Abstract

Concentrating Photovoltaics (CPV) represents an emerging market at its early stage for terrestrial application with large growth expectation and considerable research activity on new cells production has been conducting recently. As response to a fast growing demand for traceable and independent measurements on CPV cells and systems the European Solar Test Installation (ESTI) has started a research program on indoor/outdoor device characterization. This paper focuses on the results of an intercomparison of procedures and experimental setup for concentrating c-Si cell characterization held at ESTI and at the UTTP FOTO Laboratory of ENEA. Current-voltage curves, short-circuit current and efficiency measurements have been performed at high intensities on three different setups: a recently developed 1500X pulsed solar simulator at ESTI and two modified solar simulators capable of achieving up to 250X concentration at ENEA. Reference c-Si cells equipped with neutral density filters of various optical densities have been used at ESTI for checking the linearity of cells under test at different concentration ratios. First results show the agreement within measurement uncertainties of the electrical parameters.
