During the past few years a great variety of multi-junction solar cells has been developed with the aim of a further increase in efficiency beyond the limits of single junction devices. To...
Progress in the measurement of multi-junction devices at ISE (1991)
Bücher, K., Heidler, K., Müller-Bierl, B., Schönecker, A.
The ISE calibration laboratory is extending its facilities to measure multi-junction devices. In this paper we discuss a new reference cell method with software pre-selection of the simulator setting...
In most set-ups used to measure the spectral response of large area solar cells, it is not very easy to get uniform monochromatic and bias illumination over the total area of the solar cell, so...
Comparison of dark and light I-V curves of solar cells (1991)
Measurements of I-V-curves of several solar cells at different temperatures and illuminations were made. The results of transferring the fit parameters of the dark measurements to light I-V curves at...
Bücher, K., Heidler, K., Kleiß, G., Raicu, A.
The realistic reporting conditions (RRC) efficiency gives a site-dependent characterisation for solar cells, accounting for differences due to the variability of specific meteorological conditions...
Solarzellenparameter des 2-Dioden-Modells in Hell- und Dunkelkennlinien (1990)
Measurements of I-V-curves of several solar cells at different temperatures and illuminations were made. The results of transferring the fit parameters of the dark measurements to light I-V curves at...
Bücher, K., Heidler, K., Raicu, A.
As the assessment of solar cells for standard reporting conditions (SRC) (1000 W/qm, 25 degree C, AMI.5 reference spectrum) can be misleading when used for optimising solar cell design and PV plant...
