Episode 16 – Sun & Surf

For our first episode of the summer on LASER: Let’s Agree Science & Engineering are Rad, we discuss our own Chris’ recently-accepted paper about inorganic ZnS window layers on organic solar cells.  These increase the efficiency, and help protect the cell from environmental damage.   We then talk about the NRL Press release describing long-chain hydrocarbon fuel (jet fuel) they have made by extracting CO2 and Hydrogen from seawater!

4:00 We’re all back from traveling for work and conferences, finals are done, and Chris just finished his qualifying exams, so we’re back to podcasting, even if we are a little rusty.

6:00 Our first paper is somewhing Chris just got accepted into Journal of Applied Physics, and it is titled “Efficient ZnS cathode layers for orgnaic photovoltaic applications via n-type doping.”

They are using an inorganic material, ZnS to replace the very sensitive organic cathode (top) layer in organic photovoltaics.  Since the organic components are very sensitive to temperature and air, an inorganic cathode can protect the bottom layers.

At the time we’re putting this episode out, the paper isn’t available online yet, but it will eventually be available at

32:30 We discuss the recent press release from NRL (  describing fuel made from CO2 and Hydrogen that was extracted from seawater.  There are a number of press articles about this: Discovery ( Business Insider ( and Inhabitat ( are a few.

38:00 Removing Co2 from ocean water *might* have a small local effect reducing ocean acidification, but because the end result is burning a hydrocarbon fuel, it will end up just going back into the atmosphere and back into the oceans.
