Nanotechnology Now - Press Release: A general approach to high-efficiency perovskite solar cells


Home > Press > A general approach to high-efficiency perovskite solar cells
Researchers from the Institute for Applied Physics (IAP) and the Center for Advancing Electronics Dresden (cfaed) at TU Dresden developed a general methodology for the reproducible fabrication of high efficiency perovskite solar cells. Their study has been published in the renowned journal Nature Communications.

Abstract:
Perovskites, a class of materials first reported in the early 19th century, were re-discovered in 2009 as a possible candidate for power generation via their use in solar cells. Since then, they have taken the photovoltaic (PV) research community by storm, reaching new record efficiencies at an unprecedented pace. This improvement has been so rapid that by 2021, barely more than a decade of research later, they are already achieving performance similar to conventional silicon devices. What makes perovskites especially promising is the manne ....

A single super photon made up of many thousands of individual light particles: About ten years ago, researchers at the University of Bonn produced such an extreme aggregate state for the first time and presented a completely new light source. The state is called optical Bose-Einstein condensate and has captivated many physicists ever since, because this exotic world of light particles is home to its very own physical phenomena. Researchers led by Prof. Dr. Martin Weitz, who discovered the super photon, and theoretical physicist Prof. Dr. Johann Kroha have returned from their latest expedition into the quantum world with a very special observation. They report of a new, previously unknown phase transition in the optical Bose-Einstein condensate. This is a so-called overdamped phase. The res ....

Dr. Garret FitzGerald Wants to Build Bridges


Keynote Speaker discusses the science of discovery. 
Dr. Garret FitzGerald, a.k.a. “Big G” as faculty and students sometimes call him according to a 2001 Penn Medicine article, is a humble man with a proclivity for speaking about his research in equal medical and metaphoric terms. He fell into medicine through “a series of accidents” he thinks, though his earnest quest for knowledge is anything but.
Born and bred in Graystones, Co. Wicklow, he went to high school at a time when specialization in either the arts or the sciences wasn’t required as it is now. His grandfather had been a professor of Greek, he says, “So I did Greek and Latin and French and German and English and Irish,” but also rounded out his linguistics with and math and physics. It’s clear his secondary school studies have stayed with him. ....
