Project description:

Professor Teodor Gotszalk together with a team from the Department of Nanometroligy will lead
research under the project "Electronic nanometrology of nanowires used in
energy applications "carried out in cooperation with the Laboratory of Physics of
Interfaces and Thin Films, Ecole Polytechnique in Paris.
The research will concern the measurement of the photovoltaic response of silicon nanofibers
integrating in their structure the p-n junction. The nanofibers form a kind of nanodate, na
which directs the light that generates the electrical response. Because the light in such
the system reaches the p-n junction from all sides, their greater efficiency should be expected.
With relatively low production costs of this type of cells, it makes them attractive
solutions, especially in systems for generating energy supplying portable energy
electronics.
The research conducted at the Department of Nanometrology is related to single metrology
photovoltaic nanofiber. These measurements will be carried out using advanced methods
near interaction microscopy and electron microscopy. Fibers several hundred and a half long
with a diameter of several dozen nanometers will be mounted on specialized substrates
enabling their polarization and addressing. It will be located on their surface
a near interaction microscope blade probing the electrical response of the nanofiber.
The nanofibers will be produced by the French partner of the Polonium program, i.e.
laboratory led by Dr. Martin Foldyna. Seating individual fibers on
substrates, experiments conducted in the mode of Kelvin microscopy and flow resistance
will be implemented at the Department of Nanometrology of the Wrocław University of Science and Technology.
