Perovskite-Info: the perovskite experts

Perovskite-Info is a news hub and knowledge center born out of keen interest in the wide range of perovskite materials.

Perovskites are a class of materials that share a similar structure, which display a myriad of exciting properties like superconductivity, magnetoresistance and more. These easily synthesized materials are considered the future of solar cells, as their distinctive structure makes them perfect for enabling low-cost, efficient photovoltaics. They are also predicted to play a role in next-gen electric vehicle batteries, sensors, lasers and much more.

Solar-Tectic presents perovskite/crystalline silicon thin-film tandem solar cell technology

Jul 12, 2016

Solar-Tectic logo imageSolar-Tectic, a thin-film specialist with patented technology primary focused on developing highly textured, single crystal semiconductor films on glass or other inexpensive substrates, presented a paper at the "Fifth International Symposium on Energy Challenges and Mechanics (ECM5) - working on small scales" in Inverness, Scotland, making public for the first time details of its perovskite/crystalline silicon thin-film tandem solar cell technology for highly efficient and inexpensive solar cells.

While reports of perovskite/silicon tandem solar cells are common, it would seem that there have been much less mentions of perovskite/thin-film silicon. Crystalline thin-film silicon promises to be less expensive than silicon wafer technology due to low temperature processing and less material use. Also, the entire process is non-toxic since tin (Sn) is used in the perovskite material, rather than lead (Pb).

Solar cell efficiency improved by perovskite crystals

Jul 11, 2016

Researchers from Los Alamos National Laboratory, Rice University and Northwestern University have been working on modifying perovskites' manufacturing technique and producing a new variety of 2D layered perovskite with exceptional strength and increased power transformation capability.

Using a spin-casting technique, the team managed to create layered crystals whose electrons flow vertically down the material without being blocked, midlayer, by organic cations. The researchers stated that “the new 2D perovskite is both more efficient and more stable, both under constant lighting and in exposure to the air, than the existing 3D organic-inorganic crystals”.

Perovskite-based colloidal solutions make for efficient LEDs

Jul 11, 2016

Researchers at Nanyang Technological University in Singapore have fabricated high-performance green light-emitting diodes based on colloidal organometal perovskite nanoparticles. The devices have a maximum luminous efficiency of 11.49 cd/A, a power efficiency of 7.84 lm/W and an external quantum efficiency of 3.8%. This value is said to be about 3.5 times higher than that of the best colloidal perovskite quantum-dot-based LEDs previously made.

The team developed a simple way to make a series of colloidal (CH3NH3)PbX3 nanoparticles with an amorphous structure that can be tuned to emit light in the ultraviolet to near-infrared range. They studied the photoluminescence properties of the nanoparticles and found that the PLQE of the perovskite NP film is much higher than that of the bulk film. They then made the highly efficient green LED.

DOE scientists may increase perovskite solar cells' efficiency to up to 40%

Jul 06, 2016

Researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory have found that it may be possible to boost energy conversion rates perovskite-based solar modules by as much as 40%.

DOE scientists may bring perovskite solar cell efficiency to 40%

Using an atomic microscope, the researchers observed multifaceted surfaces in perovskite solar cells. Some of the grains, which were about 200 microns in width, had sharply formed multi-angled facets, while others were poorly formed. The poorly formed facets had energy conversion efficiencies approaching 31%, which beats today's most optimistic photovoltaic efficiency rates of around 22%.

The World Economic Forum chooses Perovskite as one of the top emerging technologies in 2016

Jun 29, 2016

The World Economic Forum, best known for its annual winter Davos meeting, in collaboration with Scientific American, has published its top 10 Emerging Technologies 2016 list. This list highlights technological advances that the forum members believe have the power to improve lives, transform industries and safeguard the planet.

Perovskite solar cells are included in the WEForum's list. It is explained that perovskite materials offer three advantages over silicon-based solar cells: they are easier to producer, can be used anywhere (as they can be made to produce thin, light, flexible and transparent cells) and are highly efficient.

“PeroBOOST” project focuses on development of solar cells from perovskites

Jun 21, 2016

Aixtron logo imageAixtron announced that it will be pushing forward with research on perovskite solar cells within the “PeroBOOST” project together with University of Cologne, Enerthing, Lunovu, SOLUXX, the Center for Organic Electronics Cologne (ZOEK), the Fraunhofer ISE Laboratory and Service Center Gelsenkirchen, and Duisburg-Essen University.

The basis for this three-year project (03/2016-02/2019) is the discovery of the superb properties of organo-perovskite materials for efficient solar cells. The “PeroBOOST” project will be focusing above all on two aspects and aiming to develop these further: Efficient and stable lead-free perovskite solar cells, and scaling up methods and techniques.

Perovskites assist in breaking bandwidth record for data communication

Jun 19, 2016

Researchers from the King Abdullah University of Science and Technology (KAUST) have designed a system that uses an innovative color converter based on luminescent materials known as phosphors, which are commonly used in LED lights, and combines them with nanocrystals of perovskite. This system has achieved record bandwidth, providing a data transmission rate of 2Gbit per second.

Researchers break bandwidth record for data communication using perovskites image

The major achievements in this work are breaking the record for data communication using visible light and, even more impressively, producing white light with a very high color-rendering index of 89, by designing a special color converter based on hybrid perovskite nanocrystals. The work demonstrates white light as both a lighting source and a system for ultra-high-speed data communications.
