Loading ...Yesterday “Nano Letters” released an article - “Photosensitization of ZnO Nanowires with CdSe Quantum Dots for Photovoltaic Devices” by Eray S. Aydil and et al. (DOI: 10.1021/nl070430o). I could not read the entire article because I am not a subscriber and don’t want to spend $25, but judging by the abstract the research team’s quantum-dot-sensitized nanowire solar cells were able to produce 1 to 2 mA/cm2 and open-circuit voltages of 0.5-0.6 V under simulated sunlight with 50-60% efficiency which is extremely impressive!

1If I remember, I’ll send it to you tomorrow. After all, I owe you one.
Thanks for pointing that out, though, since my summer project will be on similar devices.

2Ψ*Ψ,
Summer project on photovoltaic cells? Wow! When I was “shopping” for grad schools I visited the University of Maryland College Park, and in one of the research institutes they showed very cool solar panels made of the very thin, or as you say these days, nanolayers of molybdenum (if I remember correctly). They looked like rolls of flexible plastic that you could put practically anywhere and had higher efficiency than the conventional silicon-based solar panels.

3Well, my current projects revolve around new materials for organic solar cells, so it isn’t that much of a stretch. (Sorry about the paper! Today was busy. Email me and I will definitely remember for tomorrow.)
