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.

Perovskites may bring organic diode lasers one step closer to reality

Nov 22, 2017

Researchers from Penn State and Princeton University have made strides in creating a diode laser based on a perovskite material that can be deposited from solution on a laboratory benchtop.

Organic diode lasers, that are extremely hard to make, are sought after since they have many advantages. First, because organic semiconductors are relatively soft and flexible, organic lasers could be incorporated into new form factors not possible for their inorganic counterparts. While inorganic semiconductor lasers are relatively limited in the wavelengths, or colors, of light they emit, an organic laser can produce any wavelength a chemist cares to synthesize in the lab by tailoring the structure of the organic molecules. This tunability could be very useful in applications ranging from medical diagnostics to environmental sensing.

Detection of nanoscale changes in hybrid perovskite crystals may help improve the efficiency of PSCs

Nov 22, 2017

A team of researchers, that includes researchers from the AMOLF Institute in the Netherlands and Argonne National Laboratory and is led by the University of California San Diego, has observed nanoscale changes in hybrid perovskite crystals that could offer new insights into developing low-cost, high-efficiency solar cells.

Using X-ray beams and lasers, the researchers studied how hybrid perovskites behave at the nanoscale level during operation. Their experiments revealed that when voltage is applied, ions migrate within the material, creating regions that are no longer as efficient at converting light to electricity. "Ion migration hurts the performance of the light absorbing material. Limiting it could be a key to improving the quality of these solar cells," said a member of the Sustainable Power and Energy Center at UC San Diego.

Solliance achieves a new efficiency record for perovskite-based PV technology

Nov 22, 2017

Solliance has achieved a new world record for Perovskite Solar Cell technology demonstrated on industrially applicable Roll-to-Roll (R2R) processes of 13.5% conversion efficiency at cell level. The group stressed that the records were achieved in a factory setting, using an industrially scalable process.

Solliance has achieved the conversion efficiency of 13.5% and module-level aperture area conversion efficiency of 12.2% for perovskite-based photovoltaics using industrially-applicable, roll-to-roll production processes. By further optimizing and re-validating processes that were earlier developed buy Solliance, the performance at both the cell and module level have been improved.

Greatcell secures a $825,000 grant for perovskite solar cell commercialization

Nov 19, 2017

Greatcell logo imageGreatcell Solar, developer of solar technologies, was awarded 700,000 euro (about $825 million USD) in a European Union Horizon 2020 project known as Apolo. The grant to Greatcell's application has occurred through its 100% Italian subsidiary, Greatcell Solar Italy located in Rome, that aims to commercialize perovskite solar technology.

Much of the work involved will investigate advanced technology for higher efficiencies, longer life, and improved encapsulation of PSC-enabled flexible substrates, such as metals and polymers. These are all critical in the successful translation of the 3rd generation PSC photovoltaic (PV) technology from the laboratory to the factory and satisfying PV industry accreditation (IEC 61215).

Empa and ETH Zurich create a perovskite-based stacked image sensor

Nov 19, 2017

Researchers from Empa and ETH Zurich have developed a perovskite-based sensor prototype that absorbs light almost optimally and is also cheap to produce.

Stacked formation for image sensors image

The team explains that the working mechanism of the human eye, not very different than various image sensors, is based on three different types of sensory cells for the perception of color: cells that are respectively sensitive to red, green and blue alternate in the eye and combine their information to create an overall colored image. However, this mechanism has inherent limitations: as each individual pixel can only absorb a small part of the light spectrum that hits it, a large part of the light is lost. In addition, the sensors used in various applications have basically reached the limits of miniaturization, and unwanted image disturbances can occur; these are known as color moiré effects and have to be removed from the finished image.

Saule Technologies to demonstrate A4-paper-sized, flexible, printed perovskite solar cells

Nov 12, 2017

Saule Technologies will be presenting a flexible, printed, perovskite photovoltaic module the size of an A4 sheet of paper, for the first time, at the IDTechEx Show on November 15-16th in Santa Clara, CA. The operating Saule module is printed on an ultrathin plastic foil able to charge personal electronic devices, demonstrating one of the many possible applications of these perovskite solar cells. The prototype industry-scale production line is estimated to begin in 2018.
