The Institute of Electrical and Electronics Engineers (IEEE) has recognised Zachary Holman from Arizona State University for his significant contributions in advancing solar efficiency.

Holman was awarded the 2019 IEEE Stuart R. Wenham Young Professional Award, reports Compound Semiconductor.

The Young Professional Award was recently renamed in honour of the late Stuart Wenham, a photovoltaics research leader who made profound contributions to the field.

Holman commented: “My team has mapped out the technological and economic landscapes for these types of solar cells in publications that have served as guides to the community.”

Holman’s notable achievements include making new scientific developments and advancing performance to record efficiencies in solar cells based on silicon, CdTe, perovskites and III-V materials.

His most significant contributions have been to silicon-based tandem solar cells.

He has also invented a new type of four-terminal tandem solar module that uses a 'PVMirror' to avoid materials compatibility challenges of typical tandem solar cell structures.

Further developments

For CdTe solar cells, Holman collaborated with ASU Professor Yong-Hang Zhang to develop a new hole contact that broke the open-circuit voltage record by more than 100 millivolts.

Myles Steiner, Photovoltaic Specialists conference awards chair, echoed the praise of Holman's contributions in these areas and noted Holman's colleagues also believe his achievements are significant and impressive.

“Dr Holman was nominated for this year's award by two independent sets of colleagues, which really speaks to his breadth of experience and to the impact that he has already had in the PV community,” Steiner said.
