Black Silicon Made from Copper Gets Even Cheaper, Impacts Solar Cells

Ari Luis — Sun, 07 Sep 2014 08:33:26 +0000

In several articles in the past, we featured black silicon– a technology that can be used to tweak the current solar cell production process and come up with more efficient solar cells. Although the silicon isn’t really black, it looks dark because very, very little light gets reflected – less than 5%, in fact. This […]

Aalto University scientists have achieved an improvement in light absorption and surface passivation of silicon nanostructures after applying an atomic layer coating. This finding may advance high sensitivity light response devices such as high efficiency solar cells. Researchers detailed their findings in the January issue of Journal of Photovoltaics. Surface passivation is improved by utilizing […]

Imagine we could also harvest solar power while it’s cloudy outside, and those clouds won’t make much of a difference. That could be possible due to a new generation of perfectly-black solar cells, the blackest possible, which can actually trap 99.7 percent of the incoming light. Natcore Technology, the exclusive licensee of Rice University black […]

Harvard`s Black Silicon: 100 to 500 Times More Powerful Than Old Solar Cells

Ovidiu Sandru — Mon, 13 Oct 2008 12:26:30 +0000

Kept in secret until yesterday, a newly appeared company, named SiOnyx, unveils an invention of some Harvard researchers, that is going to revolutionize the whole industry. Harvard has been studying their "black silicon" for almost ten years, but nothing has come out of their lab, due to internal policies regarding the output of their discoveries to commercial companies.
