A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Efficient quantum dot solar panels 11.11.2012

Scientists from the National Renewable Energy Laboratory (NREL, USA) have demonstrated the high efficiency of quantum dot solar panels. Using a process called multiple exciton generation (MEG), the researchers created a solar panel in which each blue photon of absorbed light can generate 30% more electricity than conventional technology.

New solar cells will soon be able to surpass all existing commercial photovoltaic technologies. The new cell demonstrates a high external quantum efficiency (EQE) - more than 100% for photons in the solar spectrum. It should be noted that EQE is not efficiency, but the ratio of hole-electron pairs to the number of photons that hit the solar panel. In turn, the internal efficiency is the ratio of the number of absorbed photons and produced electrons.

So far, no photovoltaic cell has ever approached 100% EQE. Traditional semiconductors produce only one electron from each photon, the rest of the energy is dissipated as heat. At the same time, crystalline nanometer structures such as quantum dots circumvent this limitation, resulting in reduced energy loss and increased electricity output. Due to their microscopic size, quantum dots limit the movement of electrons and do not allow energy to dissipate, which makes it possible to maximize the utilization of photon energy.

The MEG technology uses most of the photon energy efficiently and achieves an EQE of 114%. This allows us to talk about the possibility of creating full-scale solar panels based on quantum dots, which will be significantly more powerful than similar panels based on traditional semiconductors. While the efficiency of the experimental cell is low - only 4,5%. However, this is just a lab sample meant to demonstrate the effect of MEG, not power generation. Scientists believe that in the future, quantum dot solar panels will significantly surpass traditional ones in terms of power and become an environmentally friendly source of new generation energy.
