Impurity-to-efficiency (I2E) simulator

I2E TCAD Simulator

Between 2009 and 2013, we developed a TCAD code that simulates the evolution of iron impurities in crystalline silicon solar cells during processing. This code has helped academics and industry improve performance, manufacturing throughput, and yield, via identifying optimal gettering time-temperature profiles.

I2E Sentaurus TCAD Add-on Scripts

With these scripts, we add the I2E models to Synopsys, Inc.’s Sentaurus TCAD. We use the Alagator Scripting Language to add the I2E to Sentaurus Process. The post-processing impurity and dopant distributions and their electrical effect can then be coupled with a solar cell device simulation in Sentaurus Device.

PV cost model

Our lab’s efforts to model cost and minimum sustainable price of PV manufacturing began in Spring 2011 as an internal exercise to define Lab R&D priorities. The effort was led by graduate student Douglas M. Powell, who conducted similar types of analyses at GE Wind before joining the PVLab. In Fall 2011, upon encouragement of the DOE SunShot Initiative, this effort evolved into a collaboration with Al Goodrich, Ted James, and Mike Woodhouse at the National Renewable Energy Laboratory. The outputs of this work have been translated into colloquial terms (The EconomistTechnology Review), and have helped inform the MIT Productivity in the Innovation Economy (PIE) study.

Our direct research outputs include:

  1. Cost model, freely available for download.
  2. Publications: (a) technology assessment; (b) minimum sustainable price assessment; (c) U.S.–China manufacturing MSP comparison. For the latter, please note the supporting online materials, which include updated Q3-2013 figures.
