Semitransparent perovskite solar cells (ST-PSCs) are very attractive due to their potential applications in single junctions for building-integrated photovoltaics (BIPV) and in tandem PV technology using low-bandgap bottom solar cells. Despite the high efficiency achieved, the ST-PSCs still suffer low bifaciality, which can limit their overall...

Perovskite-based multijunction solar cells are a potentially cost-effective technology that can help surpass the efficiency limits of single-junction devices. However, both mixed-halide wide-bandgap perovskites and lead-tin narrow-bandgap perovskites suffer from non-radiative recombination due to the formation of bulk traps and interfacial...

Recently perovskite/crystalline Si (cSi) tandem cells draw considerable attention because their high efficiency can reduce the levelized cost of electricity and increase the power density of photovoltaics (PVs) to accelerate the energy transition. While the theoretical limits for tandem cells are well known, the practical limits are less clear....

—4-terminal tandem technology is a straightforward approach to bring to the market perovskite/crystalline silicon tandem modules. However, dealing with 4 terminals poses a challenge at system level for practical deployment. We have produced large area 4-terminal perovskite/crystalline silicon tandem modules for a study of the performance of a 2...

Sputtered transparent conducting oxides (TCOs) are widely accepted transparent electrodes for several types of high-efficiency solar cells. However, the different sputtering yield of atoms makes stoichiometric transfer of target material challenging for multi-compounds. Additionally, the high kinetic energies of the arriving species may damage...

To achieve the highest performance using perovskite solar cells it is necessary to understand all the dominant mechanisms which affect the operation of solar cell. Here, we have investigated the bulk and interface trap-assisted recombination processes in the solar cells with p-i-n architecture. These studies are based on the numerical and...

Perovskite semiconductors hold a unique promise in developing multijunction solar cells with high-efficiency and low-cost. Besides design constraints to reduce optical and electrical losses, integrating several very different perovskite absorber layers in a multijunction cell imposes a great processing challenge. Here, we report a versatile two...

In order to achieve the highest performance of organometal trihalide perovskite solar cells, it is required to recognize the dominant mechanisms which play a key role in a perovskite material. In the following studies, we have focused on the interfacial recombination between the hole transporting layer (HTL) and the perovskite CH3NH3PbI3 in...

In this work, efficient rigid and flexible semi-transparent perovskite solar cells (ST-PSCs) were prepared in inverted (light incidence through hole transport layer) configuration. All layers were deposited by a combination of low-temperature solution-based, sputtering and spatial atomic layer deposition (sALD) techniques, which can be...

In order to commercialize the perovskite solar cells (PSC) technology, efficient and industrial deposition methods over large areas have to be adopted, and the device architectures have to provide long term stability. In this work we combine several upscalable deposition methods to develop a stable semitransparent PSC. The control of the...

In this contribution the development of highefficiency planar semi-transparent perovskite solar cells (STPSCs) for tandem applications is presented. The ST-PSC absorber layer, and electron and hole transport layers were processed using spin coating. The near-infrared (NIR) transmission of the ST-PSC is optimized by improving ITO material quality...

Two factors have coincided to stimulate the recent spur in interest for hybrid tandem PV technology based on crystalline silicon – the fact that balance-of-system (BOS) costs are increasingly dominating turnkey system costs, which strengthens the effect of high efficiency in reducing Wp costs, and the discovery of perovskite solar cells as a...

The purpose of the work is to investigate high-efficient and stable 4-terminal perovskite/c-Si tandem devices. Hybrid tandems of c-Si bottom cells and perovskite top cells are perhaps the most promising candidates to reduce the levelized cost of electricity by increasing the overall tandem cell efficiency. To turn this promise in a commercial...

In this study, the fabrication of highly efficient and durable flexible inverted perovskite solar cells (PSCs) is reported. Presynthesized, solution-derived NiOx and ZnO nanoparticles films are employed at room temperature as a hole transport layer (HTL) and electron transport layer (ETL), respectively. The triple cation perovskite films are...

The industrialization of perovskite solar cells (PSC) require processes to efficiently deposit the constituent layers over large areas. In this work we optimized the use of slot die coating process for both sheet-to-sheet (S2S) and roll-to-roll (R2R) manufacturing. Particular focus have been put on the control of the uniformity of perovskite...

In order to bring the organo-lead halide perovskite solar cells (PSC) towards the commercialization, the device stability needs to be drastically improved. Our approach relies on the introduction of a compact metal oxide (MeO) layer in a p-i-n planar architecture by means of atmospheric pressure spatial atomic layer deposition (s-ALD) technique....

This paper models and compares the energy yield to be expected from bifacial 2-terminal (2T) and 4-terminal (4T) hybrid perovskite/crystalline silicon tandem modules. Following the work by Asadpour et al. the comparison includes 2T tandem cells employing a thick perovskite absorber layer with standard band gap, which in monofacial operation have...
