Fa'idodi da rashin amfani na ɓangarorin sirara-fim na hasken rana

Kwayoyin hasken rana na bakin ciki suna amfani da su sosai a cikin wuraren aikin gona na photovoltaic da wuraren daukar hoto da ke buƙatar watsa haske. Shin kun san mene ne fa'ida da rashin amfani da siraran fina-finan hasken rana? Shekaru nawa ne wannan simintin fim ɗin hasken rana ya cika?

A halin yanzu, sel siraran-fim na hasken rana da ake dasu galibi sun haɗa da: cadmium telluride thin-film solar cell, jan ƙarfe indium gallium selenide thin-film solar cell, da amorphous silicon thin-film solar cell.

1. Amfanin sirara-fim solar Kwayoyin

(1) Darajar hasken rana tare da yawan sha.

GaAs na III-V ne na kayan aikin semiconductor, kuma gibin kuzarinsa shine 1.4eV, wanda shine kawai ƙimar ƙimar ƙimar hasken rana, wanda ya fi dacewa da daidaitawa da bakan hasken rana.

(2) Babban juriya na zafin jiki.

A karkashin yanayin 250 ° C, aikin juyawa na photoelectric har yanzu yana da kyau sosai, kuma mafi girman ingancin canjin hoto shine kusan 30%, wanda ya dace da yanayin zafi mai zafi mai mai da hankali kan ɓangarorin hasken rana.

(3) Karancin farashi.

Yin amfani da wafers na siliki a matsayin maɓalli, hanyar heteroepitaxial na fasahar MOCVD hanya ce mai ban sha'awa don rage farashin ƙwayoyin GaAs.

2. Rashin lahani na siriri-fim hasken rana Kwayoyin

(1) Sauƙin shayarwa.

Tsarin girma na ɓangarorin hasken rana na sirara-fim yana ƙayyade cewa ƙananan-fim hasken rana sel suna da saurin lalacewa, don haka juriya na ruwa na kayan da ke ɗauke da fluorine da ake buƙata don ɗaukar sel na hasken rana na bakin ciki-fim yana da kusan sau 9 ƙarfi fiye da na ƙwayoyin silicon crystalline.

(2) Ragewar hoto.

Ragewar sel sirara-fim na hasken rana shine kusan 30%.

(3) Canjin aikin jujjuyawar sirara-fim hasken rana ya yi ƙasa.

Saboda babban ƙarfin juzu'i na ƙwayoyin hasken rana na membrane, yawancin su suna bayyana ne kawai a cikin ƙananan sikelin da samfuran lantarki masu sassauƙa.

(4) Cadmium telluride a cikin kayan samarwa abu ne mai guba.

Cadmium wani abu ne mai guba mai tsananin gaske wanda ke taruwa a cikin sarkar abinci kamar mercury, wanda ya saba wa ra'ayin kasancewa mai mu'amala da muhalli, aminci da rashin guba. Cibiyoyi da dakunan gwaje-gwaje da yawa suna neman hanyoyin da za su dace da muhalli, ingantaccen inganci, kuma masana'antun hasken rana suna bincika hanyoyin da za su dawo da sake sarrafa kayan da ke ɗauke da cadmium don magance matsalolin muhalli.
