Silicon teams up with perovskites to form tandem solar cells

March 24, 2015

Traditional solar cells with a single band gap utilize less than half the energy in the solar spectrum. We’re developing “tandem,” or vertically stacked, solar cells, which aim to convert a greater percentage of incident sunlight into electricity. Our focus is on foundational technology development, including proof-of-principle demonstrations of device architectures and manufacturing approaches, methods to overcome key […]

Impurity gettering TCAD software available for download

March 24, 2015

Ashley Morishige presents at the SiliconPV conference in Konstanz, Germany about the 2D and 3D gettering simulation tool she developed in collaboration with the company Synopsys, maker of Sentaurus Device. The Impurity-to-Efficiency Simulator for Sentaurus TCAD scripts and a short user manual are online from our lab’s website and PVLighthouse. http://pv.mit.edu/impurity-to-efficiency-i2e-simulator-for-sentaurus-tcad/http://www.pvlighthouse.com.au/simulation/linked/I2E/I2E.aspx
