Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: A photodiode is a p<unk>n junction kana PIN chimiro. Apo fotoni ine simba rakakwana inorova diode, inogadzira maerekitironi ane maburi maviri. Muitiro uyu unozivikanwawo sechinhu chomukati chinokonzerwa nemagetsi. Kana kunwiwa kuchiitika munharaunda yekupera kwejojo, kana kureba kumwe kwekuparadzira kubva pairi, vatakuri ava vanotsvairwa kubva kunzvimbo yekubatana nemunda wemagetsi wakavakirwa munharaunda yekupera. Nokudaro makomba anoenda kunzvimbo yeanode, uye maerekitironi anoenda kunzvimbo ye cathode, uye chiedza chinobudiswa. Huwandu hwesimba rinopinda mu photodiode ihwo huwandu hwesimba rerima (riripo rinogadzirwa pasina chiedza) uye photocurrent, saka simba rerima rinofanira kuderedzwa kuti uwedzere kunzwisisika kwechigadzirwa.  Mubvunzo: Chii chinofanira kurova diode kuitira kuti pave neelectron-hole pair?
