ʻO ke kiʻi paʻi kiʻi, i ʻike ʻia he photoresistor a i ʻole light-dependent resistor (LDR), he ʻano pale e hoʻololi i kona kūʻē ʻana ma muli o ka nui o ke kukui e hāʻule ana ma luna.Ke emi nei ke kū'ē o ke kiʻi kiʻi i ka piʻi ʻana o ka māmā a me ka ʻokoʻa.Hoʻohana kēia i nā kiʻi paʻi kiʻi i nā ʻano noi like ʻole, e like me nā mea ʻike kukui, nā kukui alanui, nā mika kukui pahupaʻi, a me nā mea ʻala ʻaihue.
Hana ʻia nā kiʻi paʻi kiʻi me nā mea e like me ka cadmium sulfide, cadmium selenide, a i ʻole ke silika e hōʻike ana i ka photoconductivity.ʻO Photoconductivity ka hiki o kahi mea ke hoʻololi i kona conductivity uila ke ʻike ʻia i ka mālamalama.Ke paʻi ka mālamalama i ka ʻili o kahi photocell, hoʻokuʻu ia i nā electrons, e hoʻonui ai i ke kahe o kēia manawa ma o ke kelepona.
Hiki ke hoʻohana ʻia nā kiʻi paʻi kiʻi ma nā ʻano like ʻole e hoʻomalu i nā kaapuni uila.No ka laʻana, hiki iā lākou ke hoʻohana i ke kukui i ka wā e pōʻeleʻele ai a e hoʻopau iā ia ke mālamalama hou.Hiki iā lākou ke hoʻohana ʻia ma ke ʻano he sensor e hoʻomalu i ka ʻōlinolino o kahi pale hōʻike a i ʻole e kāohi i ka wikiwiki o kahi kaʻa.
Hoʻohana pinepine ʻia nā kiʻi paʻi kiʻi i nā noi waho ma muli o ko lākou hiki ke kū i nā kūlana kūlohelohe koʻikoʻi e like me ka wela wela, ka haʻahaʻa, a me ka radiation UV.He mea maʻalahi hoʻi lākou, e hana ana iā lākou i kumu kūʻai kūpono no nā noi he nui.
I ka hopena, ʻo nā photocells he mea maʻalahi a hoʻohana nui ʻia i ka ʻoihana uila.Loaʻa iā lākou ka hana maʻalahi a me ka haʻahaʻa, e hoʻolilo iā lākou i koho kaulana no nā noi he nui, ʻo ia hoʻi nā mea ʻike kukui, nā kukui alanui, nā mika kukui kamera, nā mea hoʻokele burglar, a me nā mea hou aku.
