Description
Organic materials have been found to offer various, promising advantages
for photovoltaic (PV) devices like flexibility and the potential
of low-cost/large scale production. Hybrid devices combine these advantages
with the chemical/physical stability of inorganic materials
and, thus, overcome the issue of limited lifetimes of purely organic
cells. Poly(styrene-block-ethylene oxide) templated sol-gel chemistry
is used to synthesize high surface-to-volume ratio, mesoporous titania
thin films, which allows for precise structure control and an increased
amount of interface. The n-type, electron conducting titania thin film
serves as a basis for novel organic material studies. The studies aim to
introduce new material combinations to the field of hybrid PV and to
open up pathways for enhanced efficiency in terms of energy conversion
and band alignment. Thin film spectral absorption characterization
is carried out via UV/Vis measurements. Furthermore, morphological
characterization is realized via SEM, XRD and TOF-GISANS to extract the efficiency of backfilling and the crystal structure of the system.
