A Comprehensive Review of Tandem Solar Cells Integrated on Silicon Substrate: III/V vs Perovskite

Abstract

High-efficiency solar cells with low manufacturing costs have been recently accomplished utilizing different technologies. III-V-based tandem solar cells have exhibited performance enhancement with a recent efficiency of greater than 39% under AM1.5G and 47% under concentration. Integration of such III-V materials on a relatively cheap Silicon (Si) substrate is a potential pathway to fabricate high-efficient low-cost tandem solar cells. Besides, perovskite solar cells, as third-generation thin film photovoltaics (PV), have been meteorically developed at a reasonable cost. At present, there are still questions for cost reduction of perovskite materials and solar cell modules because of their limited commercialization. In this review, stacking Si solar cells with III-V material to form Si-based III-V tandem solar cells is presented with different integration technological routes. Also, perovskite/Si tandem solar cells have been reviewed alongside their main engineering challenges introduced through the fabrication of perovskite-based tandem solar cells. Finally, a comparison between III-V tandem solar cells, Si-based III-V tandem solar cells, and perovskite-based tandem solar cells is introduced so that the best technology for a specific application could be determined. The review provides a comprehensive study of two different technologies (III/V and Perovskite) to demonstrate the most valuable cost reduction availability for each.

Study the optimization of offshore floating PV power systems and its application

“…When D is 3 m, the linear loss of the amount of direct solar radiation in the floating PV system is minimal, and the optimal state is reached. Since only geometric factors, including D, H, and ȕ are considered, the loss of the offshore PV system is always less than that of the onshore PV system at the same value of D. For bi-PV modules, the power generation is dominated by the front surface and could be further enhanced by the rear surface to a certain degree [4]. The power generation from the rear surface is more significantly determined by the temperature (directly related to the H value) and reflectivity (Refl).…”

On Numerical Modelling and an Experimental Approach to Heterojunction Tandem Solar Cells Based on Si and Cu2O/ZnO—Results and Perspectives

“…TiO 2 behaved as an active material that absorbed photons and converted them into electric current, having a band gap around 3.2-3.8 eV, which allows the effective absorption of UV light [33,34]. The influence of TiO 2 inclusion on the following SC characteristics, respectively, was considered: (1) the open-circuit voltage (V oc ); (2) the short-circuit current (J sc ); (3) the SC conversion efficiency (η); and (4) the fill factor (FF). In order to obtain essential knowledge of SHTSC design, it is required to determine the optimized values of the SC physical parameters.…”

Aesthetic and functional aspects of BIPV – an architectural outlook

“…Further development has either already occurred or is anticipated due to thin--film cell technology and third-generation PV cells, mainly DSSC (Parasuraman, 2023), organic (Prasad et al, 2013), perovskite (Park, 2015), as well as tandem solutions that combine more than one semiconductor material (Saif et al, 2023), such as graphene-based PV cells, which are known as fourth-generation cells (Pastuszak & Węgierek, 2022). nineteen-eighties application in architecture (based on adding a PV installation to an existing facility)…”
