Microquanta announces 14.24% efficiency with large-area perovskite solar module

Microquanta Semiconductor logo The China-based Microquanta says its research team achieved a 14.24% conversion efficiency record for a large-area (200x800cm2) perovskite solar module. The device has reportedly passed testing by the European Solar Test Installation agency. Also, Microquanta announced a 20 MW perovskite module pilot line.

The business has focused on perovskite cell and module R&D from day one. Last year, Microquanta achieved a lab conversion efficiency record of 17.9% (17.3% stable rate) with its perovskite solar module, and the company then turned to large-area devices.

Perovskites may help fight global plastic pollution

A multi-institutional team of scientists has designed a new catalytic method in order to battle plastic pollution on a global scale. The team's new catalytic method could prove useful for selectively converting discarded plastics into higher quality products.

"We asked ourselves the question, ​‘Plastic, plastic everywhere: What can we do about it in terms of chemical recycling?’” said Max Delferro, group leader of the Catalysis Science Program in the Chemical Sciences and Engineering division at the U.S. Department of Energy’s (DOE’s) Argonne National Laboratory. ​“So, we assembled a talented team with DOE’s Ames Laboratory and researchers from top universities to provide a solution.” The partners from academia included Northwestern University, Cornell University, University of South Carolina and University of California, Santa Barbara".

Perovskites may be used for various thermoelectric applications

A Cornell-led team of scientists has discovered a crystalline material with ultralow thermal conductivity, which could lead to the design of novel energy conversion materials and devices.

After studying a popular hybrid perovskite and identifying the mechanisms for its low thermal conductivity, Zhiting Tian, assistant professor of mechanical and aerospace engineering at Cornell, turned her attention to a hybrid perovskite analogue, methylammonium bismuth iodide (CH3NH3)3Bi2I9, which she hypothesized would have an even lower thermal conductivity because of the unique disconnected structure of its inorganic molecules.

Addition of biological material boosts performance of perovskite solar cells

An international team of researchers, including ones from Penn State, Columbia University, University of Toledo, Northeastern University in the U.S and Carl von Ossietzky University in Germany, designed next-gen solar cells that mimic photosynthesis with a biological material, by adding the protein bacteriorhodopsin (bR) to perovskite solar cells.

“These findings open the door for the development of a cheaper, more environmentally friendly bioperovskite solar cell technology,” said Shashank Priya, associate vice president for research and professor of materials science at Penn State. “In the future, we may essentially replace some expensive chemicals inside solar cells with relatively cheaper natural materials.”

Korea Electric Power Corp. (KEPCO) develops efficient flat-type perovskite solar cell

Korea Electric Power Corp. (KEPCO) recently stated that it has developed a flat-type perovskite solar cell with "the world's best photoelectric conversion efficiency".

KEPRI, an R&D subsidiary of KEPCO, reportedly succeeded in producing perovskite solar cell with 20.4% photoelectric conversion efficiency, surpassing the 20.1% efficiency of flat solar cells announced so far.

Tin-containing perovskite solar cells achieve 30% power conversion

A team of researchers from Stanford University and University of Colorado Boulder, led by Professor Michael McGehee, demonstrated how to dramatically improve the stability of tin-containing perovskite materials used in stacked solar cells, allowing for up to 30% power conversion efficiency.

These stacked perovskite solar cells could be an inexpensive alternative to silicon solar panels that operate at only 20% efficiency. McGehee and his team have been developing perovskite stacking methods for years in an attempt to increase power conversion efficiency.
