  • Solution-processed solar cells

    Molecular ink formulations from non-toxic solvents allow for the deposition of world-record efficient thin film CuIn(S,Se)2 solar cells.  Uhl et al. Energy & Environmental Science, 2016, 9, 130.

  • Semi-transparent perovskite solar cells

    Large-bandgap perovskite solar cells with semi-transparent contact layers enable their use as top cells in tandem applications. Uhl et al. Journal of Materials Chemistry A, 2017, 5, 3214.

  • Tandem solar cell devices

    Chalcogenide- and perovskite-based tandem devices can be fabricated monolithically to improve the utilization of the solar spectrum with minimal added processing costs. Uhl et al., Advanced Energy Materials, 2018, 1801254.

Converting solar energy into clean electricity and fuels

The reduction of greenhouse gas emissions to mitigate climate change while meeting the growing global energy demand is one of the greatest challenges of our time. Renewable energy technologies, such as photovoltaics (PV), have been identified by the Intergovernmental Panel on Climate Change (IPCC) to play a leading role in the necessary transition away from fossil-combustion-based energy sources. However, hurdles for widespread implementation such as cost competitiveness and the inherent energy intermittency of solar energy must be overcome.

At the Laboratory for Solar Energy and Fuels (LSEF), we are interested in the development of functional materials and devices for photovoltaic and photoelectrochemical applications that can convert abundant solar energy into clean electricity or storable fuels. Employing solution-processing methods for thin film layers has the potential to bring down cost and allow for the sustainable growth of renewable energy technologies.
