Japan鈥檚 NEDO and Panasonic achieve 16.09% efficiency for large-area perovskite solar cell module

Panasonic Corporation has achieved an energy conversion efficiency of 16.09% for a perovskite solar module (Aperture area 802 cm2: 30 cm long x 30 cm wide x 2 mm thick) by developing lightweight technology using a glass substrate and a large-area coating method based on inkjet printing. This was carried out as part of the project of the New Energy and Industrial Technology Development Organization (NEDO), which is working on the “Development of Technologies to Reduce Power Generation Costs for High-Performance and High-Reliability Photovoltaic Power Generation” to promote the widespread adoption of solar power generation. This inkjet-based coating method that can cover a large area reduces manufacturing costs of modules. In addition, this large-area, lightweight, and high-conversion efficiency module allows for generating solar power highly efficiently at locations where conventional…

New quality control method could help scale up perovskite solar cells

Researchers from Australia’s ARC Center of Excellence in Exciton Science, Monash University, Wuhan University of Technology and CSIRO Energy have shown how critical imperfections invisible to the naked eye can be detected by shining blue light onto the cells and recording the infrared light that bounces back. Perovskite solar cells bathed in blue light, and responding in infrared. Credit: Exciton Science This “trick of the light” may help detect imperfections in perovskite solar cells, opening the door to improved quality control for commercial production. When attempting to scale up perovskite cells, performance often deteriorates due to nanoscale surface imperfections resulting from the way the materials are made. As the number of detects grows, the amount of solar power generated per square centimeter drops. Now,the Australian research team has come up…
