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.

Ultrathin aluminum oxide protective layer adds stability to perovskite solar cells

Dec 07, 2016

Researchers at Eindhoven University of Technology (TU/e) and research institute ECN (part of the Solliance collective) have found that adding a thin layer of aluminum oxide helps protect a perovskite solar cell against humidity, as well as add a yield boost of 3%.

The scientists covered the sensitive layer of perovskite with a few atomic layers of aluminum oxide to protect against degradation caused by humidity. These layers are contained within the solar cell, between the layers of perovskite and electric contact. The researchers chose aluminum oxide (Al2O3) since it can form immediately on any kind of surface. The team explained that despite the fact that Al2O3 has electrically insulating properties, it can still be used as a buffer layer between the semi-conductive perovskite and the conductive contacts by limiting the thickness of the layer to one nanometer or less. This way, charge carriers can then tunnel electrically through the insulator layer.

Oxford PV secures £8.1 million in further investment

Dec 07, 2016

Oxford Photovoltaics recently announced an equity investment of £8.1 million (around US $10.2 million), adding to the £8.7 million first close investment announced in October 2016. The bulk of this investment will reportedly come from three new strategic investors: Statoil ASA, Legal & General Capital and a technology-focused, innovative family fund investor.

Oxford PV recently announced the acquisition of a pilot line site in Germany and, in the beginning of December 2016, announced a Joint Development Agreement with a major solar panel manufacturer to scale the technology towards commercialization. This additional injection of funds will hopefully help accelerate these development activities as well as support the next generation product research in the UK.

Oxford PV to collaborate with mysterious global solar cell manufacturer

Dec 04, 2016

Oxford PV has announced a joint development agreement with an unnamed global solar cell and module manufacturer, as an additional step in the company's quest for commercialization of its perovskite solar technology.

The two companies will will work together to move Oxford PV's technology from lab scale to manufacturing-ready status, with most of the work taking place at the pilot line site in Germany that Oxford PV acquired recently.

Australian researchers achieve the highest efficiency rating with the largest perovskite solar cells to date

Dec 04, 2016

Researchers at Australia's University of New South Wales announced the achievement of the highest efficiency rating with the largest perovskite solar cells to date. The 12.1% efficiency rating was for a 16 cm2 perovskite solar cell, the largest single perovskite photovoltaic cell certified with the highest energy conversion efficiency, and was independently confirmed by the international testing centre Newport Corp, in Bozeman, Montana. The new cell is at least 10 times bigger than the current certified high-efficiency perovskite solar cells on record.

The researchers also achieved an 18% efficiency rating on a 1.2 cm2 single perovskite cell, and an 11.5% for a 16 cm2 four-cell perovskite mini-module, both independently certified by Newport. The team estimated that it will be be able to "get to 24% within a year or so".

Warwick U team designs tin-based perovskite solar cells

Nov 30, 2016

Researchers at the University of Warwick in the UK designed an environmentally friendly perovskite solar cell in which lead is substituted for tin with reportedly undiminished rates of performance but at cheaper cost and with lower toxicity.

The team stated that tin-based perovskites are much more stable than previously thought, and also render solar power cheaper, safer and possibly even more commercially attractive. "The device structure can be greatly simplified without compromising performance, which leads to the important advantage of reduced fabrication cost" the scientists say.

Interview from Dr. Lioz Etgar, from the Hebrew University's perovskite lab

Nov 28, 2016

Dr. Lioz Etgar obtained his Ph.D. at the Technion–Israel Institute of Technology, and completed his post-doctoral research with Prof. Michael Grätzel at EPFL, Switzerland. Dr. Etgar was the first to demonstrate the possibility to work with the perovskite as light harvester and hole conductor in the solar cell which result in one of the pioneer publication in this field.

Dr. Etgar is now leading the Perovskite solar lab in the Hebrew University in Jerusalem, Israel. Etgar’s research group focuses on the development of innovative solar cells. Etgar is searching for new excitonic solar cells architectures while designing and controlling the inorganic light harvester structure and properties to improve the photovoltaic parameters. Etgar was kind enough to answer a few questions we had for him.

A new perovskite material may open the door to next-gen data storage

Nov 24, 2016

EPFL scientists have developed a new perovskite material whose magnetic order can be rapidly changed without disrupting it due to heating. This novel material may potentially be used to build next-generation hard drives.

EPFL's new perovskite for memory storage image

The EPFL team synthesized a ferromagnetic photovoltaic material. This material is a modified version of perovskite, that exhibits unique properties that make it particularly interesting as a material to build next-generation digital storage systems. The researchers explain that they have basically created the first magnetic photoconductor; This new crystal structure combines the advantages of both ferromagnets, whose magnetic moments are aligned in a well-defined order, and photoconductors, where light illumination generates high density free conduction electrons.
