New Technique Improves Stability, Efficiency of Solar Cell Modules
Written by AZoMJan 28 2021
A group of scientists from the Okinawa Institute of Science and Technology Graduate University (OIST) has used a new fabrication method to create perovskite solar modules that have enhanced efficiency and stability with fewer defects.
Perovskite solar cell devices require multiple layers to function. The active perovskite layer absorbs sunlight and generates charge carriers. The transport layers transport the charge carriers to the electrodes, releasing a current. The active perovskite layer is formed from many crystal grains. The boundaries between these grains, and other defects in the perovskite film, such as pinholes, lower the efficiency and lifespan of the solar devices.

Researchers from the Okinawa Institute of Science and Technology Graduate University (OIST) have created perovskite solar modules with improved stability and efficiency by using a new fabrication technique that reduced defects. Their findings were published on the 25th January in Advanced Energy Materials.
Perovskites are one of the most promising materials for the next-generation of solar technology, soaring from efficiencies of 3.8% to 25.5% in slightly over a decade. Perovskite solar cells are cheap to produce and have the potential to be flexible, increasing their versatility. But two obstacl
Researchers focus on specific neurons that make reaching-and-grasping tasks possible
Research conducted at the Okinawa Institute of Science and Technology Graduate University (OIST), has looked at the importance of specific neurons for seemingly simple, day-to-day tasks that involve reaching for and grasping objects. The study was published in
Cell Reports. We focused on the neurons located in the basal ganglia, said Professor Gordon Arbuthnott, who leads OIST s Brain Mechanisms for Behavior Unit. This part of the brain is connected to the cerebral cortex, which is involved in motor function. And neurons, or nerve cells, are specialized cells that act as the building blocks of the nervous system - they connect input from the outside world to movement in our muscles.
