Construction of solar cell angular response measurement system

Author: Martin Bliss (CREST) Tejas Sherkar carried out his internship at CREST Loughborough University in early May until mid-July. The aim of his project was to continue the development and construction of solar cell angular response measurement system, to assess misalignment uncertainties in the calibration processes. This will enable the STAPP team to reduce the uncertainty […]

Electroluminescence measurements of PV devices and modules

Quality assessment of photovoltaic devices requires advanced measurements that allow a non-destructive assessment of modules to assess the impact of different environmental stresses. Electroluminescence (EL) measurements offer a fast and easy way of quickly pinpointing defects within solar cells, and modules. In its most basic form, it can be used to identify micro cracks and […]
