ʻO ka hoʻolauna ʻana o nā Cu nanopowders i ka hoʻohana ʻana o nā cell solar:
ʻO ke kelepona lā he mea hana e hoʻololi i ka ikehu o ka lā i ikehu uila.ʻO ke kumu nui ka hoʻohana ʻana i ka hopena photoelectric o semiconductors.Ke ʻā mai ka lā ma luna o ke kelepona lā, hoʻopili ka mea kelepona i ka mālamalama hanana o kekahi lōʻihi nalu, a hauʻoli nā kiʻi kiʻi e hana i nā lua electron photogenerated, a laila hoʻohuli i ka ikehu māmā i ikehu uila.Akā ke ʻā mai ka lā ma luna o ka cell solar, ʻike ʻia ka lā, hoʻomoʻa ʻia a hoʻouna ʻia.Pehea e hōʻemi ai i ka noʻonoʻo ʻana o ka lā o ka lā, no ka loaʻa ʻana o nā pālua electron-hole hou aʻe a hoʻonui i kona pono hoʻololi photoelectric, ua lilo ia i mea nui e hoʻoponopono ʻia.
Ma o ka hoʻomau mau ʻana a me ka noiʻi ʻana o nā mea noiʻi ʻepekema, ua manaʻo ʻia ke ʻano o ka hoʻohana ʻana i nā ʻāpana nano-metal e hoʻoulu i ka resonance plasmon surface me ka mālamalama hanana ma ka ʻili o nā cell solar.Hiki i ka resonance plasmon o ka ʻili ke hoʻopaʻa i ka ikehu o nā kiʻi.Ke like a kokoke paha ka alapine o ke kukui hanana i kona alapine oscillation, e hoʻopaʻa ʻia ke kukui hanana kokoke i ka plasmon ili, ma laila e hoʻonui ai i ka absorption o ka mālamalama, no laila e hoʻonui ʻia ka ikehu o ka lā i loaʻa i ka cell solar. ʻo ia ka mea i kapa ʻia ʻo surface plasmon enhanced solar cell.Metallic keleawe i maikai thermal conductivity, a me ka nanofluid piha me ka nano keleawe pauka (Cu nanoparticle) 'aʻole wale maikaʻi thermal conductivity, akā, e hōʻike ikaika absorption hana i loko o ka ike kukui bana, i mea kūpono loa e like me ka holo ana ka wai hana no ka pololei absorption. nā mea ʻohi lā.ʻO ka hoʻomākaukau ʻana i nā nanofluids ke kumu o nā pilikia nanofluid āpau, ka mea nui e pili ana i ka hoʻomākaukau controllable o nā nanoparticles a me ka hoʻopuehu paʻa o nā nanoparticles i ka wai kumu.
ʻO ka ʻike ma luna no ka ʻike wale nō.No ka ʻikepili noi maoli, pono e hoʻāʻo ʻia lākou e like me kāu ʻano ponoʻī.

Pono e mālama ʻia nā ʻāpana Nano Copper (Cu) i ka sila, e pale i ka māmā, kahi maloʻo.Maikaʻi ka mālama ʻana i ka lumi wela.
