Sobre IBD

Przezroczyste tlenki przewodzące (TCO), które łączą przezroczystość optyczną i przewodnictwo elektryczne, są niezbędne w cienkowarstwowych technologiach fotowoltaicznych. W niniejszej pracy zbadano syntezę niedomieszkowanych i domieszkowanych (Li, V, Gd) cienkich warstw ZnO metodą chemicznej pirolizy natryskowej, w celu ich integracji w złączach PN. Tomografia atomowa (APT) ujawniła jednorodny rozkład Li. Analizy Ramana, FTIR, SEM, EDX i XPS potwierdziły strukturę i skład warstw. Warstwy domieszkowane wanadem wykazują strukturę wurtzytu, dobrą przezroczystość (400-1200 nm), pasmo wzbronione 3,18-3,26 eV i lepszą mikrotwardość. Domieszkowanie gadolinem modyfikuje morfologię i utrzymuje transmisję optyczną na poziomie 60-80% z przerwą wzbronioną 3,24-3,26 eV. Wreszcie, wytworzone heterozłącza n-ZnO/p-Si wykazują obiecującą wydajność, potwierdzając zainteresowanie warstwami do zastosowań fotowoltaicznych i optoelektronicznych.
