Perovskite Solar Cells Have Intrinsic Instability Issues

Solar cell technology is now used by many industrial and government entities, but it is still prohibitively expensive for many individuals who would like to utilize it. There is a need for cheaper, more efficient solar cells than the traditional silicon solar cells so that more people may have access to this technology. One of [...]

A new technology capable of storing solar energy for up to several weeks has been developed by chemists at UCLA. The materials used for current residential rooftop solar panels can store energy from the sun for only a few microseconds at a time. The new approach was inspired by the way that plants generate energy [...]

Giant Quantum Dots could lead to Solar Panel Windows

Recent quantum dot research at Los Alamos National Laboratory could lead to windows that also act as solar panels. The work shows that the greater light emitting properties of quantum dots are applicable to solar energy, helping more efficiently harvest sunlight. Quantum dots, extremely small bits of semiconductor material, can be synthesized with almost atomic [...]

Energy is handled more efficiently in three-dimensional organic solar cells if the molecules are aligned face-on (shown in the illustration) instead of edge-on, according to a new study from North Carolina State University and UNC-Chapel Hill. The result may help design and manufacture more efficient and cost effective organic solar cells. In bulk heterojunction organic [...]
