Abstract

The electrical ageing of photovoltaic modules during extended damp-heat tests at different stress levels is investigated for three types of crystalline silicon photovoltaic modules with different backsheets, encapsulants and cell types. Deploying different stress levels allows determination of an equivalent stress dose function, which is a first step towards a lifetime prediction of devices. The derived humidity dose is used to characterise the degradation of power as well as that of the solar cell's equivalent circuit parameters calculated from measured current–voltage characteristics. An application of this to the samples demonstrates different modes in the degradation and thus enables better understanding of the module's underlying ageing mechanisms. The analysis of changes in the solar cell equivalent circuit parameters identified the primary contributors to the power degradation and distinguished the potential ageing mechanism for each types of module investigated in this paper. © 2016 The Authors.

Abstract

Abstract: This study addresses the issue of poor intercomparability of measurements of organic photovoltaic (OPV) devices among different laboratories. We present a round robin performance testing of novel OPV devices among 16 laboratories, organized within the framework of European Research Infrastructure Project (SOPHIA) and European Energy Research Alliance (EERA). Three types of OPVs with different structures, dimensions and encapsulations are studied and compared with reference Si solar cells certified by accredited laboratories. The agreement of the measurements of these among different laboratories is analyzed by focusing on testing procedures, testing equipment and sample designs. A number of deviations and pitfalls are revealed and based on the analyses, a set of recommendations are suggested for improving the agreement among the measurements of such OPV technologies.

Abstract

Abstract: In the field of hybrid photovoltaic cell technology, the present work aims studying titanium dioxide layers with ordered nanostructure and poly-3-methylthiophene (P3MT) films in-situ electropolymerized onto them. Nanotube arrays were synthesized by anodization technique using a wide range of process conditions, and the dimensions and morphology of the obtained nanotubes were thoroughly analyzed. This study allowed tailoring the nanotube dimensions as requested by the final application. In this case, arrays with low thickness and large pore diameter, obtained in the acidic water based electrolyte, were selected to carry out further electropolymerization onto them. The nanotube pore diameter was identified as the dominant parameter influencing the P3MT layer thickness. The P3MT layers with the lowest thickness were obtained onto the less porous morphologies with low nanopore diameter values. [Copyright &y& Elsevier]
