I-photocell, eyaziwa nangokuthi i-photoresistor noma i-resistor encike ekukhanyeni (LDR), iwuhlobo lwe-resistor eshintsha ukumelana kwayo ngokusekelwe kwinani lokukhanya eliwela kuyo.Ukumelana ne-photocell kuncipha njengoba amandla okukhanya akhuphuka futhi ngokuphambene nalokho.Lokhu kwenza ama-photocells asebenziseke ezinhlelweni ezihlukahlukene, okuhlanganisa izinzwa zokukhanya, izibani zasemgwaqweni, amamitha okukhanya kwekhamera, nama-alamu okugqekeza.
Amaseli ezithombe enziwe ngezinto ezifana ne-cadmium sulfide, i-cadmium selenide, noma i-silicon ebonisa ukusebenza kwe-photoconductivity.I-Photoconductivity yikhono lempahla ukuguqula ukuqhutshwa kwayo kukagesi lapho kuvezwe ekukhanyeni.Lapho ukukhanya kushaya ebusweni be-photocell, kukhipha ama-electron, okwandisa ukugeleza kwamandla eseli.
Ama-photocell angasetshenziswa ngezindlela ezahlukahlukene ukulawula amasekhethi kagesi.Isibonelo, zingasetshenziselwa ukukhanyisa isibani lapho kuba mnyama futhi zicinywe lapho kukhanya futhi.Angasetshenziswa futhi njengenzwa ukulawula ukukhanya kwesikrini sokubonisa noma ukulawula isivinini semoto.
Ama-photocell avame ukusetshenziswa ezinhlelweni zangaphandle ngenxa yekhono lawo lokumelana nezimo zemvelo ezinzima njengamazinga okushisa aphakeme, umswakama, nemisebe ye-UV.Abuye angabizi kakhulu, okwenza abe yisixazululo esingabizi kakhulu sezinhlelo zokusebenza eziningi.
Sengiphetha, ama-photocells ayizici ezihlukahlukene futhi ezisetshenziswa kabanzi embonini ye-electronics.Zinokwakhiwa okulula nokushibhile, okuzenza ukukhetha okudumile kwezinhlelo zokusebenza eziningi, okuhlanganisa izinzwa zokukhanya, izibani zasemgwaqweni, amamitha okukhanya kwekhamera, ama-alamu okugqekeza, nokunye.
