Earth-Moon dynamics from cyclostratigraphy reveals possible ocean tide resonance in the Mesoproterozoic era.

Cyclostratigraphy is an important observational window into the history of the Earth-Moon system. However, there is limited information from the Mesoproterozoic era (1.0 to 1.

[Research on spectral response of CdSe quantum dots dopted polymer solar cell].

In the present paper, bulk heterojunction polymer solar cells based on P3HT:PCBM and P3HT:PCBM:QDs active layer were fabricated and measured respectively. The experimental result showed that the addition of QDs can broaden the spectral response and enhance photoinduced electron transfer. The conversion efficiency of device with QDs is about 25% higher than that without QDs.
