Panasonic has achieved the world’s highest energy conversion efficiency of 16.09% for a perovskite solar module (aperture space 802 cm2: 30-cm x 30-cm x 2-mm thick) by growing light-weight technology using a glass substrate and a large-area coating technique primarily based on inkjet printing. This was carried out as a part of the project of the New Energy and Industrial Technology Development Organization (NEDO), which is engaged on the “Development of Technologies to Reduce Power Generation Costs for High-Performance and High-Reliability Photovoltaic Power Generation” to advertise the widespread adoption of solar power technology.
This inkjet-based coating technique that may cowl a big space reduces manufacturing prices of modules. In addition, this large-area, light-weight, and high-conversion efficiency module permits for producing solar power extremely effectively at areas the place standard solar panels have been tough to put in, comparable to façades.
Going ahead, NEDO and Panasonic proceed to enhance perovskite layer supplies, aiming to attain excessive efficiency similar to that of crystalline silicon solar cells and set up applied sciences for sensible software in new markets.
By specializing in the inkjet coating technique that allows the uncooked materials to be coated exactly and uniformly, Panasonic utilized that technology to every layer of the solar cell together with perovskite layer on glass substrate and realized excessive power conversion efficiency for a large-area module.
