A Helmholtz-Zentrum Berlin für Materialien und Energie team has succeeded in producing inorganic perovskite thin films at moderate temperatures using co-evaporation – making post-tempering at high temperatures unnecessary. The process makes it much easier to produce thin-film solar cells from this material. In comparison to metal-organic hybrid perovskites, inorganic perovskites are more thermally stable. The […]

University of Maryland researchers have demonstrated a successful prototype of one critical component for affordable small-scale desalination: an inexpensive solar evaporator, made of wood. About a billion people around the world lack access to safe drinking water. Desalinating salty water into drinkable water can help to fill this dangerous gap. But traditional desalination systems are […]

A Boston College team of researchers has developed an alternative means using a unique semi-metal that intrinsically generates direct current through the nonlinear mixing of the waves of light. Typically, light is converted to electricity by chemically altering a semiconductor to have a built-in electric field. The recently discovered Weyl semimetal delivers the largest intrinsic […]

Kanazawa University researchers have documented a new method for controlling the orientation of conducting molecules in organic solar cells that results in the enhanced light adsorption and performance of the cells. Solar cells are an alternate source of energy. A subtype of these, organic solar cells, make use of organic polymers inside the cell. Using […]

Scientists from the Energy Materials and Surface Sciences Unit at the Okinawa Institute of Science and Technology Graduate University (OIST) believe they’ve found a winning formula in a new method to fabricate low-cost high-efficiency solar cells. Professor Yabing Qi and his team from OIST in collaboration with Professor Shengzhong Liu from Shaanxi Normal University, China, […]
