The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

Efficient solar cell made from conventional silicon 03.05.2021

Scientists from the Fraunhofer Institute for Solar Energy Systems (ISE) have created a solar cell with a conversion efficiency of 26% from classic single-crystal silicon, which has become a world achievement. The new technology is simpler than the previously proposed Interdigitated Back Contact (IBC) technology with contacts on the back of the cells and promises to approach the theoretical limit of silicon when converting solar energy into electricity.

Today, the vast majority of solar panels are produced from ordinary single-crystal silicon - over 90%. It would be tempting to increase the efficiency of such panels without complicating the technology and increasing the cost of production. The IBC technology promised to help with this, when both current-carrying contacts in the cells are created on the back side of the cell, which does not obscure the panel and allows better use of the volume of the element in the process of knocking out electrons by photons. Unfortunately, although IBC panels are close to 26% in terms of efficiency, their production is quite expensive, so they turned out to be unclaimed.

Researchers at ISE have been able to bring the efficiency of single-crystal cells closer to 26% in another way and even promise to go further - to achieve an efficiency value of 27% with a theoretical limit for silicon of 29,4%. This was achieved due to the special arrangement of conductive contacts on both sides of the cells, but these are not all changes.

The new cell is based on the TOPCon contact, which is a tunnel oxide passivated contact. The new development differs from the panels produced today in that the TOPCon contact is not located on top, but lies along the entire back side of the cell. This approach also made it possible to alloy with boron not the entire front surface, but only places under the second ordinary contact remaining there, which simplified and reduced the cost of production. Thus, the new cell was named TOPCoRE (element with TOPCon contact on the back side).

In addition to high efficiency, the new element delivers more voltage, and its operation is accompanied by lower losses due to surface recombination and due to efficient electron transport.
