Solar cells are photovoltaic devices that convert light to electricity. During the photoelectric conversion process, a photovoltaic device internally undergoes multiple charge-carrier dynamics processes. These internal charge-carrier processes intrinsically dominate the performance of a photovoltaic device itself.

Over the past decade or so, researchers worldwide have developed increasingly advanced techniques to enable robot navigation in a variety of environments, including on land, in the air, underwater or on particularly rough terrains. To be effective, these techniques should allow robots to move around in their surroundings both safely and efficiently, saving as much…
Documents that express an opinion abound, especially in the so-called web 2.0 era of social media and social networking. Jae-Young Chang of the Department of Computer Engineering at Hansung University, in Seoul, South Korea, suggests that there is a need to find ways to summarize their contents for a wide range of applications.

Now more than ever before, the stakes are getting higher in professional gaming. E-sports should be taken seriously as both an occupation and a form of leisure. Riot Games, the developers of desktop juggernaut League of Legends, is even taking the game into Monday Night Football territory with its own weekday broadcast of the game’s…
As GPU architectures have become the standard for scientific computing, application teams have had to retrofit their scientific codes to run on new systems. Even teams with codes that have been re-engineered for GPUs must continually adapt them for new architectures.

Photovoltaic solar cells are a promising alternative to fossil fuels, but they need to be a lot more efficient before they can go into widespread use. Scientists have pushed current supercomputing power to the limit looking for that improved efficiency, but the arrival of exascale computing within the next few years will allow them to…
Academic researchers and others have long struggled with making data visualizations accessible to people who are blind. One technological approach has been 3-D printing tactile representations of data, in the form of raised bar graphs and line charts. But, often, the intended users have little say in the actual design process, and the end result…
The last of Apple’s 42 stores in China reopened Friday, as the country slowly goes back to work following weeks of quarantine that forced the closure of businesses. Read More https://techxplore.com/news/2020-03-apple-china-reopen.html Views: 0
