A research team, affiliated with UNIST has succeeded in achieving a power conversion efficiency (PEC) of 23.50% in a perovskite-silicon tandem solar cell built with a special textured anti-reflective coating (ARC) polymeric film. According to the research team, the PCE of the device with the ARC film was sustained for 120 hours, maintaining 91% […]
Two-dimensional covalent organic frameworks (2D COFs) are a new class of organic semiconductors, and have recently demonstrated great potential for solar fuel production. They are generally formed from the ordered p-p stacking of molecular layers, and usually possess periodic columnar p-arrays that can facilitate the interlayer charge transfer. Furthermore, the ordered assembly of organic […]

A recent analysis reveals the daunting number of variables that must be considered when attempting to link agricultural production and solar energy. Federal scientists know that solar panels and crops can coexist and provide mutual benefits in certain scenarios. A recent study from the National Renewable Energy Laboratory (NREL) confirms this, but also shows that […]
Early last year, I thought the wind and solar price hikes were a fluke. After all, one of the constants in my decade-plus covering energy was that the prices of wind and solar were in a constant state of decline. not anymore The trend is unmistakable. Prices are going up, a lot. But the good […]
