In the paper, the team reports the overall electrical - to - chemical power conversion efficiency of the system at 64 per cent. (sciencedaily.com)
The best light - to - energy conversion efficiency we've reached so far is 1 %, which is well below the usual 10 - 15 % efficiency of commercial silicon solar cells. (treehugger.com)
The composite material leads to a power conversion efficiency of up to 4.2 %, which is a record value for this class of materials. (sciencedaily.com)
