Zvadaro pindura mubvunzo wacho nemutauro wakafanana: Passage: A photodiode is a p<unk>n junction or PIN structure. Kana photon ine simba rakakwana ichirova diode, inogadzira electron<unk>hole pair. Maitiro aya anozivikanwawo seye mukati photoelectric effect. Kana kupinza kunoitika munzvimbo yekupera kwejunction, kana imwe diffusion kureba kure nayo, vatakuri ava vanotsvairwa kubva kunzvimbo yekubatanidza nemagetsi akavakirwa-mukati enzvimbo yekupera. Saka maburi anofamba achienda kune anode, uye maerekitironi achienda kune cathode, uye photocurrent inogadzirwa.
