ʻO ke kumumanaʻo o ka hoʻololi ʻana i ka ikehu lā i nā ʻenehana like ʻole: ʻo ka ikehu māmā e hoʻoulu i nā electrons e hana i ka ikehu uila;ʻO ka neʻe ʻana o nā electrons e hana i ke au uila, a laila hoʻololi i ka ikehu māmā i ikehu uila.
ʻO ke kaʻina hana o ka hoʻololi ʻana i ka ikehu lā i ka ikehu uila ua kapa ʻia ʻo photovoltaic power generation.ʻO ke kumu o ka hana mana photovoltaic ʻo ia ka hoʻohana ʻana i nā kiʻi i ka lā e hoʻoulu ai i nā electrons i nā cell photovoltaic e hana i kēia manawa.ʻO ke kelepona kiʻi kiʻi kiʻi he mea semiconductor maʻamau i haku ʻia me nā wafer silika.
Loaʻa i ka wafer silika ʻelua mau mea, phosphorus-doped silicon a boron-doped silicon, nona nā hale uila like ʻole.Ke pā ka lā i ka wafer silika, pā nā photon i nā electron i loko o ka wafer silicon, e hoʻohauʻoli iā lākou mai ko lākou mau ʻātoma a hana i nā lua electron-hole i loko o ka wafer.ʻO ka silicon doped me ka phosphorus he semiconductor n-type, a ʻo ka silicon doped me ka boron he semiconductor ʻano-p.Ke hoʻohui ʻia nā mea ʻelua, ua hoʻokumu ʻia kahi māla uila, a ʻo ke kahua uila ka mea e neʻe ai nā electrons a hana i kahi au.
