Abstract：

In this talk, I will briefly talk about my research during my 21-year tenure career at Los Alamos National Laboratory. I will briefly summarize recent progress in energy research and the potential to move to commercial market. For the first part of my talk, I will focus on our most recent journey on the development of novel nanogrpahenes for highly efficient lithium ion batteries.  
Tradition graphene anodes in lithium ion batteries (LIBs) suffer from significant performance loss due to the restacking of graphene layers. In our lab, we have synthesized a series of 2D and 3D nanographenes with various functional groups attached to the edge of the nanographene basil planes. Among other potential application, these high-surface area nanographenes have an excellent cyclic durability and a much enhanced charge capacity as novel anode materials for LIBs. Moreover, theoretical charge capacity of these nanographenes exceeds 2000 mAh/g due to an increased edge to surface ratio and oxygen containing functional groups.

Recent discovery of hybrid perovskites such as CH3NH3PbX3 (X = Cl, Br, I) for photovoltaic devices has revealed very high PCE exceeding 20% and extraordinary potential of these materials for clean sustainable energy technologies. In the second part of my talk, I will discuss our recent progress in fabricating highly efficient solar cells based on hot casting hybrid perovskite films. These hot casting films comprised of large grain perovskite with grain size up to 1-2 mm and a homogeneity in the photophysical properties throughout the thin films.  Such homogeneity is far more superior than conventional precursor routes. I will further discuss our most recent efforts in using hybrid perovskite single crystal powders to fabricate solar cells.  Our results suggest possible avenues in addressing the stability concerns of hybrid perovskite solar cell devices.
