Special Issue Information

Dear colleagues,

Today, perovskite solar cell (PSC) technology is competing with traditional inorganic photovoltaic, in terms of power conversion efficiency and fabrication costs. At the same time, PSCs have demonstrated surprising potential in combination with the existing technologies in tandem configuration. Passing from lab cells to devices exploitable at the industrial level is a mandatory step. This requires new strategies to overcome issues, such as stability in real working conditions and the scaling-up from lab-scale devices to large-area modules and panels. On one side, the long-term stability is ruled by the architecture of the cell, the materials employed and the interfaces among adjacent layers. On the other side, scaling-up requires proper deposition techniques optimized for large area substrates, usually performed in an environment quite different from the inert atmosphere used for the fabrication of small-area cells.

In this context, the main aim of this Special Issue on “Perovskite Photovoltaics: Strategies to Scale-Up Lab Cells to Modules and Panels” is to provide a wide-ranging state-of-the-art strategy collection for improving perovskite device efficiency and stability. At the same time, it aims to provide a research update on effective approaches to scale up the device production process and the relation with methodologies developed for small area devices aimed to boost efficiency and stability. In this context, this issue will present a detailed overview of perovskite solar cell fabrication from small- to large-area devices, their characterization, and stabilization under real working conditions by identifying, at the same time, future research directions and developments.  The topic of the Special Issue is not limited to single-junction cells and research results on tandem and multi-junction cells based on halide perovskite are welcomed. In addition, the Special Issue includes the consideration of novel approaches in scaling up of encapsulation methods for large-area perovskite solar cells and critical aspects in the methodology of stress and stability tests in ambient—outdoor and laboratory-indoor conditions.

We are pleased to invite you to submit manuscripts for the Special Issue on “Perovskite Photovoltaics: Strategies to Scale-Up Lab Cells to Modules and Panels” in the form of full research papers, communications, and review articles. We look forward to your contribution to this Special Issue.

The industrial exploitation of perovskite solar cell technology is still hampered by the lack of repeatable and high-throughput fabrication processes for large-area modules. The joint efforts of the scientific community allowed to demonstrate high-performing small area solar cells; however, retaining such results over large area modules is not trivial. Indeed, the development of deposition methods over large substrates is required together with additional laser processes for the realization of the monolithically integrated cells and their interconnections. In this work, we develop an efficient perovskite solar module based on 2D material engineered structure by optimizing the laser ablation steps (namely P1, P2, P3) required for shaping the module layout in series connected sub-cells. We investigate the impact of the P2 and P3 laser processes, carried out by employing a UV pulsed laser (pulse width = 10 ns; λ = 355 nm), over the final module performance. In particular, a P2 process for removing 2D material-based cell stack from interconnection area among adjacent cells is optimized. Moreover, the impact of the P3 process used to isolate adjacent sub-cells after gold realization over the module performance once laminated in panel configuration is elucidated. The developed fabrication process ensures high-performance repeatability over a large module number by demonstrating the use of laser processing in industrial production. Full article

Ultrafast pump-probe spectroscopies have proved to be an important tool for the investigation of charge carriers dynamics in perovskite materials providing crucial information on the dynamics of the excited carriers, and fundamental in the development of new devices with tailored photovoltaic properties. Fast transient absorbance spectroscopy on mixed-cation hybrid lead halide perovskite samples was used to investigate how the dimensions and the morphology of the perovskite crystals embedded in the capping (large crystals) and mesoporous (small crystals) layers affect the hot-carrier dynamics in the first hundreds of femtoseconds as a function of the excitation energy. The comparative study between samples with perovskite deposited on substrates with and without the mesoporous layer has shown how the small crystals preserve the temperature of the carriers for a longer period after the excitation than the large crystals. This study showed how the high sensitivity of the time-resolved spectroscopies in discriminating the transient response due to the different morphology of the crystals embedded in the layers of the same sample can be applied in the general characterization of materials to be used in solar cell devices and large area modules, providing further and valuable information for the optimization and enhancement of stability and efficiency in the power conversion of new perovskite-based devices.

Device engineering with proper material integration into perovskite solar cells (PSCs) would extend their durability provided a special care is spent to retain interface integrity during use. In this paper, we propose a method to preserve the perovskite (PSK) surface from solvent-mediated modification and damage that can occur during the deposition of a top contact and furtherly during operation. Our scheme used a hole transporting layer-free top-contact made of Carbon (mostly graphite) to the side of hole extraction. We demonstrated that the PSK/graphite interface benefits from applying a vacuum-curing step after contact deposition that allowed mitigating the loss in efficiency of the solar devices, as well as a full recovery of the electrical performances after device storage in dry nitrogen and dark conditions. The device durability compared to reference devices was tested over 90 days. Conductive atomic force microscopy (CAFM) disclosed an improved surface capability to hole exchange under the graphite contact after vacuum curing treatment. Full article
