A new type of material for one of the solar cells was proposed by specialists of the Ural Federal University (UrFU) and the Institute of Organic Synthesis of the Ural Branch of the Russian Academy of Sciences together with their colleagues. The compounds found will significantly reduce the cost of solar cell production. The […]
Tandem solar cells made of perovskite and silicon enable significantly higher efficiencies than silicon solar cells alone. Tandem cells from HZB have already achieved several world records. Most recently, in November 2021, HZB research teams achieved a certified efficiency of 29.8 % with a tandem cell made of perovskite and silicon. This […]
Mesoscopic dye-sensitized solar cells (DSCs) were invented in 1990s by Brian O’Regan and Michael Gratzel, taking on the latter’s name – the world-famous Gratzel cells. DSCs convert light into electricity through photosensitizers – dye compounds that absorb light and inject electrons into an array of oxide nanocrystals which subsequently are collected as electric current. […]
To achieve climate neutrality, use of renewable energy sources must be increased massively. “Large solar parks are very important in this connection,” says Nina Munzke. The researcher at KIT’s Institute of Electrical Engineering (ETI) initiated the Solar Park 2.0 project at KIT’s Battery Technical Center. “However, it is a problem to find […]
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 […]
