Perovskite-based solar cells have shaken the photovoltaic sector achieving more than 25% efficient laboratory-scale solar cells in around 10 years. Now, they are on the way to breaking the 30% efficiency threshold by being coupled with established technologies such as Silicon and CI(G)S forming a multijunction configuration.
As demand for a more sustainable and decentralized electricity system increases, low-cost and lightweight thin-film based multijunction are an ideal match for integrated PV requirements. On the other hand, urban environments increase stress-induced losses due to partial shading and weather alterations on PV strings. Most importantly, both thin-film technologies (CIGS and Perovskite) have shown lower reverse breakdown voltages[1-2], which increases the need for bypass diodes and in some cases reverse bias-induced degradation [3]. It is therefore essential to consider alternative module designs to optimize the desired power outputs and increase the long term reliability of BIPV/VIPV systems.
In this study, we designed an improved SPICE simulation[4] of a PV module to assess the impact of material’s and design’s parameters under partial shadow conditions, with a focus on alternative designs for thin-film based integrated photovoltaics applications. To guarantee safe real life installation and operation, realistic limitations are also taken into consideration as boundary conditions. As a result of our research, we present suitable alternative designs based on different absorber materials, sizes, and interconnection schemes and inclusive of 2 terminal, current matched multijunction CIGS/Perovskite devices. For each configuration, we also report the local impact of shadow-induced thermal losses based on a SPICE equivalent thermal circuit.

nanoGe is a prestigious brand of successful science conferences that are developed along the year in different areas of the world since 2009. Our worldwide conferences cover cutting-edge materials topics like perovskite solar cells, photovoltaics, optoelectronics, solar fuel conversion, surface science, catalysis and two-dimensional materials, among many others.
Previously nanoGe Spring Meeting (NSM) and nanoGe Fall Meeting (NFM), MATSUS is a multiple symposia conference focused on a broad set of topics of advanced materials preparation, their fundamental properties, and their applications, in fields such as renewable energy, photovoltaics, lighting, semiconductor quantum dots, 2-D materials synthesis, charge carriers dynamics, microscopy and spectroscopy semiconductors fundamentals, etc.
International Conference on Hybrid and Organic Photovoltaics
International Conference on Hybrid and Organic Photovoltaics (HOPV) is celebrated yearly in May. The main topics are the development, function and modeling of materials and devices for hybrid and organic solar cells. The field is now dominated by perovskite solar cells but also other hybrid technologies, as organic solar cells, quantum dot solar cells, and dye-sensitized solar cells and their integration into devices for photoelectrochemical solar fuel production.
Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics
The main topics of the Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP) are discussed every year in Asia-Pacific for gathering the recent advances in the fields of material preparation, modeling and fabrication of perovskite and hybrid and organic materials. Photovoltaic devices are analyzed from fundamental physics and materials properties to a broad set of applications. The conference also covers the developments of perovskite optoelectronics, including light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
The International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics (NIPHO) is the best place to hear the latest developments in perovskite solar cells as well as on recent advances in the fields of perovskite light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
