Iris PV

the next evolution in photovoltaics


team:

Co-founders Colin Bailie, Ph.D. and Mike McGehee, professor, Stanford University.

Co-founders Colin Bailie, Ph.D. and Mike McGehee, professor, Stanford University.

Colin Bailie earned a PhD in materials science from Stanford University in Jan 2016 and is currently a postdoctoral researcher at Stanford. He holds a B.S in mechanical engineering from Texas A&M University. In his graduate work, he published seminal papers on perovskite tandems in both mechanically-stacked and monolithic architectures and filed patents that enable these architectures with his academic advisor, Michael McGehee.  For his graduate work and efforts towards starting a venture to commercialize this technology, Colin has won numerous awards, most recently being named to the Forbes 30 under 30 in Energy and to the inaugural Slavin fellowship.

Michael D. McGehee is a Professor in the Materials Science and Engineering Department and a Senior Fellow of the Precourt Institute for Energy.  His research interests are developing new materials for smart windows and solar cells.  He has taught courses on nanotechnology, nanocharacterization, organic semiconductors, polymer science and solar cells. He received his undergraduate degree in physics from Princeton University and his PhD degree in Materials Science from the University of California at Santa Barbara, where he did research on polymer lasers in the lab of Nobel Laureate Alan Heeger.  He won the 2007 Materials Research Society Outstanding Young Investigator Award.


technology:

Critical need: Improvements in the performance of solar panels are needed for solar power to become directly competitive with conventional sources of energy, especially as photovoltaic (PV) penetration grows.

Technology vision: By boosting the overall efficiency of conventional solar cells, Iris PV will open new markets for residential and commercial photovoltaics, dramatically accelerating adoption worldwide.

Current state-of-the-art: Current solar panels use a single absorber material, limiting the performance of the panel. Double-junction tandems overcome this limitation by utilizing sunlight more effectively.

Key innovation: Solution-processed metal-halide perovskites that are transparent to infrared light, stable, and low-cost.

Manufacturing challenges: Deposition and patterning of the perovskite at module scale with high yield and uniformity.

Competing technology: Iris PV’s solar panels must surpass, at minimum, the performance of standard solar panels using silicon, CdTe, or CIGS. There is a strong likelihood that others will also attempt to make tandem solar cell products.

First market hypothesis: Initial entry will be in markets where performance is valued at a premium.

Potential for impact: The cost and performance improvements expected by Iris PV’s technology will enable substantially higher PV penetration worldwide, potentially offsetting 3 Gigatons CO2eq per year. We will add large margins back to the income statements of PV companies and reinvigorate an increasingly choked industry.
