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!
