Optimisation of novel vanadium based high temperature materials
M2.8 | Analysis of curved photovoltaic panels with a novel shell theory and a global-local approach
New designs of photovoltaic modules include curved light-weight structures composed from a carrying glass or polymer layer, silicon solar cells embedded in a soft polymeric encapsulant, and a back sheet usually made from polymer or glass. To assure reliable operation, efficient procedures for strength and deformation analysis are required.
The aim of this sub-project is to develop a novel layer-wise shell theory to analyse the global mechanical behaviour of curved photovoltaic panels. The procedure used to formulate governing balance equations should be based on the already existing approach applied to flat photovoltaic modules. The theory should be utilised within a finite element code by means of a self-implemented, user-element subroutine. To study the strength of brittle silicon cells inside the laminate, a global-local procedure should be developed. Therefore, a three-dimensional unit cell with boundary conditions derived from the global deformation field is to be analysed.
