Fundamental understanding of IR reflection from heavily doped polycrystalline silicon

太阳能电池是绿色革命的重要组成部分，因为它们在不消耗化石燃料的情况下将阳光转化为电能。在各种光伏技术中，多晶太阳能电池以90%以上的市场份额占据主导地位。由于太阳能电池的面积要求很大，光伏电池的制造产能非常高，通常每小时运行近2500个电池。在如此高的吞吐量下，在线测量很困难，而且大多数测量都是离线完成的。我们已经获得了一些有趣的初步结果，这可能是一种在大容量太阳能电池制造中进行在线、非接触测量的方法。在这个项目中，我们建议获取更深入的数据，使我们能够了解我们的结果，并确定这项技术是否适用于光伏行业。如果成功，这个项目可能会导致CRD的应用。

Solar cells are an important part of the green revolution since they turn sunlight into electricity without consuming fossil fuels. Amongst the various photovoltaic (PV) technologies, polycrystalline solar cells dominate the market with greater than 90% market share. Due to the large area requirements for solar cells, PV cells manufacturing is very high throughput, typically running at almost 2500 cells per hour. At these high throughput rates inline metrology is difficult and most metrology is done offline. We have obtained some interesting preliminary results that there a possible method to do inline, non-contact metrology in high volume solar cell manufacuring. In this project we propose obtain more in-depth data that will permit us to understand our results and determine if this technique is viable for the PV industry. If successful this project will may lead to a CRD application.
