Description
508 676 2 innefattande alkalimetallen natrium (Na) eller kalium (K) att bildas ovanpå strukturen före det att CuInSe2-skiktet påläg- ges.
Med ett kopparindiumselenid-skikt menas i detta sammanhang och i patentkraven ett kopparindiumselenid-skikt med olika sammansättningar och med olika legeringsämnen, främst gallium och svavel. Främst avses med kopparindiumselenid föreningarna CuInSe2, CuInxGa1_xSe2 och CuInxGa1_xSySe2_Y.
Nedan beskrives dock uppfinningen med ett kopparindiumsele- nid-skikt enligt formeln CuInSeP Nedan beskrives föreliggande uppfinning närmare delvis i samband med ett på bifogade ritning visat utföringsexempel av uppfinningen, där figur 1 visar en solcellsstruktur.
Föreliggande uppfinning bygger på insikten att påläggning av natrium eller kalium i form av elementärt natrium eller ka- lium eller en förening i vilka dessa grundämnen ingår på den yta på vilken CuInSe2-skiktet skall uppbyggas, d.v.s. ex- empelvis på molybden-skiktet, medför att kornen i den poly- kristallina CuInSe2-filmen blir mer orienterade i en kolumnär struktur. Kornen blir också större och strukturen tätare.
Dessutom minskar resistiviteten i CuInSe2-skiktet, vilket också innebär att en högre effektiv p-dopning erhålles inne- bärande att cellspänningen ökar.
I stället för natrium eller kalium torde andra alkalimetaller medföra samma effekt, i varje fall litium, som har låg atom- vikt.
I figur 1 visas schematiskt ett snitt genom en solcell av typen tunnfilmssolcell. Tunnfilmssolceller uppbyggs på sub- strat som kan vara stora, exempelvis 1 X 0.4 meter. Härvid förefinns ett mycket stort antal celler över substratytan, vilka är elektriskt sammankopplade. Figur 1 visar endast en 508 676 3 del av en sådan cell. Tillverkningstekniken för att fram- ställa ett stort antal separata men elektriskt förbundna celler på en substratyta är välkänd och beskrives inte närma- re här.
En solcell vid vilken uppfinningen kan tillämpas kan vara uppbyggd på följande sätt. Vanligen är substratet 1 en glas- skiva av lämplig tjocklek, exempelvis 2.0 mm. Först sputtras ett skikt 2 av molybden (Mo) på glasytan. Molybdenskiktet ut- gör bakkontakt och pluspol i den färdiga cellen. Molybden- skiktet kan ha en tjocklek av exempelvis 1000 nanometer. Där- efter pålägges ett CuInSe2-skikt 3 med en tjocklek av exem- pelvis 2500 nanometer. Ovanpå detta skikt 3 pålägges först ett skikt 4 av kadmiumsulfid (CdS) med en tjocklek av exem- pelvis 50 nanometer, varefter en kontakt i form av transpa- rent dopat zinkoxidskikt (ZnO) 5 med en tjocklek av exempel- vis 500 nanometer pålägges.
När solljus infaller mot solcellen uppstår en elektrisk spän- ning mellan kontakten 5 (Zn0), som är minuspol, och bakkon- takten 2.
Nedan beskrives uppfinningen med natrium som exempel. Detsam- ma gäller dock andra alkalimetaller. I figur 1 anges skiktet betecknat 6 som Na. För det fall andra alkalimetaller avses skall dessa utgöra nämnda skikt 6.
Enligt uppfinningen bringas ett skikt 6 innefattande en alka- limetall, i exemplet natrium (Na), att bildas ovanpå metall- skiktet 2, d.v.s. ovanpå molybdenskiktet i ovanstående exem- pel, före det att CuInSe2-skiktet 3 pålägges.
Enligt en föredragen utföringsform bringas natrium att på- läggas genom förångning av natriumselenid (Na2Se) på bakkon- takten, d.v.s. metallskiktet.
Enligt en annan föredragen utföringsform bringas kalium att 508 676 4 påläggas genom förångning av kaliumselenid (K2Se) på bakkon- takten, d.v.s. metallskiktet.
Enligt en annan föredragen utföringsform sputtras alkalime- tallen, i exemplet natrium, på samtidigt som bakkontakten då denna utgöres av molybden.
Enligt en ytterligare föredragen utföringsform bringas skik- tet innefattande alkalimetallen, i exemplet natrium, att ha en tjocklek av 50 till 500 nanometer.
Enligt en utföringsform bringas skiktet att innefatta även syre (0).
Det har visat sig att när CuInSe2-skiktet pålägges ovanpå skiktet innefattande natrium eller kalium kommer natrium respektive kalium i allt väsentligt att försvinna från me- tallkontaktens yta. När CuInSe2-skiktet pålagts återfinnes natrium respektive kalium dels i korngränserna i CuInSe2- skiktet, dels på detta skikts yta. När sedan cds-skiktet pålägges med en våt process försvinner natrium- respektive kaliumföreningen från ytan, förutsatt att natrium- respektive kaliumföreningen är löslig i aktuell vätska.
Detta förfarande ger vid den som exempel angivna solcellen en ytterst överraskande höjning av verkningsgraden, nämligen med omkring 25 %. En dylik solcell där uppfinningen inte tilläm- pas har typiskt en verkningsgrad av 12 %. Genom tillämpning av uppfinningen ökar verkningsgraden till 15 %.
Ovan har föreliggande uppfinning beskrivits i anslutning till en viss solcellsstruktur. Emellertid kan föreliggande uppfin- ning tillämpas vid andra strukturer, där exempelvis bakkon- takten inte utgöres av molybden utan av en annan lämplig me- tall, såsom wolfram, nickel, titan och krom.
Dessutom kan andra substrat än glas innehållande natrium an- 508 676 vändas. Exempelvis kan glas, som inte innehåller natrium an- vändas, liksom glas innehållande natrium vilka försetts med en diffusionsbarriär mot natrium på den yta, där bakkontakten uppbygqs- Föreliggande uppfinning skall därför inte anses begränsad till ovan angivna utföringsformer, utan kan varieras inom dess av bifogade patentkrav angivna ram.
