Researchers at the University of Liverpool, UK, have discovered the factors that limit the conductivity of fluorine-doped tin dioxide, which may be an active catalyst for the development of solar glass coatings.
Physicists at the University of Liverpool have identified the factors that limit the conductivity of fluorine-doped tin dioxide.
The researchers found that for every two fluorine atoms that provide extra free electrons, one occupies a normally unoccupied lattice site in the tin dioxide crystal structure, and each of these so-called 'interstitial' fluorine atoms All trap a free electron to become a negative charge, which reduces the electron density by half and also leads to an increase in the remaining free electron scattering, which in turn leads to a low conductivity of the fluorine-doped tin dioxide.
With this important discovery, it is possible to find ways to improve the transparency of the coating and to increase the conductivity by a factor of 5 to reduce the cost and improve the performance of a large number of applications such as touch screens, LEDs, photovoltaic cells and energy-saving windows etc. The research team is currently looking for New alternative dopants to avoid the above-mentioned adverse factors.
In addition to the University of Liverpool physicists, scientists from the University of Surrey Ion Beam Center, University College London and the international glass maker NSG Group also participated in the study.
