Abstract
U ovome radu istražuje se utjecaj svojstava aktivnog sloja skvaraina i akceptora, derivata fulerena metil ester fulerena [6,6]-fenil-C2-maslačne kiseline, PC71BM u primjeni za hibridne-organske solarne ćelije. Opisani i uspoređeni su dizajn, sinteza i priprava malih molekula, skvaraina, u simetričnom i asimetričnom obliku, i to komercijalnih i pripravljenih u vlastitom aranžmanu. Metodama spektroskopskih analiza, difrakcije rendgenskih zraka te pretražne elektronske mikroskopije, mogu se ispitivati fizikalno kemijska i strukturna svojstva korištenih konstituenata te geometrijska svojstva poput debljine. Na osnovu istih može se podešavati geometrija fotonaponske ćelije, primjerice debljine slojeva i različite konfiguracije mješavina. Fotoaktivni sloj skvaraina i drugih polimera najefikasniji je u konfiguraciji višefaznog heterospoja u kontekstu odnosa debljine i uspješnog prijenosa nosilaca naboja. Međutim, daljnje optimiranje višefaznog heterospoja u funkcionalnoj ćeliji je nužno. Isto se temelji na osnovnim metodama električne karakterizacije poput određivanja I-V karakteristika, gdje se iz ovisnosti struje kratkog spoja i napona otvorenog kruga mogu ustanoviti apsorpcijske karakteristike sloja i energetske razine materijala od kojih je sloj napravljen, prijenos i rekombinacija naboja te efikasnost same solarne ćelije.
Abstract (english)
In this paper, the influence of the properties of the active layer of squaraine and fullerene derivative, [6,6]-phenyl-C2-butyric acid methyl ester, PC71BM in the application for hybrid-organic solar cells is investigated. The molecular design, synthesis, and preparation of small molecules, squaraines, in symmetrical and asymmetrical form, both commercial and prepared in the laboratory, are described and compared. The methods of spectroscopic analysis, X-ray diffraction, and scanning electron microscopy can be used to examine the physical, chemical, and structural properties of the constituents used, as well as geometric properties such as thickness. Based on these, the geometry of the photovoltaic cell can be adjusted, for example, the thickness of the layers and the different configurations of the mixtures. The photoactive layer of squaraine and other polymers is most effective in the configuration of a bulk heterojunction in the context of the thickness ratio and the successful transfer of charge carriers. However, further optimization of the bulk heterojunction in a functional cell is necessary. It is based on basic electrical characterization methods such as determining I-V characteristics, where the absorption characteristics of the layer and the energy level of the material from which the layer is made, charge transfer and recombination, and the efficiency of the solar cell itself can be determined from the dependence of short circuit current and opencircuit voltage.
