Mokuna 2 ʻano o nā pūnaewele lā

ʻO ka pono o ka hoʻololi ʻana o ka pila hui Gallium arsenide (GaAs) Ⅲ ~ V a hiki i ka 28%, he kūpono loa ka ʻāpana optical band gap o ka mea hui GaAs, a me ka pono omo kiʻekiʻe, kūpaʻa ikaika i ka irradiation, ʻaʻole ʻike i ka wela, kūpono no ka hana ʻana i nā pila hoʻokahi hui kiʻekiʻe. Eia nō naʻe, ʻaʻole pipiʻi ke kumukūʻai o nā mea GaAs, no laila e kaupalena ana i ka hoʻolaha ʻana o nā pila GaAs i kahi nui.

He kūpono ka pila ʻili lahilahi keleawe indium selenide (CIS no ka pōkole) no ka hoʻololi photoelectric, ʻaʻohe recession photoelectric, ka pono o ka hoʻololi ʻana a me ka polysilicon, e like me ke kumukūʻai haʻahaʻa, ka hana maikaʻi a me ka maʻalahi o ke kaʻina hana a me nā pono ʻē aʻe, e lilo ia i kuhikuhi koʻikoʻi no ka hoʻomohala ʻana o nā cell solar i ka wā e hiki mai ana. ʻO ka pilikia wale nō ke kumu o nā mea, ma muli o ka indium a me ka selenium he mau mea kakaikahi, no laila, ʻo ka hoʻomohala ʻana o ia mau pila e kaupalena ʻia.
(3) nā pūnaewele lā polymer organik
ʻO nā polymers organik ma kahi o nā mea inorganic kahi kuhikuhi noiʻi o ka hana ʻana o nā cell solar. Ma muli o ka maʻalahi o nā mea organik, maʻalahi ka hana ʻana, ākea nā kumu waiwai, haʻahaʻa ke kumukūʻai a me nā pono ʻē aʻe, no laila ka hoʻohana nui ʻana i ka ikehu lā, ka hāʻawi ʻana i ka uila haʻahaʻa he mea nui loa ia. Eia nō naʻe, ua hoʻomaka wale nei ka noiʻi ʻana i nā mea organik e hoʻomākaukau i nā cell solar, inā paha he ola lawelawe, a i ʻole ka pono o ka pila ʻaʻole hiki ke hoʻohālikelike ʻia me nā mea inorganic, ʻoi aku hoʻi nā pila silicon, inā hiki ke hoʻomohala ʻia i mea nui o ka huahana, akā e ʻimi ʻia hoʻi i ka noiʻi hou aku.
(4) nā pūnaewele lā nanocrystalline (nā pūnaewele lā i hoʻonaninani ʻia e ka dye)
Ua hoʻomohala hou ʻia nā Nano Ti02, nā cell solar ikehu kemika crystalline, me ke kumukūʻai haʻahaʻa a me ke kaʻina hana maʻalahi a me ka hana paʻa. Ua paʻa kona pono photovoltaic ma mua o 10%, ʻo ke kumukūʻai hana he 1/5 ~ 1/10 wale nō o nā cell solar silicon, hiki ke piʻi aku ke ola ma mua o 20 mau makahiki. Eia nō naʻe, ʻoiai ua hoʻomaka wale ka noiʻi a me ka hoʻomohala ʻana o ia mau cell, ua manaʻo ʻia e hele mālie mai lākou i ka mākeke i ka wā e hiki mai ana.
