of the PSCs from small area lab-scale cells to large area modules has been realized in various reports through different scalable techniques [1–3]. In one hand, wasting of the hazardous materials during deposition of the perovskite films make a critical challenge on the socio-economic interest and environmental impacts of the perovskite solar cells (PSCs) [4]. Optimization of the recently applied scalable deposition techniques for solution-based fabrication of efficient and stable perovskite solar modules (PSMs) is usually a challenging activity with low reproducibility from batch-to-batch production [5,6]. On the other hand, recent advances in 2-dimentioanl materials and surface passivation strategies opened a promising gate to pass the stability bottlenecks [7]. However, there are still some challenging points in terms of the materials’ type and deposition processes which induced some limitations against commercial application of such strategies [8]. In addition, most of the stability assessment reports have been realized based on lab-scale cells and despite a few reports [9–13], there is a lack in the literature for standard stability assessments of the perovskite solar modules.
Here, two innovative strategies have been introduced for scalable and zero-waste fabrication and highly improvement of the long-term stability of the PSMs against various thermal and light stresses. Firstly, a bulky molecular linker toward formation of novel co-crystalline 2D perovskite layers, resulting a multifunctional passivating of various types of the perovskite defects. By using double cation underlaying 3D perovskite (DCP) and top layer 2D perovskite PSMs with 9.0 cm2 and 48 cm2 active area have been fabricated, reaching to 20.2 % and 17.5 % PCE on the module active area, respectively. Fabricated modules showed promising stability against thermal and light soaking stresses (corresponding to the ISOS protocol) with >1100 h T93 thermal stability at 85 ˚C and >1100 h T86 under Maximum Power Point (MPP) operation condition under 1-sun illumination. Lastly, a zero-waste blade-spin/blade coating process is successfully applied for deposition of the 3D/2D perovskite phases shows the potential for >90% decrease of the Operational Expenditure (OPEX) by breakdown the materials costs from 1.99 €/m2 in spin-coating method to 0.18 €/m2 in blade-spin/blade coating approach.
