Itekhnoloji ye-Thin-film photovoltaic (PV) ivele njengesebe elibalulekileyo lokuvelisa amandla elanga, inika iingenelo ezikhethekileyo ezifana nokuguquguquka, uyilo olukhaphukhaphu, kunye nokusebenza kakuhle kweendleko. Utshintsho lwayo ukusuka kuvavanyo lwakuqala ukuya ekusetyenzisweni ngokubanzi lubonisa indlela yokuvelisa izinto ezintsha okuqhubekayo kunye nokuziqhelanisa ukuhlangabezana neemfuno ezikhulayo zamandla avuselelekayo.
Imvelaphi ye-PV yefilimu ethe tyaba iqala ngeminyaka yoo-1970, iqhutywa kukufuna ezinye iindlela ezingasetyenziswayo kwiiseli zelanga ze-silicon zemveli. Uphuhliso lwakuqala, kuquka iseli ye-silicon yefilimu ethe tyaba yokuqala eyaphuhliswa yiXerox ngo-1972, lwabeka isiseko sodidi olutsha lwetekhnoloji yelanga. Ngeminyaka yoo-1980, i-silicon engaguqukiyo (a-Si) yaba yinto yokwenyani yorhwebo, ngenxa yeendleko zayo eziphantsi zemveliso. Nangona ukusebenza kwayo kuncinci, i-PV yefilimu ethe tyaba yafumana imakethi yayo yokuqala ngenxa yokufikeleleka kwayo kunye nokukwazi kwayo ukukhulisa.
Iminyaka yoo-1990 yaphawula ixesha elibalulekileyo kwitekhnoloji yefilimu encinci njengoko abaphandi bazisa izixhobo eziphambili ezifana ne-copper indium gallium selenide (CIGS) kunye ne-cadmium telluride (CdTe). Ezi zinto zintsha zonyusa kakhulu ukusebenza kakuhle kwaye zavula iingcango kwizicelo ezintsha. I-CIGS yagqama ngamazinga ayo aphezulu okuguqulwa kunye nokuguquguquka, okwenza ukuba ifaneleke kwiindlela ezahlukeneyo zokusetyenziswa, ngelixa i-CdTe yafumana udumo ngenxa yokusebenzisa kwayo iindleko kunye nokukhula kwayo, ngakumbi kwiifama ezinkulu zelanga. Ezi nkqubela zaqinisa i-PV yefilimu encinci njengendlela yokukhuphisana kunobuchwepheshe belanga obuqhelekileyo.
Kwiminyaka yoo-2000, i-PV yefilimu encinci yangena kwinqanaba lokukhula ngokukhawuleza. Iindlela zokuvelisa eziphuculweyo kunye nokuphuculwa kwezinto zokwenza izinto zehlise iindleko, nto leyo eyabangela imfuno yehlabathi. Abadlali abaphambili kushishino bandise imveliso, kwaye i-PV yefilimu encinci yafumana ukuthandwa kwiiprojekthi ezinkulu zelanga. Ukuziqhelanisa nobuchwepheshe kwenza ukuba ibe lukhetho olukhethwayo kwiintlobo ngeentlobo zezicelo, ukusuka eluphahleni ukuya kwiifama zelanga.
Namhlanje, i-PV yefilimu encinci iyaqhubeka nokukhula, ibonakaliswa ziindlela ezintsha ezahlukeneyo kunye neendlela zokusetyenziswa ezikhethekileyo. I-silicon engafaniyo ihlala ixabisekile kwiimeko eziphantsi kokukhanya kunye neemarike ze-niche, ezifana ne-Building-Integrated Photovoltaics (BIPV) kunye nezixhobo eziphathwayo. Okwangoku, i-CIGS igqwesile kwizicelo ezisebenzayo eziphezulu ezifuna ukuguquguquka, kwaye i-CdTe ilawula ukufakwa okukhulu ngenxa yokufikeleleka kwayo. Olu phuculo luye lwabeka i-PV yefilimu encinci njengomnikeli onamandla kwimbonakalo yamandla avuselelekayo.
Ikamva le-PV yefilimu ethe tyaba lixhomekeke ekufezekiseni ukusebenza kakuhle okuphezulu, ukunciphisa iindleko zemveliso, kunye nokuphucula uzinzo lokusingqongileyo. Uphando oluqhubekayo lujonge ukuphucula izixhobo ezifana ne-CIGS kunye ne-CdTe, ngelixa uphuhliso kwiinkqubo zokuvelisa ezinobuhlobo nokusingqongileyo lujolise ekunciphiseni impembelelo yokusingqongileyo. Le mizamo ilungele ukomeleza ukhuphiswano lwe-PV yefilimu ethe tyaba kunye nokwandisa ukuthandwa kwayo kwiimarike.
Iimpawu ezikhethekileyo zeThin-film PV ziye zavumela ukuhlanganiswa kwayo kwiindlela ezahlukeneyo zokusebenza, ukusuka kwiinkqubo zokuhlala kunye nophahla lwemizi-mveliso ukuya kwiiprojekthi ze-elektroniki eziphathwayo kunye ne-agrivoltaic. Ukuguquguquka kwayo kuvumela ukubandakanywa okungenamthungo kwimizobo yezakhiwo, kudibanisa ubuhle kunye nokuveliswa kwamandla. Kwezolimo, i-thin-film PV ixhasa iinkqubo ezisetyenziswa kabini, inika amandla ngelixa iphucula iimeko zokusingqongileyo.
Njengoko utshintsho lwamandla lwehlabathi lukhawuleza, i-thin-film PV imiselwe ukudlala indima ebaluleke ngakumbi. Uphuhliso lwayo lugxininisa ukuzinikela ekuveliseni izinto ezintsha, ukunciphisa iindleko, kunye nokugcinwa kwendalo. Ngokujongana nemingeni kunye nokwamkela amathuba, itekhnoloji ye-thin-film PV iya kuqhubeka negalelo kwikamva lamandla elizinzileyo, ihambelana neenjongo zehlabathi zokwamkelwa kwamandla avuselelekayo kunye nokungathathi cala kwekhabhoni.
