Book Description
Abstract: This review explores the current state of the art in spatially resolved characterization of mixed-halide perovskite solar cells. As the size of perovskite cells and modules continues to grow, quantification of the spatial distribution of key cell parameters will become increasingly valuable in predicting ultimate cell-level performance and tracking process homogeneity. Here, both high resolution microscopic approaches using scanning techniques and camera-based methods for full-area cell and/or module analysis are discussed. The value of this local data in predicting performance losses at the cell level is particularly emphasized. Measurable physical parameters sensitive to losses of voltage, current, fill factor, and efficiency are discussed together with selected experimental results. It is demonstrated that a combination of spatially resolved cell parameter mapping/imaging can be used to quantitatively discriminate various loss contributions at high resolution. The impact and control of inhomogeneities become particularly important when upscaling from small devices to large formats compatible with industrial mass production

Book Description
The book is devoted to the spatial characterization of solar cells and PV modules. It is written both as a monograph as well as a succinct guide for the state-of-the-art spatial characterization techniques and approaches. Amongst the approaches discussed are visual imaging, electro- and photo-luminescence imaging, thermography, and light beam induced mapping techniques. Emphasis is given on the luminescence image acquisition and interpretation due to its great potential. Characterization techniques are accompanied by simulation tools. The contents are aimed at a readership of students and senior researchers in R&D as well as engineers in industry who are newcomers to the spatial characterization of either solar cells or PV modules. The concepts and approaches presented herein are based on but not limited to case studies of real thin-film PV devices. Key features:  Review of spatially resolved characterization techniques and accompanying SPICE simulations in photovoltaics  Use of spatially resolved characterization techniques and their combinations for the identification of inhomogeneities in small area CdTe and dye-sensitized solar cells  Case studies of electroluminescence imaging of commercial PV modules (c-Si, CIGS, CdTe, a-Si, tandem and triple junction thin-film-Si) The contents are aimed at a readership of students and senior researchers in R&D as well as engineers in industry who are newcomers to the spatial characterization of either solar cells or PV modules.

Book Description
Abstract: This thesis discusses studies performed by the author at the Fraunhofer Institute for Solar Energy Systems, ISE. The presented work focuses on the characterization of hybrid organic-inorganic halide perovskite materials used for photovoltaic application. In an in situ study of the perovskite crystal formation, multiple stages are identified. Taking advantage of a graphite-based cell structure where both contacts are in place before the perovskite crystal formation occurs within the mesoporous scaffold, the photovoltaic performance along with optoelectronic properties are monitored in real time during the crystallization. As perovskite solar cells are prone to spatial heterogeneity, spatially resolved characterization techniques mainly based on photoluminescence spectroscopy, light beam-induced current and thermography are employed to analyze non-uniform optoelectronic properties and quantify local loss mechanisms. A novel characterization method is introduced by the author, allowing for the quantitative assessment of local loss mechanisms. The technique is demonstrated on blade coated perovskite solar cells, which represent a scalable deposition route, and it highlights the detrimental impact of layer non-uniformity on the overall solar cell performance. It presents a powerful tool for the targeted improvement of layer homogeneity and consequential benefit the enhancement of the cell efficiency. In high bandgap perovskite films made from a mixed cation and halide alloy, the local optoelectronic properties are analyzed with micrometer resolution. Non-uniform emission properties are revealed and related to the layer morphology. A subcell-selective analysis of monolithic two-terminal silicon perovskite tandem solar cells is presented, accessing the individual subcells by multi-wavelength photoluminescence spectroscopy. The mapping approach additionally yields spatial distribution of the photoluminescence emission, allowing for the identification of process influences on the two subcells. The results from this thesis generated insights about the perovskite crystal formation and spatial heterogeneities on different length scales. Overall, the findings support the targeted optimization of hybrid organic-inorganic halide perovskite solar cells.
