Welcome to DFCTI

The Department of Computational Physics and Information Technologies (DFCTI) plays a key role within the research strategy of the Horia Hulubei National Institute for R&D in Physics and Nuclear Engineering (IFIN-HH).

DFCTI's staff conducts inter- and multidisciplinary research in areas such as strongly correlated systems, nuclear and subnuclear phenomena, condensed matter and biomolecular systems, using computational methods. Besides, the department provides resources and services of high performance computing (HPC) as well as high throughput computing (HTC) and cloud computing for the support of large scale international collaborations and projects, like the Worldwide LHC Computing Grid (WLCG) and Extreme Light Infrastructure - Nuclear Physics (ELI-NP).

The technical expertise of the staff includes HPC and grid technologies, algorithm programming and optimization, distributed data access and management, advanced networking, cluster architectures and optimization, parallel computing, symbolic computing, molecular dynamics.

DFCTI coordinates the National Grid Infrastructure (NGI-RO) - which represents Romania in EGI, the Romanian LHC Grid Federation (RO-LCG), and the National Grid for Physics Research and Related Fields (GriNFiC). It also supports the Romanian Association for Promotion of Advanced Computational Methods in Scientific Research (ARCAS).


You are invited to attend "Bias induced normal and inverted hysteresis in perovskite solar cells" seminar, presented by Dr. Alexandru Nemnes, on 24.04.2017, 10:00, at the National Physics Library.

We report normal and inverted hysteresis in the J-V characteristics occurring for the same device structure, the behavior strictly depending on the pre-poling bias [1]. Normal hysteresis typically appears at pre-poling biases larger than the open circuit bias, while pronounced inverted hysteresis occurs for negative bias pre-poling. The measured J-V characteristics are explained quantitatively by the dynamic electrical model (DEM) [2]. Introducing a three step measurement protocol, which includes stabilization, pre-poling and measurement, we put forward the difficulties and possible solutions for a correct PCE evaluation.    References: [1] G.A Nemnes et al., arXiv:1704.03300 (2017); [2] G.A Nemnes et al., Sol.
