Ted Sargent will be giving an invited seminar at the UC Berkeley Department of Electrical Engineering and Computer Sciences on September 29th, 1pm in 521 Cory (Hogan Room) Cory Hall. 

Colloidal quantum dots, perovskite semiconductors, and their combinations, have proven the potential of liquid-processed semiconductor materials in the field of optoelectronics. Ted present advances in: 

• Sensitive photodetectors and image sensors;
• Solar photovoltaics;
• Optical sources, both LEDs and lasers; and
• Electrocatalysts for CO2 reduction and energy storage;

based on recent advances in materials chemistry combined with photophysics of these materials and improved device optoelectronic models.

Recent research from a collaboration between the Sargent and Peidong Yang labs was featured on the Berkeley Labs news. This work, performed by lead Dr. Michael B. Ross, was published in the Journal of American Chemical Society.

Ted Sargent will be giving a special seminar at Stanford University Sept. 7th, 2017 – Packard Rm 101, 4pm. The abstract for the talk is below:

Rapid progress in the cost-effective conversion of solar and wind energy into electrical power brings about a new challenge: the massive (seasonal-scale) storage of energy. We focus on using computational materials science, spectroscopies including ultrafast and synchrotron, and advances in materials chemistry, to create new catalysts for CO2 reduction and oxygen evolution.

I will discuss recent advances including new high-activity OER catalysts and lowoverpotential CO2 reduction catalysts based on field-induced reagent concentration. I will also touch on related materials design problems in optoelectronics, including the design of organic-inorganic materials for photon-to-electron and electron-to-photon conversion.

The Sargent Group Wechat is now up and running!

The account will update the most recent research published from our group, and will also share our groups life, to a broader audience.

On June 8, 2017, Olivier Ouellette, Mathieu Lempen, Marc Lejay, and Emma Howard welcomed a distinguished delegation of visiting scholars from Brown PS French Immersion Class Grade 4-5.

Ph.D Candidate Olivier Oulette recently gave an invited lecture to the grade 4-5 class at Brown Public School in Toronto. Olivier spoke about solar cells and quantum dots to a group of bring young future scientists!
