Regioselective functionalization of perylenes reduces voltage loss in organic solar cells

The power conversion efficiencies of organic solar cells (OSCs) based on blends of electron donor (D) and acceptor (A) semiconducting materials now exceed 16%. However, it is still lower than that of highly efficient inorganic SCs such as GaAs and… Read moreRegioselective functionalization of perylenes reduces voltage loss in organic solar cells

Solar Resource Compass improves solar irradiance data selection and estimates impacts of soiling and snow

DNV GL has launched a new online tool, Solar Resource Compass, that aggregates solar irradiance from many leading data providers to help users make more informed decisions about the data available and the variance between data sources. Solar Resource Compass… Read moreSolar Resource Compass improves solar irradiance data selection and estimates impacts of soiling and snow

Oblique electrostatic inject-deposited TiO2 film leads efficient perovskite solar cells

The need to efficiently harvest solar energy for a more sustainable future is increasingly becoming accepted across the globe. A new family of solar cells based on perovskites – materials with a particular crystal structure – is now competing with… Read moreOblique electrostatic inject-deposited TiO2 film leads efficient perovskite solar cells

Next generation of greenhouses may be fully solar powered

Many greenhouses could become energy neutral by using see-through solar panels to harvest energy – primarily from the wavelengths of light that plants don’t use for photosynthesis. Those are the findings of a new modeling study conducted by engineering, plant… Read moreNext generation of greenhouses may be fully solar powered

Simple, solar-powered water desalination

A completely passive solar-powered desalination system developed by researchers at MIT and in China could provide more than 1.5 gallons of fresh drinking water per hour for every square meter of solar collecting area. Such systems could potentially serve off-grid… Read moreSimple, solar-powered water desalination

CIGSe thin-film solar cells: EU Sharc25 project increases efficiency

Producing thin-film solar modules requires much less energy than conventional wafer-based Si PV modules, and therefore their energy payback time is much shorter. Chalcopyrite-structured compounds of copper, indium, gallium, and selenium (CIGSe) are an important class of materials for thin-film… Read moreCIGSe thin-film solar cells: EU Sharc25 project increases efficiency

Russian scientists propose a technology reducing the cost of high-efficiency solar cells

A group of St. Petersburg scientists has proposed and experimentally tested a technology for the fabrication of high-efficiency solar cells based on A3B5 semiconductors integrated on a silicon substrate, which in the future may increase the efficiency of the existing… Read moreRussian scientists propose a technology reducing the cost of high-efficiency solar cells

Researchers virtually ‘unwind’ lithium battery for the first time

An international team led by researchers at UCL has revealed new insights into the workings of a lithium battery by virtually “unrolling” its coil of electrode layers using an algorithm designed for papyrus scrolls. In a study published in Nature… Read moreResearchers virtually ‘unwind’ lithium battery for the first time

How iron carbenes store energy from sunlight – and why they aren’t better at it

Photosensitizers are molecules that absorb sunlight and pass that energy along to generate electricity or drive chemical reactions. They’re generally based on rare, expensive metals; so the discovery that iron carbenes, with plain old iron at their cores, can do… Read moreHow iron carbenes store energy from sunlight – and why they aren’t better at it
