Teza

I. INTRODUCTION
One of the main strategic engineering and R&D directions
in the development of modern society is the creation of
environmentally friendly renewable energy sources based on
solar energy conversion into electricity. With the use of
semiconductor nanomaterials for photovoltaic converters of
solar cells will increase their effectiveness and reducing the
cost of both the solar cells and their maintenance.
That is why the joint research work of scientists of the
Academy of Sciences of Moldova and the National Technical
University of Ukraine "KPI" were dedicated to the study of
energy efficiency lighting systems using semiconductor
nanomaterials for photovoltaic converters of solar energy.
II. SEMICONDUCTOR NANOMATERIALS BASED SOLAR
CELLS AND THEIR USE IN LIGHTING SYSTEMS OF
PREMISES
According to the specification of research on "Energy
efficient conversion of light radiation of the sun into electrical
energy by means of photosensitive semiconductor sensors
(solar cells)" based on studies of porous and nanoporous
silicon with controllable functional properties were
performed: analysis of existing methods of converting solar
light energy into electrical and thermal energy, development
of methods of creating electro thermal solar collectors in the
world and in Ukraine particularly, review designs of
semiconductor modules to form a solar cell according to
specification [1].
Also the main types of semiconductor material for light
radiation into electrical energy conversion, photoelectric
converters based on porous silicon, Korax SOLAR firm
technology, methods for the formation and development of
solar photovoltaic converters were compared.
The photovoltaic converter model with distributed potential
barriers, taking into account the effects generation and
recombination, quantum-mechanical tunnelling through a
potential barrier and system of contacts was proposed and
photovoltaic parameters results obtained from calculation of
some structures contact systems using a modified PC-1D
computer software were presented.
In Figure the experimental characteristics are captured the
output power of solar cell during the day from 8 hours and 08
min to 18 h 21 min and solar cell voltage during the day from
8 hours and 08 minutes to 17hod 36 min in Chisinau
09/19/2011.
III. CONCLUSION
Thin nanostructured films increases the efficiency of
photoelectric conversion when using for contacts systems and
antireflection coatings of solar cells.
When developing a control algorithm of hardware and
software complex lighting facilities on the basis of solar cells
one should adaptively change the parameters of complex
models.
