Optical simulations of bifacial PV cells and modules

Bifacial PV cells and modules convert light incident onto the front as well as the rear side. The ability to use light incoming from the rear side for the generation of electrical current enables bifacial modules to have higher...


Procedures and Setups for the Measurement of the temperature coefficient of photovoltaic devices

The temperature coefficients of a photovoltaic (PV) device are generally perceived as its percentage change of the electrical parameters (e.g. short circuit current ISC, open circuit voltage VOC, maximum power PMax, spectral...


Procedures and Setups for the Measurement of the linearity of photovoltaic devices

The linearity of a photovoltaic (PV) device is generally perceived as proportionality of the photocurrent and the irradiance. A deviation from linearity, i.e. the non-linearity of a PV-device can manifest itself as poor low-light...


Traditional and emerging solar modules, current situation, market overview and new trends for BIPV systems

The BIPV market in Europe is in a transition. The past decades of a slowly emerging BIPV market have been characterized by the original dominant value of BIPV: a building that communicates an image of sustainability and...


Procedures and Setups for the Measurement of Bifacial Solar Devices

The precise measurement of the illuminated current-voltage (IV) characteristics is of central importance for solar cell and module manufacturers. While the procedure for the measurement of conventional monofacial solar devices is...
