easy and inexpensive amorphous, poly- and microcrystalline semi-conductors

and the structure of solar elements prepared on the basis of conductors

rapid degradation under the influence of temperature and lighting, useful work

The smallness of the coefficient and the efficiency of work and time the reason for the increase in the price of electricity
is happening In general, it is an old-fashioned silicon-based battery 25% efficiency of elements in laboratory conditions
gacha, gallium arsenide asosli kuyosh elementlarining foidali ish the coefficient can be increased to 32% in laboratory conditions [3].

Despite this, the current demand for preparation technology and reduce the cost of electricity produced
forces to search for elements. Such solar elements
"Dye sensitized solar cells (DSSC- Dye sensitized solar cell) or "Grazel elements" can be given as an example. This is the sun technology of preparation of elements, their introduction and the cost of improvements, their use and production
this area with several conveniences of release attracts specialists [4-6].
Currently, this type of sun is created by Japanese scientists the maximum efficiency of the elements is 13%, durability
and the term is indicated to be more than 10 years. DSSC solar cells because they are made of organic dyes and polymer substances more expensive than traditional solar cells
to be 10-15 times cheaper than the purchased electricity
determined.

DSSC Sun is one of the first in Uzbekistan to do this

The technology of preparation of elements is described

Main part


Used in making DSSC solar cells
Materials: We use the following chemicals in the preparation of DSSC solar cells
substances used in erithmalardan Kuyos elementining production of electrodes in Sigma Aldrich, USA released: titanium dioxide with a molecular size of 15 nm
(TiO2) P90 and (TiO2) P25 with a size of 21 nm, polyethylene glycol (PEG), triton-X100, fluorine-doped tin oxide grown glass
(FTO) and platinum, a product of Supelco Analytical, USA (Pt) were used.
Polymethyl methacrylate (PMMA) in electrolyte preparation,
