Ụkpụrụ nke ịtụgharị ike anyanwụ n'ime ike dị iche iche bụ: ike ọkụ na-akpali electrons ịmepụta ike eletrik; mmegharị nke electrons na-etolite ọkụ eletrik, si otú ahụ na-agbanwe ike ọkụ ka ọ bụrụ ike eletrik.
Usoro nke ịtụgharị ike anyanwụ n'ime ike eletrik ka a na-akpọ mmepụta ike fotovoltaic. Ụkpụrụ nke mmepụta ike fotovoltaic bụ iji foton na ìhè anyanwụ na-akpalite electrons na sel fotovoltaic iji mepụta ugbu a. Igwe fotovoltaic bụ ngwaọrụ semiconductor na-ejikarị ọtụtụ wafer silicon.
Igwe ọkụ silicon nwere ihe abụọ, silicon-doped silicon na silicon boron-doped, nke nwere usoro eletrọnịkị dị iche iche. Mgbe ìhè anyanwụ rutere n'ọkụ silicon, photons kụrụ electrons na silicon wafer, na-akpali ha site na atom ha na ịmepụta ụzọ abụọ electron na wafer. Silicon doped with phosphorus bụ ihe n-ụdị semiconductor, na silicon doped na boron bụ p-ụdị semiconductor. Mgbe ejikọtara ha abụọ, a na-emepụta oghere eletrik, ebe ọkụ eletrik na-eme ka ndị electrons na-emegharị ma na-emepụta ugbu a.
