Concentrating photovoltaics Technology (CPV)  has become a relevant technology for solar energy conversion. Especially under high concentration, the use of  cost-effective, high-efficiency multi-junction solar cells enable high system efficiencies and a competitive levelized cost of electricity in regions with a large fraction of direct irradiance. However, the development of this technology requires the utilization of specific indoor/outdoor characterization techniques that are not yet widely known. A review of current hot topics in indoor/outdoor CPV characterization in energy and performance testing will be presented and discussed during this short SOPHIA on line course.

The integration of Photovoltaic elements into the building, the so called ‚BIPV’ is even today - after the solar revolution has started off worldwide - a huge challenge.

BIPV might see a new era of success in the developing super mass markets for PV as solar energy will become the ‘largest source of electricity worldwide’

The webinar based on three presentations of 2nd SOPHIA BIPV workshop presents different point of views of an PV Technology Research association representative, an architect and a Researcher on Building Integrated PV topic, considering market situation, countries regulations, R&D and architecture features.

Crystallization is the  lengthy natural process of formation of highly ordered structure of atoms that is today  currently utilized in technology by artificially precipitating solid crystals from a solution, melt or gases to realize crystal structure.  The growth of silicon Crystals  is perhaps the the most important technological topics  of the last decades—the "silicon era"  because It has been essential for the development of the electronic devices  and solar cells

CISSY_XPS_UPSX-rays interact with matter  through photoabsorption, Compton scattering, and Rayleigh scattering. The strength of these interactions depend on the energy of the X-rays and the elemental composition of the material  This SOPHIA webinar introduces two powerful spectroscopic tools to investigate solar cell surfaces and interfaces.

The efficiency of a solar cells is limited by defects and impurities Twidely present in commercial solar cells. The primary goal of materials research in photovoltaics is overcoming these lifetime-limiting defects, which include in multicrystalline solar cells: Grain boundaries, dislocations, and transition metals.

A lot of exciting ideas are followed by scientists and researchers all around the world on advanced photovoltaics searching for new solution in photoconversion, light trapping and novel collecting structures  the so called “field of dreams where the research concepts and technology require the PV researchers’s creativity,  patience and funding to prove or develop concepts”.

Focused ion beam (FIB), is a well established technique used particularly in the semiconductor industry, materials science and  biological field for specific analysis, deposition, and ablation of materials can   represent a very useful “ab inizio” technique to prove in very short time new  concepts on advanced photovoltaics  before making investment in their further development and searching for cost effective solution.
