Michael manages the Aixtron MOCVD reactor, driving the growth efforts for the various research projects associated with the Hubbard group. Projects of specific interest are the development of InAlAsSb on InP as a host material for quantum dots in an intermediate band solar cell, as well as the growth of a multi-junciton solar cell with subcells lattice matched to both GaSb and GaAs without the use of a buffer layer.
His PhD dissertation was related to the development of a nipi doping superlattice solar cell. The nipi solar cell is also a defect tolerant design which can be used for solar cells on low cost substrates, or with high volumes of nanostructures that can cause defects in the host material.

The primary focus of my research is development of new III-V materials for photovoltaics, specifically InAlAs and InAlAsSb. These types of materials are useful for high efficiency lattice-matched triple junction solar cells in space or under concentration on earth. I personally help with growth of these crystals at NASA and will run the new MOCVD reactor at RIT in addition to fabricating and testing devices. Additionally, I am working on a life-cycle assessment comparing the amount of energy it takes to make different high efficiency photovoltaic cells grown by MOCVD.

My research focuses on developing high efficiency III-V solar cells by incorporating light trapping techniques into the design of quantum dot enhanced single junction GaAs devices. Currently I am working on developing a procedure for Epitaxial Lift-off to be used in the fabrication of thin film solar cells at RIT. I am also optimizing a backside texturing that will ultimately confine photons within the absorbing regions of the thin film cavity.

PhD in Microsystems Engineering – Rochester Institute of Technology 2019
My research explores III-V growth on alternative substrates by analyzing the effects that polycrystallinity, surface roughness, and interfacial defects have on device performance.. I am currently investigating solar cell growth on polycrystalline GaAs and Ge substrates, as well as recrystallization techniques to obtain large-grain polycrystalline Ge substrates. The ultimate goal of my research is to grow III-V material on arbitrary, compliant substrates for lower cost, lightweight photovoltaics.

Working on improving Aluminum Induced Recrystallization techniques to create lower-cost III-V substrates with PhD Student Elisabeth McClure. Our approach involves branching off of previous work and varying some of the many parameters including time, temperature, pressure, etc. The device physics of solar cells is a big interest of mine and I’d like to handle patent law in the semiconductor field in the future!
Ph.D. Microsystems Engineering
Supported by NSF
Presently working on simulation and optical investigation of carrier dynamics in III/V quantum dot solar cells, which enables us to understand the device physics and improve the device performance. I am also interested in quantum well or nano-wire embedded diode structure for solar cell, LED and laser applications. When I graduate, I hope my dissertation sheds light on the realization of high efficiency intermediate band solar cell.
