Approaching the radiative efficiency limit with hybrid perovskite solar cells
Our recent 2018 Nature Photonics paper shows how surface passivation can allow record carrier lifetimes, and achieve over 97% of the theoretical quasi-Fermi-level splitting (voltage) measured in the archetypal perovskite, methylammonium lead triiodide. Congratulations to Dane and Ian for a great paper and fruitful collaboration. Nature Photonics volume 12, pages355–361 (2018) DOI: 10.1038/s41566-018-0154-z

Probing Ion Transport in Conjugated Polymers
Raj’s paper uses Electrochemical Strain Microscopy (ESM) to show that ion-uptake varies as a function of local structure in conjugated polymer films. It appeared only today in Nature Materials, along with a nice News and Views. By using multimodal scanning probe microscopy to reveal how local structure controls ion uptake in electrochemically active polymers the work opens the door to the design of new materials for organic bioelectronics, polymer-based battery electrolytes, and related applications. Polymers from our collaborators in the Luscombe Group made the study possible.

Quantum dots are semiconductor nanocrystals on the scale of a few nanometers, or several hundred atoms. At this size quantum effects dominate and the electrons are quantum confined to narrow energy levels determined by the size of the particle.
This means that the absorption wavelength the light can be fine-tuned and that quantum dots can be used to adjust the bandgap of the materials they are associated with. Quantum dots being explored for use in photovoltaics and in signal processing.
This shows professional laboratory procedures for synthesizing quantum dots.

Nanoprisms are used to adjust color of chemical systems they are mixed with for example in organic photovoltaic devices. The size of the nanoprisms determines the absorption wavelength. This shows the synthesis of silver nanocrystals at a professional chemistry laboratory at University of Washington. This procedure should not be attempted without laboratory safety provisions.

David Ginger and Alvin Kwiram have partnered to study renewable energy sources. Currently, the population gets 80 percent of energy from fossil fuels and solar energy is not affordable for all. The duo are working with colleagues in engineering in hopes of finding an alternative. It is challenging to summarize 150 years of achievement but one thing is clear -- all future discoveries will be fueled through research.
