Laser-powered-drones may beat endurance hurdles

Hmm. Drones that can be recharged by a laser. So how long could they fly before having to land? How about "never mind"? We can look forward to seeing this idea in action. New Scientist had a story on September 3 that the ...

Ultrathin solar cells promise improved satellite performance

Most space satellites are powered by photovoltaic cells that convert sunlight to electricity. Exposure to certain types of radiation present in orbit can damage the devices, degrading their performance and limiting their ...

Promising strategies for durable perovskite solar cells

Perovskite materials are becoming increasingly popular as the active layer in solar cells. Internal forces in these materials cause distortions in their crystal structures, reducing symmetry and contributing to their intrinsic ...

Photovoltaic cell

A photovoltaic cell is a type of Photoelectric cell that uses the photovoltaic effect to generate electrical energy using the potential difference that arises between materials when the surface of the cell is exposed to electromagnetic radiation.

A photovoltaic cell is commonly used for detecting radiation (for example infrared detectors) or measurement of light intensity (for example in measuiring optical density) and chemical processes (for example Spectrophotometry) and for conversion of light to energy in solar cells.
