To achieve large-area monolithic-integrated modules, a scribing process, dividing into multiple cells for series connection, is indispensable. Despite numerous merits laser scribing can offer, further improvement is required for high-quality solar module. Picosecond laser, generally accepted as an efficient tool to suppress thermal impact, often causes problems in achieving a shunt-free P1 scribing process that isolates the back contact, typically bi- or multilayered Mo thin films, due to edge deformation as a source of shunt. In this study, we experimentally compare the performance of picosecond and nanosecond lasers in scribing bilayered Mo films of different microstructures on flexible polyimide through morphological analysis and shunt evaluation for selected scribing conditions. Thermal analysis and time-resolved measurement of laser-induced emission further elucidate relevant scribing mechanisms. It will be shown that nanosecond lasers, usually not a preferred solution for temperature-sensitive architectures, have significant merits in scribing complex multilayered structures of relatively large thickness, preferentially launching indirect interfacial heating mechanism for optically nontransparent film–substrate combinations.</p>","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"9 9","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143909391","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The goals of this investigation are the optimization of the polysilicon tunnel junction and the comparison of different processing pathways to enable a lean process integration. Various process routes with different annealing sequences for the polysilicon tunnel junction were examined, using a laser-based rapid thermal process (RTP) and a conventional furnace anneal. The main challenge is to control the interdiffusion of p- as well as n-type dopants at the tunnel junction interface during the thermal activation process. On pre-annealed n-tunnel oxide passivating contact (TOPCon) layers, a low process temperature for the p-polysilicon activation is beneficial without the necessity of an additional diffusion blocking layer. If the n-TOPCon and the p-polysilicon layer are annealed simultaneously in one RTP, high temperatures are required, which are enabled by a diffusion blocking SiN<sub><i>x</i></sub> interlayer at the tunnel junction interface.

However, challenges such as high-defect densities at grain boundaries, nonradiative recombination, and instability severely limit their performance. In this study, we introduce a molecule of 2-methylthio-2-imidazoline hydriodide (MDHI) as a passivator to address the grain boundary defects by forming MDHI–PbI<sub>2</sub> complex. X-ray diffraction and scanning electron microscopy results demonstrate that MDHI effectively suppressed the formation of PbI<sub>2</sub>, thereby greatly enhanced the crystallinity of PVKs with doubled grain size, which validly reduced defect densities and minimized recombination losses. As a result, an enhanced power conversion efficiency (PCE) of 20.19% (0.09 cm<sup>2</sup>) is observed for a bandgap of 1.68 eV PVK solar cells (PSCs) with MDHI modification, which can retain over 90% of its initial efficiency after 1000 h of continuous illumination, demonstrating significantly promoted operational stability, while the control one only shows 17.96% PCE and remains 60% of its pristine efficiency. Eventually, the MDHI-modified WBG PVK–silicon tandem devices achieve a champion PCE of 30.46% (1.07 cm<sup>2</sup>).

One of these challenges is the accurate optoelectronic assessment of perovskite films with photoluminescence (PL) spectroscopy. In this work, we study effects of optical self-absorption on the PL of perovskite films conformally coated on industry-compatible textured silicon with pyramid heights ranging from &lt;1 to &gt;6 µm. Our findings indicate that with increasing pyramid height, the PL peak energy shows a blueshift of 20–30 meV. Similarly, increasing the perovskite thickness on a fixed texture pattern induces a redshift. Three-dimensional confocal laser scanning PL microscopy, combined with statistical ray optical simulations, reveals that photon reabsorption in the perovskite film plays an important role in the texture-dependent and thickness-dependent PL responses.
