Kushanda zvakanaka kwemasero ezuva kunodzikira kana maerekitironi nemaburi maviri akabatanazve asati ashandiswa zvinobudirira. Kana semiconductor ikatora chiedza pahurefu hwakakodzera, maerekitironi nemaburi maviri anogadzirwa. Pasi pekuvhenekerwa, huwandu hwemutakuri muchinhu hunopfuura kukosha kwahwo kwechiyero. Kana chiedza chabviswa, huwandu hwemutakuri hunodzokera kuchimiro chahwo chechiyero nenzira inowanzonzi recombination. Pazasi pane nzira dzakasiyana dze recombination:
1. Kubatanidzwazve kweMwaranzi
Kudzokororwa kwechiedza nemwaranzi kunopesana nemaitiro ekunyudzwa kwechiedza, apo maerekitironi anoshanduka kubva pakuva nesimba rakawanda kuenda kukuva nesimba rakaderera, zvichiburitsa simba rakawandisa sechiedza. Rudzi urwu rwekudzokororwa kwechiedza rwakakosha muma semiconductor lasers nema light-emitting diodes (LEDs) asi haruna simba mu silicon solar cells.
2. Kubatanidzazve Auger
Kubatanidzwa kweAuger inzira yekudzoreredza ionisheni yeinjini. Kana maerekitironi negomba zvikabatana, simba rakawandisa rinoendeswa kune rimwe elekitironi pachinzvimbo chekusunungurwa sechiedza. Electron yakashongedzwa inobva yadzoreredza mamiriro ayo ekutanga, ichiburitsa maphononi (simba remagetsi). Kubatanidzwa kweAuger kunonyanya kuoneka muzvinhu zvakaputirwa zvakanyanya, kunyanya kana huwandu hwetsvina huchidarika 10¹⁷ cm⁻³, zvichiita kuti ive nzira huru yekubatanidza muzviitiko zvakadaro.
3. Kubatanidzwazve Kunobatsira Musungo
Kusachena uye zvikanganiso zviri muma semiconductors zvinogadzira mwero wesimba unobvumirwa mukati me bandgap yakarambidzwa. Aya mazinga esimba re defect anorerutsa maitiro e recombination ane matanho maviri: electron inotanga yasununguka kubva pa conduction band kuenda pa defect level yozoenda ku valence band, kwainobatanazve neburi. Maitiro aya anoshanda zvikuru mukusimudzira recombination uye anogona kukanganisa zvakanyanya mashandiro e solar cells.
4. Kubatanidzwazve kwePamusoro
Pamusoro pe semiconductor panogona kuonekwa senzvimbo ine zvikanganiso zvakawanda nekuda kwekugumira kwechimiro chekristaro. Zvikanganiso izvi pamusoro zvinogadzira mamiriro akawanda esimba mukati me bandgap inorambidzwa, uko kubatanidzwazve kunogona kuitika zviri nyore. Kubatanidzwazve pamusoro chinhu chakakosha nekuti chimiro chekristaro pamusoro hachina kurongeka zvakanyanya, zvichiita kuti kubatanidzwazve kuve nyore kuitika munzvimbo idzi.
Mhedziso
Mumasero ezuva anoshanda, nzira idzi dzekubatanidza dzinobatsira mukurasikirwa kwekushanda kwese. Basa revagadziri vemasero nderekuderedza kurasikirwa uku kuti vawedzere kushanda zvakanaka. Maitiro ega ega ekubatanidza anounza matambudziko akasiyana, uye kukunda izvi kuburikidza nekusarudza zvinhu, kupfava pamusoro, uye mazinga ekushandisa zvinodhaka zvakakosha pakuvandudza mashandiro emasero ezuva. Pamusoro pezvo, magadzirirwo akasiyana anosiyanisa masero ezuva akasiyana-siyana ekutengeserana ari mumusika, zvichikanganisa kushanda kwawo uye kugona kwawo kushandiswa.
