University of Cambridge researchers have identified a key mechanism responsible for the lower efficiencies of organic solar cells and shown a way that this hurdle might be overcome. The international group of researchers, led by the University of Cambridge, identified a loss pathway in organic solar cells which makes them less efficient than silicon-based cells […]

Martin-Luther-Universität Halle-Wittenberg found 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. Researchers achieved this by creating crystalline layers of barium titanate, strontium titanate and calcium titanate which they alternately placed on top of one another. These findings could significantly […]

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 […]
