If you try to search for “PSO” abbreviation in wiki you may find Pacific Symphony Orchestra or Phase-shift oscillator. However, my project at HZB is about neither music nor electricity, but mathematics. For almost a month here I have been working on an algorithm called Particle Swarm Optimization method and I would like you to have some impression of it.  Optimization Actually, the definition of optimization problem is quite simple. One has a function of n-variables f(x1, …, xn) and seeks to find such values of variables that give minimum to the function. However, the solution is not that simple, because in general you cannotRead More →

Why it’s important? Development of photovoltaic and other energy materials requires a lot of experiments and comprehensive processing of data is vital for successful research in this fields.  Unfortunately, sometimes measurement systems software couldn’t provide all necessary features, e.g. combining data from different samples, excluding inaccurate data, etc. That’s why we are currently developing complex data analysis program for state-of-the-art Hall Measurement system. Program itself is complex project in Python high-level programming language with a lot of different plotting and calculation options, such as calculating charge carrier concentration, mobility and many other parameters. It’s also possible to analyze AC field measurements, which is useful forRead More →
