This note presents a reinvestigation and revaluation of the quantum yield of 2AMP in 1 M H2SO4 using quinine bisulphate in 1 M H2SO4 as the reference standard with a modern spectrofluorometer.

Photoluminescence is proportional to the number of charge carriers in the perovskite and, therefore, is sensitive to charge transfer into adjacent layers. This makes photoluminescence-based techniques invaluable for investigating the performance of new extraction layers.

Using time-resolved X-ray photoemission spectroscopy, scientists are for the first time analysing at the femtosecond scale the processes in a model system for organic solar cells.

There are a number of advantages of Raman microspectroscopy, including its the ease of its application, as in many cases no or very little sample preparation is needed and the experiments are performed at atmospheric pressure.

15 Aug 2016

Using ultrafast spectroscopy, researchers from Lund University, Sweden, have successfully measured in detail the flow of solar energy, in and between different parts of a photosynthetic organism. The result is a first step in research that could ultimately contribute to the development of technologies that use solar energy far more efficiently than what is currently possible.

X-ray spectroscopy at BESSY II reveals inhomogenous distribution of chlorine in a special class of perovskite materials, which could help enhance efficiencies of perovskite thin film solar cells by controlled processing to optimise the chlorine distribution.
