After a lot of head-scratching and brain storming, the guys at theResearch Center for Photovoltaics at the National Institute of AdvancedIndustrial Science and Technology (AIST) came up with a record-breakingflexible solar submodule. Using a CIGS thin film, a solar cell material, this monolithically integrated flexible solar cell submodule has theworld’s highest photovoltaic energy conversion efficiency of 15.9%.
These types of solar modules are the heart-throb of solartechnology, since unlike their paneled up counterparts, they can beeasily fitted onto uneven surfaces. An energy conversion of more than10% for these flexible solar submodules has never been attained before,due to which efficiency suffered. However, with this breakthrough,lightweight and flexible solar cell technology will find more uses andwider applications in future.
