New breakthrough in battery charging technology

Date:
    April 24, 2017
Source:
    Ulsan National Institute of Science and Technology(UNIST)
Summary:
    A new study has introduced a new battery charging technology that uses light to charge batteries. This newly-developed power source is designed to work under sunlight and indoor lighting, allowing users to power their portable electronics anywhere with access to light. In addition, the new device could power electric devices even in the absence of light.

photo-electric conversion/storage efficiency of 7.61%

Less than 8% efficiency is something to brag about?

Multiple PV technologies now exceed 40%, Li Battery efficiencies exceed 90%.

Gubmit subsidies to Tesla are a testament that it is more than desperation, it's a left wing conspiracy.

It's not bad, actually, for what appears to be cheap, thin-film photocells.  The advertised charge rate (as opposed to the actual rate) seems quite useful, though that's when it's in sunlight rather than indoor lighting.
