NTS is focused on nanotechnology development. Currently there are 3 technologies in development, which will give an innovative improvement to the photon management significantly increasing the efficiency of photovoltaic cells and modules. The most advanced of our technologies is our Functional surface (FS) on PV cells. The current standard micro-structuring (pyramids) of the PV cell surface will be replaced by our nano-structured functional surface with (optimised) optical nano- antennas. This leads to an increase in efficiency of the PV cell by about 10%. The patenting of this technology is filed (Germany and PTC).
The photovoltaic market demands permanently 2 things: A significant increase of efficiency and a reduction of costs of PV cells and modules (in ct / W). Our Technology “Functional surface” is placed in a separate process step (upgrade of existing production lines possible) implemented in the production line of PV cells and increases the efficiency of the cells by about 10%.
Our technology of Functional surface (FS) is implemented in the production of the solar cell and leads to increase of cell efficiency of about 10%. This leads to a quantitative increase in revenue of 10%, as the price is formed performance oriented in ct / W. In addition, the cells produced now belong to a higher performance class and generate additional quality revenues by a higher price in ct / W.
The current standard micro-structuring (pyramids) of the PV cell surface is replaced by our nano-structured functional surface. The Functional surface (FS) works with (optimised in simulations) optical (nano) antennas designed by us. These nano-antennas well couple all the sunlight spectrum (from 280 nm to 1100 nm wavelength) broadband in the cell and keep the photons longer in the cell as the microstructures used so far, because the nano-antennas catch the non-absorbed light in the cell and radiate it back into the cell. This leads to an increase in efficiency of the PV cell by about 10%.
