项目摘要
In this research project, we will develop two complementary techniques for studying semiconductor materials with direct band gaps. This will lead to an improved understanding of processes that limit the efficiency of solar cell materials and may, in the long run, contribute to the development of better solar cells with higher efficiency. The techniques are based on magnetic resonance (electron-spin and nuclear-spin magnetic resonance) but use optical pumping for enhancing the spin polarization and optical detection for increasing the sensitivity and allow spatial localization. The basic techniques for this project are established in the laboratories of both partners. For the present project, they will be extended and adapted for the planned measurements. To achieve spatial localization, we will use two complementary approaches: optical microscopy with independent beam paths for excitation and detection and spatial encoding via the Larmor frequency on the basis of pulsed magnetic field gradients. We envision that this project will contribute towards the long-term goal of economical and eco-friendly devices that harvest solar energy at the highest possible efficiency.
在这个研究项目中,我们将开发两种互补的技术来研究具有直接带隙的半导体材料。这将导致对限制太阳能电池材料效率的过程的更好理解,并且从长远来看,可能有助于开发效率更高的更好的太阳能电池。该技术以磁共振(电子自旋和核自旋磁共振)为基础,但使用光泵浦来增强自旋极化,使用光学检测来提高灵敏度并允许空间定位。该项目的基本技术是在双方的实验室中建立起来的。对于目前的项目,它们将被扩展并适应计划的测量。为了实现空间定位,我们将使用两种互补的方法:具有独立光束路径的光学显微镜进行激发和检测,以及基于脉冲磁场梯度的拉莫尔频率进行空间编码。我们设想这个项目将有助于实现经济和环保设备的长期目标,以尽可能高的效率收集太阳能。
