Endabirwamu eziriko ebifaananyi (textured glass) zikola zitya mu BIPV?

Abanoonyereza okuva mu Poland beekenneenyezza engeri endabirwamu eziriko obutonde gye zikozesebwamu ng’ekibikka eky’omu maaso ku... ebikozesebwa mu kuzimba ebizimbe ebiyitibwa photovoltaic bikosa enkola y’emirimu. Baakizuula nti amaanyi agafuluma gali wansi ebitundu 5% bw’ogeraageranya n’ebitundu ebisinziira ku ndabirwamu ez’ennono, nga ebipimo by’okutunula bituuka ku bitundu 88% mu nsengekera y’ekitangaala ekirabika.

Bannasayansi okuva mu John Paul II Catholic University of Lublin, Poland, beekenneenyezza ebipimo by’amaaso n’amasannyalaze eby’endabirwamu eziriko obutonde mu nkola z’amasannyalaze agayitibwa building-integrated photovoltaic (BIPV). Baakizuula nti ekika ky’endabirwamu kino kisobola okukosa ennyo obutonde bw’amasannyalaze g’ekitangaala n’okwongera ku kutunula kw’ekitangaala. 'Mu bifo ebiteekebwa mu bibuga, ekintu ekikulu ye muwendo gw'okutunula ogwa wansi , ogukendeeza ku kutunula kw'ekitangaala ekiyinza okuziba amaaso g'abavuzi,' Paweł Wanicki, omuwandiisi omukulu mu kunoonyereza kuno bwe yategeezezza. 'Nga BIPV yeeyongera okwettanirwa, okugaziya okuteekebwa kwayo ku.' façades, ebisenge by'ebizimbe n'ebika by'endabirwamu eby'enjawulo , ensonga zaayo ez'obulungi bifuuse ekimu ku bikulu ebipima.'

Endabirwamu eziriko ebifaananyi (textured glass) zikolebwa nga bafumbisa ebipande by’endabirwamu okubigonza, olwo ne babibumba nga bayita mu biwujjo ebiyooleddwa. Mu kunoonyereza kwabwe, abanoonyereza bano bakozesezza ebika bibiri eby’endabirwamu eziriko obutonde ezitundibwa. Sampuli esooka erina enkula y’okungulu ng’ekyukakyuka mu buwanvu bwa micrometers 45, ate sampuli eyookubiri egwa mu bbanga lya micrometers 10. Sampuli 1 erimu omusono ogwa bulijjo nga gulina obuwanvu obw’engeri ya mayiromita 400, so nga Sampuli 2 erina omusono ogutali gwa bulijjo nga guliko ebifaananyi okuva ku mayiromita 50 okutuuka ku milimita ezisukka mu emu.

Okutwalira awamu, modulo ssatu zazimbibwa —emu nga erina sampuli 1, endala nga erina sampuli 2, ate esembayo nga erina endabirwamu entangaavu eya reference. Mu mbeera zonna, ekipande kya laminate kyateekebwa wakati w’endabirwamu n’akasenge, era amaanyi agaweebwa ekipapula gapimibwa nga 2.89 W. Ekisenge ekitaliiko kintu kyonna kyapimibwa okuba n’ensonga y’okujjuza eya 71%, vvulovumenti ya open circuit ya 0.699 V, ne current ya short circuit eya 5.83 A.

'Okusinziira ku kubalirira, emiwendo gy'okunyiga amaanyi g'enjuba obutereevu mu sampuli ejuliziddwa giri wansi kumpi emirundi 13 n'emirundi 5 okusinga egya sampuli 1 ne 2,' abanoonyereza bwe baategeezezza. Ku sampuli zombi eziriko obutonde, obutambuzi mu kitundu ekiriraanye infrared (NIR) buba wansi nnyo okusinga obw’endabirwamu ey’okujuliza. Ekirala, ku sampuli erimu enkola ya bulijjo ey’okungulu (Sampuli 1), obutambuzi mu kitundu kya infrared (IR) buba wansi katono bw’ogeraageranya ne sampuli etali ya bulijjo (Sampuli 2). Okutunula okupimiddwa mu kitundu ekirabika (VIS) kuli wansi nnyo: emirundi 8.5 wansi ku sampuli 1 ate emirundi 1.6 wansi ku sampuli 2. '

Ku ky’okukola kw’amasannyalaze, ekisenge ekijuliziddwa kyapima amaanyi agasinga obunene aga 2.86 W; sampuli 1 yalina amaanyi ga 2.79 W, ate sampuli 2 yalina amaanyi ga 2.74 W. Ensonga y’okujjuza, vvulovumenti ya open circuit, ne current ya short circuit ya modulo ya reference byali 72.4%, 0.73 V, ne 5.425 A. Sampuli 1 yalina vvulovumenti ya 72.9%, 0.727 V, ne 5.27 A, ate sampuli 2 yalina vvulovumenti ya 73.2%, 0.728 V, ne 5.143 A.

Okwekenenya kwalaga nti amaanyi agava mu modulo ezikozesa endabirwamu eziriko obutonde (textured glass) gaali wansi ebitundu 5% ate nga n’ebipimo by’okutunula (reflection parameters) byali waggulu okutuuka ku bitundu 88% mu kitundu kya VIS bw’ogeraageranya ne modulo ezisinziira ku ndabirwamu eza bulijjo.

'Okuva emisinde gya infrared bwe girina ebikosa ebiwerako ku butoffaali bwa silicon photovoltaic, omuli okunyiga amaanyi okutono, ebikosa ebbugumu ebivaako okukendeeza ku bulungibwansi, obuzibu bw'ebintu, n'okufiirwa kw'amaaso olw'okuddamu okugatta abasitula - okukozesa endabirwamu eziriko obutonde mu modulo z'ekitangaala kivaamu amagoba,' abasomesa bwe baamaliriza. Okugatta ku ekyo, okumala ebbanga eddene okukwatibwa emisinde gya infrared kyanguya okuvunda kw’ebintu, bwe kityo ne kikosa obutebenkevu n’obulamu bwa modulo za photovoltaic.

Ebizuuliddwa byabwe byafulumiziddwa mu lupapula lwa 'Textured Glass in Architectural Photovoltaic Applications,' olwafulumiziddwa mu Clean Engineering and Technology. Ng’oggyeeko yunivasite ya John Paul II Catholic University e Lublin, Kwanicki era akwatagana n’ekitongole kya Poland ekigaba amasannyalaze g’ekitangaala ekya ML Systems.

Mu kukozesa pulojekiti za BIPV , naddala ezo ezisangibwa mu bibuga, abakola dizayini z’okuzimba nabo beeraliikirivu nnyo ku kizibu ky’okulaga ekitangaala eky’ebizimbisibwa ebikozesa ekitangaala. Ku pulojekiti zino eza BIPV ezirina ebisaanyizo ebikakali ku kutunula ekitangaala, kungulu kw’endabirwamu ekola amasannyalaze kuyinza okufuulibwa omuzira okutuuka ku nkola y’okutunula ekitangaala eya wansi.
