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.

Fluxim releases a new software tool to simulate large area perovskite solar cells

Oct 24, 2016

Switzerland-based R&D tools provider Fluxim released a new simulation tool called Laoss. Laoss is aimed specifically for large area organic electronic devices - such as large OLED TV panels and perovskite solar cells.

Fluxim says that the Laoss software can be used to design optimal electrode lay-outs of any shape with and without current carrying grids. According to Fluxim, a carefully designed electrode layout avoids non-uniformities that arise due to the resistance of the electrode and charge injecting layers.

Dyesol announces plan to collaborate with CSIRO to develop commercially viable perovskite PV technology

Oct 23, 2016

Dyesol logo Australia-based Dyesol has announced the signing of a letter of intent (LOI) to collaborate with the Commonwealth Scientific and Industrial Research Organisation (CSIRO) in the development of perovskite solar cells (PSC).

The LOI creates a non-binding framework for collaboration and coordination between the two organizations. The collaboration aims to be a step towards the development of commercially viable PSC technology. CSIRO is currently the 4th largest shareholder in Dyesol. The two have worked together in the past, collaborating in 2010 on materials for dye sensitized solar cells. Since then, Dyesol has shifted to focus on PSC development.

Perovskite-perovskite solar cell design that can be printed on plastic could prove highly stable and efficient

Oct 23, 2016

Researchers at Stanford University and Oxford University have reportedly combined two perovskite materials to produce a stable solar cell with efficiency over 20% that can be printed on a plastic substrate. The teams have developed four and two-terminal perovskite-perovskite tandem solar cells with ideally matched bandgaps. Each cell is printed on glass, but the same technology could be used to print the cells on plastic.

Oxford U and Stanford U present perovskite-perovskite solar cells

They developed an infrared absorbing 1.2eV bandgap perovskite, FA0.75Cs0.25Sn0.5Pb0.5I3, that delivers 14.8% efficiency. By combining this material with a wider bandgap FA0.83Cs0.17Pb(I0.5Br0.5)3 material, a monolithic two terminal tandem cell provides efficiencies of 17.0% with over 1.65 V open-circuit voltage. The team has also mechanically stacked four terminal tandem cells and obtain 20.3% efficiency.

Oxford PV raises £8.7 million to advance perovskite solar cell technology

Oct 19, 2016

Oxford Photovoltaics logo imageUK-based Oxford Photovoltaics, founded in 2010 as a spin-off from the University of Oxford, has announced an equity investment of £8.7 million (around US $10.6 million), provided by a combination of new and existing shareholders as the first portion of a Series C funding round. Further investment is expected before the end of 2016.

The funding will be used to help extend Oxford PV's position in the use of its perovskite technology to significantly enhance the performance and economic returns achievable from existing solar PV technologies. A portion of the funding has already been earmarked to develop a demonstration line to showcase the technology to manufacturers, bringing the firm one step closer to commercialization.

4DS Memory developed a 40nm RRAM memory cell based on perovskite materials

Oct 18, 2016

4DS Memory logoUS-based RRAM developer 4DS Memory announced that it developed a working 40nm RRAM memory cells. The 4DS memory cell is constructed using an advanced perovskite material, which has the same crystal structure as the inorganic compound calcium titanium oxide.

4DS Memory's development was achieved in collaboration with HGST, a subsidiary of Western Digital. 4DS has been collaboration with HGST for the past two years under a joint development agreement (JDA). When the JDA commenced, 4DS memory cells were at 800 nm. The JDA was renewed in July 2016 for a further 12 months and is focused on optimizing scalability and cycling endurance or RRAM cells for the mobile and cloud gigabyte silicon storage market.

Oxford team realizes reduced toxicity solvent for 'greener' perovskite solar cells

Oct 10, 2016

Scientists at Oxford University have developed a solvent system with reduced toxicity that can be used to manufacture perovskite solar cells, which may clear one of the barriers to the commercialization of a technology.

By combining methylamine and acetonitrile, researchers have developed a clean solvent with a low boiling point and low viscosity that quickly crystallises perovskite films at room temperature and could be used to help coat large solar panels with the material.

NREL team achieves 10.77% efficiency for perovskite cell made with quantum dots

Oct 10, 2016

Researchers from the US National Renewable Energy Laboratory (NREL) have achieved 10.77% conversion efficiency with perovskite solar cells made from quantum dots with no organic components.

The result was achieved with a thin film made of nanocrystals of cesium lead iodide (CsPbI3). The team discovered a method to keep the crystal structure in the all-inorganic perovskite material stable at room temperature, something that was previously possible only at temperatures exceeding 600 degrees Fahrenheit. The use of methyl acetate as an anti-solvent to remove excess unreacted precursors proved a crucial step in increasing the nanocrystals’ stability.
