I-photocell, eyaziwa ngokuba yi-photoresistor okanye i-resistor exhomekeke kukukhanya (LDR), luhlobo lwe-resistor eguqula ukuchasana kwayo ngokusekelwe kumlinganiselo wokukhanya owela kuyo.Ukuchasana kwe-photocell kuncipha njengoko ukuqina kokukhanya kukhula kwaye ngokuchaseneyo.Oku kwenza ukuba ii-photocells zibe luncedo kwiinkqubo ezahlukeneyo, kubandakanywa izivamvo zokukhanya, izibane zesitrato, iimitha zokukhanya kwekhamera, kunye nee-alam zokuqhekeza.
Iifotocells zenziwe ngezinto ezifana ne-cadmium sulfide, i-cadmium selenide, okanye i-silicon ebonisa i-photoconductivity.I-Photoconductivity kukukwazi kwezinto eziphathekayo ukutshintsha umbane wayo xa ibonakaliswe ekukhanyeni.Xa ukukhanya kubetha umphezulu we-photocell, kukhupha ii-electron, ezandisa ukuhamba kwangoku kwiseli.
Iifotocells zinokusetyenziswa ngeendlela ezahlukeneyo zokulawula iisekethe zombane.Umzekelo, zisenokusetyenziswa ukukhanyisa isibane xa kuba mnyama kwaye sisicime xa kukhanya kwakhona.Zingaphinda zisetyenziswe njengenzwa yokulawula ukuqaqamba kwesikrini sokubonisa okanye ukulawula isantya semoto.
Iifotocells ziqhele ukusetyenziswa kwizicelo zangaphandle ngenxa yokukwazi ukumelana neemeko ezirhabaxa zokusingqongileyo ezinje ngobushushu obugqithisileyo, ukufuma, kunye nemitha ye-UV.Kananjalo azibizi kakhulu, nto leyo ezenza zibe sisisombululo esineendleko eziphezulu zezicelo ezininzi.
Ukuqukumbela, ii-photocells zinezinto ezininzi kwaye zisetyenziswa ngokubanzi kwishishini le-elektroniki.Zinolwakhiwo olulula nolunexabiso eliphantsi, nto leyo ezenza zibe lukhetho oludumileyo kwizicelo ezininzi, kubandakanywa izivamvo zokukhanya, izibane zesitrato, iimitha zokukhanya kwekhamera, iialamu zokugqekeza, nokunye.
