RELIABILITY OF PHOTOVOLTAIC DEVICES

 

A crucial challenge in the further development and towards commercialisation of novel generation solar cells is the increase of the stability and lifetime.  In order to tailor for instance the synthesis of new robust organic or inorganic semiconductors and to develop new concepts for solar cells with increased stability, it is essential to understand the underlying degradation mechanisms.

A powerful approach for the study of these mechanisms is by combining in-situ monitoring techniques and physico-chemical analytical techniques.

Key environmental parameters related to stability and degradation of solar cells are temperature, humidity and light. The specific approach followed at IMO-IMOMEC is to investigate the influence of environmental parameters (temperature, humidity, light,..) on both the photovoltaic parameters (IV-characterisation) and on materials properties such as the bulk morphology (TEM/SPM/Optical & Fluorescent Microscopy).

Appropriate in-situ accelerated ageing systems are available to determine acceleration factors for lifetime prediction
