Selelekela se sekgutshwane saTube ea photo ea mahlaseli a kotsi:

Phototube ea Ultraviolet ke mofuta oa tube ea ho lemoha mahlaseli a kotsi a nang le phello ea photoelectric. Mofuta ona oa photocell o sebelisa cathode ho hlahisa photoemission, li-photoelectron li fallela ho anode tlas'a ts'ebetso ea tšimo ea motlakase, 'me ionization e etsahala ka lebaka la ho thulana le liathomo tsa khase ka har'a tube nakong ea ionization; lielektrone tse ncha le li-photoelectron tse entsoeng ke ts'ebetso ea ionization ka bobeli li amoheloa ke anode, ha li-ion tse ntle li amoheloa ke cathode ka lehlakoreng le fapaneng. Ka hona, photocurrent potolohong ea anode e kholo ka makhetlo a 'maloa ho feta ea phototube ea vacuum. Li-photocell tsa Ultraviolet tse nang le litlamorao tsa photovoltaic tsa tšepe le khase li ka lemoha mahlaseli a ultraviolet a pakeng tsa 185-300mm le ho hlahisa photocurrent.

Ha e na kutloelo-bohloko mahlaseling a kantle ho sebaka sena sa spectral, joalo ka khanya ea letsatsi e bonahalang le mehloli ea mabone a ka tlung. Kahoo ha ho hlokahale ho sebelisa thebe ea leseli e bonahalang joalo ka lisebelisoa tse ling tsa semiconductor, kahoo ho bonolo ho e sebelisa.
Phototube ea mahlaseli a kotsi a letsatsi e ka lemoha mahlaseli a fokolang a mahlaseli a letsatsi. E ka sebelisoa oli ea mafura a boiler, tlhokomelo ea khase, alamo ea mollo, sistimi ea motlakase bakeng sa tlhokomelo ea tšireletso ea lehalima ea transformer e sa hlokomeloeng, jj.
