ABSTRACT:
The talk will be a brief update on recent developments in the solar simulation software QssCell, as well as an introduction to amorphous/crystalline silicon heterojunctions for the uninitiated. QssCell now allows for the iterative simulation of cell parameters as a function of two input variables, facilitating a more detailed analysis of how the ultimate device performance depends on defects and other factors. As a test case, the advantages and disadvantages of heterojunction cell structures on silicon will be explored, leading into recent progress on sputtered amorphous silicon and planned studies on sputtered heterojunction structures.
BIO:
With a background in the analytical and numerical studies of optics and carrier dynamics in semiconductors, Stuart has recently made the transition from electro-optics and transient photoconductivity in Terahertz Time-Domain Spectroscopy to photovoltaic engineering.

In the field of photovoltaics, he has interests in the surface passivation of crystalline silicon with amorphous silicon, a-Si/c-Si heterojunctions, sputtered deposition of surface films, and the modelling of optical, electrical and material properties of photovoltaic devices and materials.
