ʻO nā pono a me nā pōʻino o nā kiʻiʻoniʻoni lahilahi solar

Hoʻohana nui ʻia nā cell solar kiʻiʻoniʻoni kiʻiʻoniʻoni i loko o nā hale ʻōmaʻomaʻo mahiʻai photovoltaic a me nā keʻena photovoltaic e pono ai ka lawe māmā. ʻIke paha ʻoe i nā mea maikaʻi a me nā pōʻino o nā kiʻiʻoniʻoni ʻoniʻoni solar cell? ʻEhia makahiki ka lōʻihi o kēia paneli lā?

I kēia manawa, ʻo ka nui o nā pūnaewele kino kiʻiʻoniʻoni i kēia manawa: cadmium telluride thin-film solar cell, copper indium gallium selenide thin-film solar cell, a me amorphous silicon thin-film solar cell.

1. ʻO nā pono o nā kiʻiʻoniʻoni lahilahi solar

(1) Ka waiwai o ka lā me ke kiʻekiʻe absorption rate.

No nā GaAs i nā mea semiconductor pūhui III-V, a ʻo kona ʻākea ikehu he 1.4eV, ʻo ia wale nō ka waiwai o ka nui o ka absorption rate o ka lā, ʻoi aku ka maikaʻi no ka hoʻohālikelike ʻana me ka spectrum solar.

(2) Kūleʻa wela kiʻekiʻe.

Ma lalo o ke kūlana o 250 °C, ʻoi aku ka maikaʻi o ka hoʻololi ʻana o ka photoelectric, a ʻo kona kiʻekiʻe kiʻekiʻe kiʻekiʻe o ka hoʻololi ʻana i ka photoelectric e pili ana i 30%, kahi kūpono loa no nā kiʻi ʻoniʻoni ʻoniʻoni ʻoniʻoni kiʻekiʻe.

(3) Ke kumukuai haahaa.

Ke hoʻohana nei i nā wafer silika ma ke ʻano he substrates, ʻo ke ʻano heteroepitaxial o ka ʻenehana MOCVD he ala hoʻohiki e hōʻemi i ke kumukūʻai o nā cell GaAs.

2. Nā hemahema o nā kiʻiʻoniʻoni lahilahi

(1) He mea hoʻonanea maʻalahi.

ʻO ke ʻano o ka ulu ʻana o nā kiʻiʻoniʻoni ʻoniʻoni ʻoniʻoni e hoʻoholo ana i ka hiki ke hoʻokaʻawale ʻia nā kiʻiʻoniʻoni ʻoniʻoni i ka deliquescent, no laila ʻo ke kūpaʻa wai o nā mea i loko o ka fluorine i koi ʻia e hoʻopili i nā kiʻiʻoniʻoni ʻoniʻoni ʻoniʻoni ma kahi o 9 mau manawa ʻoi aku ka ikaika ma mua o ko ka crystalline silicon cell.

(2) Hoʻemi kiʻi ʻia.

ʻO ka attenuation o nā kiʻi ʻoniʻoni ʻoniʻoni solar ma kahi o 30%.

(3) He haʻahaʻa ka hoʻololi ʻana o nā kiʻi ʻoniʻoni ʻoniʻoni.

Ma muli o ke kiʻekiʻe o ka hoʻololi ʻana o ka membrane solar cell, ʻike ʻia ka hapa nui o lākou i nā huahana uila liʻiliʻi a maʻalahi.

(4) ʻO Cadmium telluride i loko o ka mea hana he mea ʻawaʻawa.

ʻO ka Cadmium he mea ʻawaʻawa loa e hōʻiliʻili ʻia i loko o ke kaulahao meaʻai e like me ka mercury, he mea kūʻē i ka manaʻo o ka pili ʻana i ke kaiapuni, palekana a ʻaʻole ʻona. Ke ʻimi nei nā keʻena he nui a me nā hale hana i nā mea ʻoi aku ka maikaʻi o ke kaiapuni, ʻoi aku ka maikaʻi, a ke ʻimi nei nā mea hana o ka lā i nā ala e hoʻihoʻi hou ai a hana hou i nā mea i loaʻa i ka cadmium e hoʻoponopono i nā pilikia kaiapuni.
