Translucent flexible solar cells

26.12.2013

Hendrik Bolink from the University of Valencia (Spain) and his colleagues experimented with organic compound molecules from methane and ammonia tails, as well as iodine and lead atoms. Spanish physicists have created translucent solar cells based on thin films of an organic analogue of the mineral perovskite, which are highly efficient and can bend, which allows them to be used as a tinted coating for glasses, according to an article in the journal Nature.

In recent years, scientists have created several exotic materials that can increase the efficiency of solar cells by several times. In particular, the attention of physicists is increasingly attracted by the mineral perovskite, whose thin films are semiconductors that convert light energy into electricity well.

Hendrik Bolink from the University of Valencia (Spain) and his colleagues experimented with organic compound molecules from methane and ammonia tails, as well as iodine and lead atoms. Having studied the chemical properties of this substance, the authors of the article came to the conclusion that it is similar in its properties to perovskite and can capture photons of light just as well and convert their energy into electricity.

The authors of the article tested this hypothesis by evaporating small amounts of methylammonium iodide (CH3NH3I) and lead iodide (PbI2) in a vacuum chamber containing a small plate. Vapors of these substances "settled" on the plate and connected with each other, forming a thin layer of perovskite.

Then the scientists packed this film into a "sandwich" of two pieces of conventional organic semiconductors - PCBM and PolyTPD, used in the manufacture of organosilicon photocells, inserted electrodes into it and checked it out. It turned out that their invention absorbed about 12% of the energy of light, which is comparable to the best performance for thin-film solar cells.

The main advantage of the invention of Bolink and his colleagues is that such solar cells are translucent and flexible. Coupled with their microscopic thickness, this allows such photovoltaic cells to be used as glass coatings capable of generating electricity or heat.

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 ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Water unmanned taxi 21.11.2021

A new mode of transport was tested in the canals of Amsterdam.

Specialists from the Computer Science and Artificial Intelligence Laboratory of the Massachusetts Institute of Technology (USA) launched the first self-navigating fully autonomous robotic boats.

There can be five people on the boat. Engineers believe that such boats can be used both as passenger transport and for delivering goods or, for example, transporting garbage. The boat is powered by a battery that lasts for 10 hours of battery life. Such devices can be charged wirelessly while in the dock.

While moving, the boat uses lidar and multiple cameras to provide a 360-degree view. Navigation is carried out in the same way as in a car - using GPS.
