Loaʻa ka manaʻolana no ka hoʻonui ʻana i ka maikaʻi o nā panela solar silicon maʻamau

ʻAʻole ia he mea huna e loaʻa nā palena o nā panela lā silika kaulana i ka maikaʻi o kā lākou hoʻololi ʻana i ke kukui i uila. ʻO kēia no ka mea e kīkēkē ana kēlā me kēia photon i hoʻokahi electron, ʻoiai ua lawa ka ikehu o kahi ʻāpana māmā e kīkē i ʻelua electron. Ma kahi noiʻi hou, hōʻike nā ʻepekema MIT e hiki ke lanakila i kēia palena kumu, e hoʻokaʻawale i ke ala no nā cell solar silicon me ka ʻoi aku ka maikaʻi.

ʻO ka hiki o ke kiʻi kiʻi kiʻi i ʻelua mau electrons ua hoʻāpono ʻia ma kahi o 50 mau makahiki i hala. Akā ua hana hou ʻia nā hoʻokolohua kūleʻa mua i 6 mau makahiki i hala. A laila, ua hoʻohana ʻia kahi cell solar i hana ʻia me nā mea kūlohelohe ma ke ʻano he hoʻokolohua. He mea hoʻowalewale ke neʻe aku i ka silikoni ʻoi aku ka maikaʻi a me ka nui, kahi mea a nā ʻepekema i hoʻokō ai i kēia manawa ma o ka nui o ka hana.

I ka wā hope loa hoʻokolohua ua lanakila i ka hana ʻana i kahi cell solar silicon, ua hoʻonui ʻia ka palena o ka manaʻo mai 29,1% a i 35%, ʻaʻole kēia ka palena. ʻO ka mea pōʻino, no kēia mea, pono e hana ʻia ka cell cell i ʻekolu mau mea like ʻole, no laila ʻaʻole hiki ke loaʻa me ka silikon monolithic. I ka hui ʻana, ʻo ka cell solar he sandwich i hana ʻia me nā mea kūlohelohe. ʻo ka tetracene ma ke ʻano o kahi kiʻiʻoniʻoni ma luna, ka kiʻiʻoniʻoni ʻoi aku ka lahilahi (he mau atoms) o ka hafnium oxynitride a, ʻoiaʻiʻo, he wafer silika.

Hoʻopili ka papa tetracene i ka photon ikaika nui a hoʻololi i kona ikehu i ʻelua hoʻohiwahiwa hele hewa i ka papa. ʻO kēia nā mea i kapa ʻia he quasiparticles nā mea hoʻohauʻoli. Ua ʻike ʻia ke kaʻina hana kaʻawale ʻo singlet exciton fission. Ma kahi hoʻohālikelike, hana like nā excitons e like me nā electrons, a hiki ke hoʻohana ʻia kēia mau hauʻoli e hoʻohua i ke au uila. ʻO ka nīnau pehea e hoʻololi ai i kēia mau hauʻoli i ke silika a ma waho?

Ua lilo kahi ʻāpana lahilahi o ka hafnium oxynitride i ʻano alahaka ma waena o ka kiʻiʻoniʻoni tetracene ili a me ke silika. ʻO nā kaʻina hana i loko o kēia papa a me nā hopena ma luna o ke silika e hoʻohuli i nā excitons i electrons, a laila hele nā ​​mea a pau e like me ka mea maʻamau. Ua hiki i ka hoʻokolohua ke hōʻike i ka hoʻonui ʻana i ka pono o ka cell solar i ka spectra uliuli a me ka ʻōmaʻomaʻo. Wahi a ka poʻe ʻepekema, ʻaʻole kēia ka palena no ka hoʻonui ʻana i ka pono o kahi cell solar silicon. Akā ʻo ka ʻenehana i hōʻike ʻia e lawe i nā makahiki e kūʻai ʻia.
