It was believed that efficient operation of organic solar cells requires a large driving force, which limits the efficiency of organic solar cells. Now, a large group of researchers led by Feng Gao, lecturer at IFM at LiU, He Yan at the Hong Kong University of Science and Technology, and Kenan Gundogdu at the North Carolina State University have developed efficient organic solar cells with very low driving force.

This implies that the intrinsic limitations of organic solar cells are no greater than those of other photovoltaic technologies, bringing them a step closer to commercialisation.

Scientists at Oxford University have developed a solvent system with reduced toxicity that can be used in the manufacture of perovskite solar cells, clearing one of the barriers to the commercialisation of a technology that promises to revolutionise the solar industry.

Perovskites – a family of materials with the crystal structure of calcium titanate – have been described as a 'wonder material' and shown to be almost as efficient as silicon in harnessing solar energy, as well as being significantly cheaper to produce.

Berkeley Lab desarrolla un mejor método de vigilancia del medio ambiente mediante el PhyloChip, que encuentra resultados sorprendentes en la cuenca del Río Ruso. Cuando la agencia local de manejo de agua cierra tu playa favorita debido a la calidad del agua insalubre, ¿Qué grado de confiabilidad tienen las pruebas en las que se basan sus decisiones? 

A University of Cincinnati scientist has engineered an environmentally friendly technology to zap outbreak-causing viruses and bacteria from public drinking water.

Environmental and biomedical engineer David Wendell, an associate professor in UC’s College of Engineering and Applied Science, developed a protein-based photocatalyst that uses light to generate hydrogen peroxide to eliminate E. coli, Listeria, and potentially protozoa like giardia and cryptosporidium.

New research from North Carolina State University finds that urban warming reduces growth and photosynthesis in city trees. The researchers found that insect pests are part of the problem, but that heat itself plays a more significant role.
