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. 

Ted Sargent takes up the Gabor A. and Judith K. Somorjai Visiting Miller Professorship at Berkeley Fall 2017

Ted Sargent attended as an invited lecturer to the ACS-Tsinghua Symposium on Photonics on July 31st, 2017. He gave a lecture on “Solution-processed photodetectors, solar cells, and optical sources based on quantum dots and perovskites“. 

The symposium was held by Prof. Jie Bao, and his talk was from 10:25 to 11:00 am in Rohm 5-206 at Tsinghua University. More details can be found from the WeChat QR Code below:

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!
