“…I–V characteristics curve can be also employed to detect solar cell defects [98] . This can be done by measuring the Current (I)‐Voltage (V) curve under different radiation and temperature levels [99,100] . The graph will describe the solar cell conversion capacity in terms of electrical efficiency as well as fill factor. Visual examination is an indicative test for detecting any major flaws in a PV module [101] .…”

In recent years, floating photovoltaic (FPV) technologies have gained more importance as a key source of clean energy, particularly in the context of providing sustainable energy to buildings. The rise of land scarcity and the need to reduce carbon emissions have made FPV systems a cost‐effective solution for generating electricity. This review article aims to explore the rapidly growing trend of floating PV systems, which can be a practical solution for regions with limited land areas. The article discusses the structure of the PV modules used in FPV plants and key factors that affect site suitability choice. Moreover, the article presents various techniques for cooling and cleaning FPV to keep optimal performance and discusses feasible trends and prospects for the technology. Finally, this paper proposes the potential integration of FPV systems with other technologies to enhance energy generation efficiency and discusses other research aimed at the advancement of the technology. By examining the various features of FPV systems, this review article contributes to understanding the advantages and challenges associated with using this sustainable energy technology in different regional contexts.

“…The test results showed that the residual stress in amorphous silicon was approximately 466 MPa (compressive stress); when the tensile strain reached 0.9%, the photovoltaic properties of the solar cells began to degrade [102]. Kim and Cheong [103] obtained the current-voltage curves of monocrystalline silicon solar cells with a fiber composite as the backsheets through tensile tests. The test results showed that as the tensile strain increased, cracks appeared on the surface and in the interior of the solar cells and then expanded, eventually resulting in a reduction in the power generation efficiency [103].…”

The energy crisis and environmental pollution have promoted the rapid development of renewable solar technology. Building integrated photovoltaics (BIPV) is an important field for the future development of solar energy. This review presents the mechanical property studies of existing BIPV and analyzes its research status to offer advice for engineering applications. By analyzing the types and mechanical characteristics of solar cells in the existing BIPV and determining the load conditions that need to be considered in different application modes, this paper summarizes the relevant existing studies at the photovoltaic material, cell and component levels and offers corresponding suggestions for mechanical research, which consequently results in the proposal of a new BIPV structure. Since the mechanical properties of BIPV have seldom been studied, and research on practical engineering applications is lacking, further comprehensive and in-depth research is needed to promote the safe and reliable application and popularization of photovoltaic building integration.

“…Modulesubstrate-induced thermal misfit stresses can also occur, but usually show a lower impact on the strain in the cells than in the encapsulating material. 41,42 The Al-Si mismatch stress however can cause interface debonding or crack propagation through the Si layer, especially when the surface is textured. An upper temperature limit can be derived following a procedure by Xu et al 43 Here, the bilayer is assumed to be flattened under pressure and bonded to a rigid substrate.…”

Kerfless exfoliated thin crystalline Si wafers with Al metallization layers for solar cells

We report on a kerfless exfoliation approach to further reduce the costs of crystalline silicon photovoltaics making use of evaporated Al as a double functional layer. The Al serves as the stress inducing element to drive the exfoliation process and can be maintained as a rear contacting layer in the solar cell after exfoliation. The 50-70 lm thick exfoliated Si layers show effective minority carrier lifetimes around 180 ls with diffusion lengths of 10 times the layer thickness. We analyze the thermo-mechanical properties of the Al layer by x-ray diffraction analysis and investigate its influence on the exfoliation process. We evaluate the approach for the implementation into solar cell production by determining processing limits and estimating cost advantages of a possible solar cell design route. The Al-Si bilayers are mechanically stable under processing conditions and exhibit a moderate cost savings potential of 3-36% compared to other c-Si cell concepts.
