In this work we developed several strategies
to enhance solar cells which lead to stronger
sunlight absorption with less active material
and thereby also reducing costs. This is
accomplished through utilizing nanoscale
architectures, which geometry can be tailored
to modify the flow of light for optimal
absorption. Since sunlight comprises of
photons with a broad range of wavelength
(colors), ensuring a complete absorption
requires sophistications in the nanostructure
design due to its wavelength dependent
interaction with light. To address this
challenge we utilized combinations of different
periodic nanostructures with one another and
also with disordered rough light diffusers.
Aside from our absorption enhancement work,
we
also
investigated
light
emission
enhancement utilizing periodically placed
metal nanoantennas. We demonstrate how
hybrid plasmonic-photonic modes that arise in
such system can be used to control and
enhance emission over an extended spatial
region. This is relevant in solar cell
enhancement schemes which convert the
unused portion of sunlight into the color range
suitable for optimal usage.
Having investigated various light management
schemes to enhance solar cells, we proceeded
to examine the limiting factors which hinder
efficient electrical current extraction from
polycrystalline silicon thin film solar cells of a
few micrometers thick. We identified the
conditions in which this more economical
material gives the desired solar cell
performance.
Curriculum Vitae
Aimi Abass is born in Jakarta 12 July 1985. In
2010, he finished his master studies in the
program:
Erasmus
Mundus
Master
in
Photonics for which he obtained a full
scholarship for.
Since September 2010, he joined the solar
cells group in the department of Elektronica
en Informatiesystemen (ELIS) in Ghent
University as
a doctoral student. He was
supported in his doctoral work by the IWT
Institute for the Promotion of Innovation by
Science and Technology in Flanders via the
SBO project “SilaSol,”
and by the
Interuniversity Attraction Poles program of
the Belgian Science Policy Office under Grant
No. IAP P7-35 “photonics@be”. During this
time, he worked with various collaborators
within and outside of Belgium.
The results of his doctoral work were
published
in
ten
international
journal
publications (with one more under review)
and presented in
sixteen international
conferences (two of which are invited talks).
