Abstract Two-terminal (2-T) perovskite (PVK)/CuIn(Ga)Se 2 (CIGS) tandem solar cells (TSCs) have been considered as an ideal cell because of their best bandgap matching regarding to Shockley–Queisser (S–Q) limits. However, the nature irregular rough morphology commercial CIGS prevents people from improving device performances. In this paper, D-homoserine lactone hydrochloride is proven improve coverage PVK materials on surfaces and also passivate bulk defects by modulating growth crystals. addition, minority carriers near PVK/C60 interface incompletely passivated trap states caused recombination. A surface reconstruction with 2-thiopheneethylammonium iodide N , -dimethylformamide assisted passivates defect sites located at grain boundaries. Meanwhile, LiF used create field effect, repelling hole away C60 thus reducing As a result, 2-T PVK/CIGS yielded power conversion efficiency 24.6% (0.16 cm ), one highest results for TSCs our knowledge. This validation underscores potential methodology in achieving superior performance cells.

Enhanced Bifacial III–V/Silicon Multijunction Solar-Cell-Based Promising Structure of c-Si Bottom Cells

ACS Applied Energy Materials, Год журнала: 2025, Номер unknown

Опубликована: Янв. 12, 2025

We present a structural design for four-terminal III–V/crystalline silicon (c-Si) multijunction (MJ) device based on optimized bifacial illumination. The proposed configuration consists of triple-junction top cell incorporating gallium indium phosphide (GaInP), arsenide (InGaAs), and germanium (Ge), paired with tunnel oxide passivating contact (TOPCon) as the bottom cell. TOPCon effectively enhances transmission albedo-reflected light into c-Si absorber, delivering superior performance compared to conventional heterojunction cells. With an additional rear illumination 0.3 sun, efficiency increases by 9.61%. Bifacial overall MJ 20.77% monofacial device. power conversion (PCE) GaInP/InGaAs/Ge/TOPCon devices reaching 35.70%, this demonstrates significant potential advancing high-efficiency solar technologies.

The p-i-n type perovskite solar cells with a nickel oxide (NiOx) hole transport layer in combination self-assembled monolayers (SAMs) have high power conversion efficiency (PCE) of over 26%. surface properties the SAM significant impact on growth and crystallization film. In meanwhile, defects formed during thermal annealing at interface would act as charge recombination centers, decreasing device performance stability. To address these issues, this work introduces 3,4,5-trifluorophenylboronic acid (3,4,5-3FPBA) interfacial modification to improve buried that enable better With 3,4,5-3FPBA layer, based composition Cs0.05(FA0.98MA0.02)0.95Pb(I0.95Br0.05)3, increased from 21.99% 24.02%. A similar improvement was observed for Cs0.05FA0.82MA0.13Pb(I0.85Br0.15)3, where 21.87% 22.76%. universality has been confirmed. addition, resulting showed improved stability, maintaining 75% its initial after 500 h continuous heating 85 °C unencapsulated devices.

Photoinduced phase segregation in wide-bandgap mixed-halide perovskite solar cells

Energy Materials and Devices, Год журнала: 2024, Номер 2(2), С. 9370037 - 9370037

Опубликована: Май 30, 2024

Wide-bandgap (WB) mixed-halide perovskite solar cells (PSCs) play a crucial role in perovskite-based tandem (TSCs), enabling them to exceed the Shockley-Queisser limits of single-junction cells. Nonetheless, lack stability WB films due photoinduced phase segregation undermines PSCs and their TSCs, thus impeding commercialization TSCs. Many efforts have been made suppress significant progresses obtained. In this review, we elaborate mechanisms behind its impact on photovoltaic performance devices. The importance advanced characterization techniques confirming are comprehensively summarized. Beyond that, effective strategies alleviate mixed halide systematically assessed. Finally, prospects for developing highly efficient stable application also presented.
