Bifacial semi-transparent perovskite (PVSK) solar cell is a promising candidate to achieve high photo-electrical conversion efficiency (PCE) in a tandem structure with Si solar cells. The gap between lab-scale cells and large area modules needs to be closed using innovative patterning technology. In this paper we demonstrate that a single nanosecond pulsed laser (wavelength 532 nm, pulse duration 7 ns) can be used to perform all scribing processes, i.e. P1, P2 and P3, to manufacture PVSK solar modules. Compared to picosecond or femtosecond lasers reported in the literature, our approach has the advantages of high stability and low cost, and is thus applicable to large scale manufacturing of PVSK solar modules. Detailed laser processing parameters such as laser power and overlap ratio etc. have been studied to achieve optimal results for each scribing process. A mini module with two cells was fabricated on a 2 × 2 cm2 substrate, showing an active area efficiency of 12.5%, FF of 72.4%, and high GFF of 94%.

The selective laser melted (SLM) Ti–6Al–4V cellular solid is a promising material in biomedical and other applications. The mechanical properties of the SLM Ti–6Al–4V cellular material are predominantly controlled by the design of the cellular structure. The objective of this study was to investigate the uniaxial compressive properties and compressive fatigueperformance of the SLM Ti–6Al–4V cellular solid with a new cuboctahedron unit cell reinforced by four diagonal strutsand two horizontal struts along the X and Y axes. The infuences of hot isostatic pressing (HIP) on the various mechanicalproperties were also examined. The results showed a smoother stress–strain curve and fewer stress oscillations in the HIPspecimen than in the SLM specimen. The HIP process slightly decreased the yield strength of the SLM sample from 55 to52 MPa. Under uniaxial compressive stress, the SLM and HIP specimens exhibited layer-by-layer fracture and diagonalshear fracture, respectively. Furthermore, the HIP treatment signifcantly increased the fatigue performance and improved thefatigue endurance ratio at 106cycles from 0.15 to 0.35. The HIP treatment contributed to several positive efects, includingphase transformation from brittle α′ to α + β, the elimination of strut porosity and residual stress, an increase in lath size,and a better combination of strength and ductility, thereby improving the fatigue performance. The efects of stress mode onthe fracture mechanism were also clarifed using in situ observation in combination with digital image correlation.
