Promising strategies for durable perovskite solar cells

(American Institute of Physics) Perovskite materials are increasingly popular as the active layer in solar cells, but internal forces in these materials cause distortions in their crystal structures, reducing symmetry and contributing to their intrinsic instability. Researchers at Soochow University examined the mechanisms at play, as well as several degradation factors that influence the performance of perovskite photovoltaics. In APL Materials, they clarified the factors influencing the degradation and they summarized some feasible approaches for durable perovskite photovoltaics.

Material properties for longer-lasting, more efficient solar cells

Researchers are helping to understand the fundamental processes in a material known as perovskites, work that could lead to more efficient solar cells that also do a better job of resisting degradation.

Powering the future: New insights into how alkali-metal doped flexible solar cells work

A group of scientists has discovered that the amount of alkali metal introduced into crystals of flexible thin-film solar cells influences the path that charge carriers take to traverse between electrodes, thereby affecting the light-to-electricity conversion efficiency of the solar cell. Given the immense application potential that such solar cells have today, this finding could be key to ushering in a green future.

UCF researcher is working to extend battery life in smartphones, electric cars

(University of Central Florida) A University of Central Florida researcher is working to make portable devices and electric vehicles stay charged longer by extending the life of the rechargeable lithium-ion batteries powering them.He is doing this by making the batteries more efficient, with some of his latest work focusing on keeping the anode from falling apart over time. The new technique is detailed in the journal Advanced Materials.

Mathias Cormann wants to be a chameleon on climate change when we’ve got a bin fire instead of a plan | Katharine Murphy

The window for attaining net zero emissions by 2050 and holding temperature increases to safe levels is “rapidly closing”. Evidence is mounting that the world is closer to abrupt and irreversible changes, “so-called tipping points”, than previously thought. Without further…

Biden’s Slow-Motion Plan To Destroy America’s Energy Industry

President Trump had several good moments in the final debate, as Andrea Widburg noted in her excellent curation here. In my own view, the standout moment came last, when Trump just drew out Joe Biden on energy, first on fracking, and then…

A new technique predicts how earthquakes would affect a city’s hospitals

An international research team has developed a methodology to help disaster preparedness officials in large cities make contingency plans on a region-wide basis to make sure that emergency responders can get patients to the hospital facilities that are likeliest to remain in commission after a quake.
