The book is devoted to optical modeling and simulation of thin-film solar cells and PV modules. It was designed as a monograph and a comprehensive guide for performing optical modeling and simulations, giving insights into examples of existing optical models, demonstrating the applicability of optical modeling and pointing out concrete directions and solutions for improving the devices under scope. We have incorporated practical examples for using simulations with the developed models so that readers can better understand and develop their own models as well as innovative concepts in light management in thin-film photovoltaic devices. We discuss different approaches of one-, two- and three-dimensional optical modeling. Concepts and approaches presented in the book are in line with opportunities and challenges in thin-film PVs, but also optoelectronics and photonics.

A new model of non-conformal layer growth of layers in thin-film solar cells is presented. The model utilizes linear combination of two principles of growth (conformal and isotropic) to accurately predict the morphology of internal interfaces within solar cells. Additionally this model enables detection of substrate textures leading to formation of defective regions in absorber layers and their omission. Use of this model in optical simulations increases the validity and accuracy of results of substrate texture optimisation.

Outdoor stability testing of ionic liquid based dye sensitized solar cells under short circuit (SC) and open circuit (OC) modes has been followed using electroluminescence (EL) and transmission imaging. The EL imaging demonstrated that ageing, regardless the operating mode, is associated with the growth of the EL inactive areas that appear as black spots or defects, which we associate with the formation of iodine species in the electrolyte that have been captured under confocal microscope. The stability testing demonstrates that growth of the defects is more pronounced for cells operated in SC mode, which primarily reduces stability of Jsc.
