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（PV）技术中，多晶太阳能电池以超过90%的市场份额占据主导地位。由于太阳能电池的大面积需求，光伏电池的制造是非常高的吞吐量，通常每小时运行近2500个电池。在这些高吞吐率下，在线计量是困难的，大多数计量是离线完成的。我们已经获得了一些有趣的初步结果，有一种可能的方法来做在线，非接触式计量在大批量太阳能电池的制造。在这个项目中，我们建议获得更深入的数据，这将使我们能够理解我们的结果，并确定这项技术是否适用于光伏产业。如果成功，这个项目可能会导致CRD申请。

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.
