Queen Mary University of London researchers have developed a new process for producing stable perovskite materials to create more efficient solar cells. Currently crystalline silicon is the most widely used material for solar cells. However, over the last decade, perovskite solar cells, made from metal halide perovskite materials, have shown promise to make cheaper, and […]

Imperial College London researchers have incorporated phosphorene nanoribbons into new types of solar cells, dramatically improving their efficiency. Phosphorene nanoribbons (PNRs) are ribbon-like strands of the 2D material phosphorus, which, similar to graphene, are made of single-atom-thick layers of atoms. PNRs were first produced in 2019, and hundreds of theoretical studies have predicted how their […]

Aalto University scientists have taken a close look at how lignocellulose – or plant biomass such as wood – can be used for optical applications, potentially replacing commonly used materials like sand and plastics. A digital, urbanized world consumes huge amounts of raw materials that could hardly be called environmentally friendly. One promising solution may […]

Scientists at Martin-Luther-Universit├Ąt 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 […]
