The formula of collection efficiency

18 02 2013

There is a short formula going around in the literature of dye-sensitized solar cells since long time ago, that relates collection efficiency to small perturbation time constant (lifetime and diffusion time). This formula looked strange to some people but it was widely used. Now Luca Bertolucci and co. have shown that this formula is not correct, it is not even a reasonable approximation

Dye solar cell impedance analysis with ISTest on your desktop

18 02 2013

New feature of ISTpro: Use it on your own computer.

ISTpro program by ISTest is a popular online tool for treating impedance spectroscopy data of dye-sensitized solar cells. ISTpro allows you to evaluate the performance of a set of DSC by analysis of chemical capacitance and recombination resistance plots vs. voltage, and to visualize additional features such as the internal voltage and efficiency, using the standard analysis protocols developed by Bisquert, Fabregat-Santiago and co., that have become universally adopted.

Now ISTPro runs in your computer.

Please download the desktop application and evaluate the use. If you do frequent analysis of DSCs you will find this tool invaluable for analysis and publication of your results.

Call for HOPV 13 in Seville

4 02 2013

Solar energy has an enormous potential for satisfying the future global energy demand. Hybrid and organic solar cells are making rapid advances in terms of efficiency, lifetime, and technology and have a true promise to become an important source of renewable energy. In addition, they present fascinating opportunities for scientific research and technological development. The main topics of this conference are the development, function and modeling of materials and devices for hybrid and organic solar cells, including dye-sensitized solar cells, polymer-fullerene solar cells, small molecule organic solar cells, and other ‘excitonic’ solar cell technologies, including hybrid organic-inorganic and nanostructured devices. Building upon success of the previous HOPV conferences, the HOPV 2013 conference will provide a excellent opportunity for scientists and engineers around the world for discussions of the latest developments in hybrid and organic photovoltaics. The conference will be led by world leading invited speakers covering a broad range of the latest scientific advances in morning plenary sessions. The conference encourages presentation of oral as well as poster contributions from scientists from all over the world, which will be presented in two parallel sessions running in the afternoons. Just submit your abstracts before the deadline, which is strict. Special attention is given to the poster contributions.
