Thomas Huld,Gabi Friesen,Artur Skoczek,Robert P. Kenny,Tony Sample,Michael Field,Ewan D. Dunlop +6 more
TL;DR: In this paper, a model for the performance of generic crystalline silicon photovoltaic (PV) modules is proposed, which represents the output power of the module as a function of module temperature and inplane irradiance, with a number of coefficients to be determined by fitting to measured performance data from indoor or outdoor measurements.
Proceedings ArticleDOI
Overview of Temperature Coefficients of Different Thin Film Photovoltaic Technologies
Energy rating of PV modules: comparison of methods and approach
TL;DR: In this article, a power matrix or performance surface as a function of irradiance and ambient temperature P(Gi; Ta) is linked to a climatic condition occurrence matrix N(Gi, Ta) for a particular location.
Journal ArticleDOI

Gabi Friesen,H.A. Ossenbrink +1 more
TL;DR: In this article, the photo-current-response measurement (PCR) method was used for the investigation of capacitance effects and the diffusion capacitance as experimental results achieved by the PCR-method.
