ekisenge eri 1050 c ㎡ /(Vs), Entambula y’ekituli mu bbugumu ly’ekisenge yali 80 c ㎡ /(Vs).

Amasoboza g’ekiyungo ky’ekiyungo ky’eddagala ekya cadmium telluride gali waggulu nga 5.7eV, Y’emu ku mbeera z’obutonde ezisinga okutebenkera ez’okusengejja eddagala lya elementi cadmium mu butonde. N’olwekyo, cadmium telluride enywevu mu kemiko ku bbugumu erya bulijjo, era tesaanuuka mu mazzi, asidi enafu, Tekirina bulabe nnyo mu kiseera ky’okukola n’okukozesa mu makolero.

Kinajjukirwa nti, Okuddamu okw’embala y’obutoffaali bw’enjuba obwa cadmium telluride kukwatagana nnyo n’ensaasaanya y’embala y’enjuba ey’oku ttaka, Obusobozi bwennyini obw’okukola amasannyalaze bwa maanyi.

Cadmium telluride erina omulimu ogutebenkedde, High light energy absorption coefficient, N-ekika oba P-ekika semiconductor ebintu bisobola okufunibwa nga doping obucaafu obw'enjawulo, Kiyinza okukozesebwa mu kukola nuclear radiation detectors (okukozesebwa mu by'obujjanjabi), infrared electro-optical modulators, infrared detectors, infrared lenses n'amadirisa n'ebyuma ebirala. Mu kifo ky’obusannyalazo bw’ekitangaala, Cadmium telluride etwalibwa ng’ekintu ekikulu ekisookerwako mu kutegeka obutoffaali bwa firimu ennyimpi ey’enjuba obunene. Firimu ya cadmium telluride erimu obuwanvu bwa 2 μ m zokka (micron), Omuwendo gw’okunyiga mu maaso gusukka 90% wansi w’embeera za AM1.5 eza mutindo, Obulung’amu bw’okukyusa mu ndowooza buli waggulu nga 33%, N’olwekyo, amaanyi g’enjuba gafuuse ekifo ekinene ennyo eky’okukozesa cadmium telluride. Mu budde obwabulijjo, amakolero g’amasannyalaze g’ekitangaala geetaaga okukozesa cadmium telluride n’obulongoofu bwa 5N.

Bw’ogeraageranya n’obutoffaali bw’enjuba obulala, Ensengekera y’obutoffaali bw’enjuba obwa firimu ennyimpi eya cadmium telluride nnyangu nnyo; Okutwaliza awamu, Enzimba y’ennono erimu emiryango etaano, Kwe kugamba, endabirwamu substrate, transparent conductive oxide layer (TCO layer), cadmium sulfide (CdS) window layer, cadmium telluride (CdTe) absorption layer, back contact layer ne back electrode, Nga bwe kiragibwa mu kifaananyi wansi.

Nga enkola y’enkola y’omunda ey’okukuuma amaanyi mu kuzimba egenda etereera mpolampola,  Essira gavumenti ly’eteeka ku kuzimba okukozesa amaanyi amalungi lyeyongedde nnyo. Singa ebiruubirirwa bya kaboni bbiri biba bigenda kutuukirizibwa, Tekyawukana ku kkubo ddene ery’okuzimba amasannyalaze agava mu kitangaala (BIPV).

2020, Minisitule y’amayumba n’okuzimba mu China ne minisitule n’obukiiko obulala musanvu bafulumizza enteekateeka z’ebikolwa ezikwata ku bizimbe ebirabika obulungi, Enteekateeka eno egenderera okukola ebitundu 70% ku bizimbe ebipya ebirabika obulungi mu 2022, Yeetaagibwa okulungamya pulojekiti za gavumenti ez’okusiga ensimbi okukulembera mu kukozesa ebikozesebwa mu kuzimba ebirabika obulungi. Cadmium telluride amasannyalaze okukola endabirwamu ebizimbisibwa okutegekebwa okuyita mu cadmium telluride thin film bbaatule tekinologiya, Ye mulembe omupya ogw'ebizimbe ebirabika obulungi.

Bw’ogeraageranya n’ebitundu bya silikoni ebya kirisitaalo,  modulo za firimu ennyimpi eza Cadmium telluride zirina engeri z’omugerageranyo gw’okunyiga ogw’amaanyi, ekikolwa ky’ekifo ekibuguma ekitono, ekikolwa ekirungi eky’ekitangaala ekitono, okulabika obulungi okw’amaanyi, n’okulongoosa okw’amaanyi, 

Kiyinza okukozesebwa mu ngeri ekyukakyuka ku bizimbe eby’enjawulo nga obusolya bw’ebizimbe ne bbugwe wa kateni,Okwongera ekifo ekirungi eky’okukola amasannyalaze nga tukozesa ennene ennyo ku ngulu w’ekizimbe, Okutuukiriza ebyetaago by’okukola amasannyalaze mu bizimbe eby’enkoona nnyingi, Mu nkomerero okukendeeza ku kaboni afuluma mu bizimbe okuva mu nsibuko. Nga evugirwa enkola ennungi, Okwetaaga kwa cadmium telluride thin film photovoltaic modules kujja kwongera okugaziwa mu biseera eby’omu maaso.
