OREANDA-NEWS A prototype of solar panels based on new metal-free organic dyes was created and tested by scientists from Russia. According to the authors, the development can be integrated into roofs, windows and facades of buildings without compromising their architectural appearance, the press service of the National Research University MIET told RIA Novosti.
The solar cells were manufactured using new metal—free organic dyes as sensitizers - special additives that enhance the photosensitivity of the batteries.
In a broad sense, dye-sensitized solar cells (SCS) are simple devices that can be created from inexpensive materials without the use of expensive equipment and technologies. The cost of their production is twice as low as that of silicon batteries. Typically, such elements consist of two electrodes (one made of highly porous dye—saturated titanium dioxide deposited on a transparent electrically conductive substrate, the second from a thin layer of platinum or carbon on the same substrate) and an iodine-containing electrolyte.
Today, the development and production of SCSB is actively developing abroad. They are embedded in the facades of buildings or used in agriculture, increasing the efficiency of land use by 60 percent. However, there is still no production and large-scale use of dye-sensitized solar panels in Russia.
To solve this problem, a team of scientists from the National Research University "MIET" (NIU MIET), the Institute of Organic Synthesis (IOS) Ural Branch of the Russian Academy of Sciences and the N.S. Kurnakov Institute of General and Inorganic Chemistry (IONH) RAS has developed new metal-free organic π-conjugated dyes and tested them as part of prototypes of dye-sensitized solar cells.
The results of the study will form the basis for the further development of new solar panels that can be integrated into structural elements of buildings, for example, into the roof, windows and facade without compromising their architectural design, said Alexander Steparuk, head of the Laboratory of Advanced Organic Materials of the IOS UrO RAS.
"The main result of our work is that we managed to increase the working area of solar panels by 100 times to 36 cm2 compared to previously created research elements and at the same time maintain the average transmittance at the regulatory level of 35-40 percent. The battery's operating voltage is about one and a half volts, which is a good result. Unfortunately, we have received relatively low current density values, but after optimizing the parameters of the elements, we expect to increase this figure," he said.
