Scientists at Martin-Luther-Universität Halle-Wittenberg (MLU) are boosting the photovoltaic effect in ferroelectric-paraelectric superlattices. The team is reporting the photovoltaic effect of ferroelectric crystals can be increased by a factor of 1,000 if three different materials are arranged periodically in a lattice. The researchers achieved this by creating crystalline layers of barium titanate, strontium titanate and […]

University of Utah researchers identified crucial electrical noise signals in solar cells that are completely invisible to conventional noise-measuring methods. They were also able to pinpoint the likely physical processes causing the noise, which often results in a loss of energy and lower efficiency. The physicists used cross-correlation noise spectroscopy to measure miniscule fluctuations in […]

Open Image…Save ImageOpen Image (using #TmpD/ia)… Rice University engineers have created microscopic seeds for growing remarkably uniform 2D perovskite crystals that are both stable and highly efficient at harvesting electricity from sunlight. Halide perovskites are organic materials made from abundant, inexpensive ingredients, and Rice’s seeded growth method addresses both performance and production issues that have held back halide perovskite photovoltaic […]

Open Image…Save ImageOpen Image (using #TmpD/ia)… Penn State researchers have developed new ultrathin metal electrodes allowing the creation of semitransparent perovskite solar cells that are highly efficient and can be coupled with traditional silicon cells to greatly boost the performance of both devices. The research represents a step toward developing completely transparent solar cells. Kai Wang, assistant research professor of […]

Inspired by nature, Pacific Northwest National Laboratory researchers have created a novel material capable of capturing light energy. The new material provides a highly efficient artificial light-harvesting system with potential applications in photovoltaics and bioimaging. The research provides a foundation for overcoming the difficult challenges involved in the creation of hierarchical functional organic-inorganic hybrid materials. […]
