Monolithic two-terminal (2T) perovskite/CuInSe2 (CIS) tandem solar cells (TSCs) combine the promise of an efficient photovoltaic (PV) technology with simplicity all-thin-film device architecture that is compatible flexible and lightweight PV. In this work, we present first-ever 2T perovskite/CIS TSC a power conversion efficiency (PCE) approaching 25% (23.5% certified, area 0.5 cm2). The relatively planar surface profile narrow band gap (∼1.03 eV) our CIS bottom cell allow us to exploit...
Key advances on triple-junction perovskite–perovskite–Si solar cells with an unprecedented efficiency of 24.4% and enhanced long-term thermal stability are reported via the development high-performance middle perovskite cell.
Over the past decade, impressive progress in power conversion efficiency (PCE) of organometallic halide perovskite solar cells (PSCs), coupled with their ready integration into tandem cells, has led them to approach PCEs 30% for a silicon bottom subcell. However, complementary technology perovskite/copper indium gallium selenide (CIGS) been thus far unable reach similar values. Herein, further advance 4T perovskite/CIGS tandems is demonstrated, increasing PCE up 27.3% via systematic...

Detailed simulations are needed to assess performances this morphology configuration (thick configuration). In work, in-depth optical and energy yield (EY) performed compare thick other relevant configurations photovoltaics....
Abstract Many economic and environmental studies on novel perovskite solar cells (PSCs), published ex post the development stage to investigate market competitiveness, have focused laboratory‐scale PSC architectures that are not amenable for upscaling. In this paper, we evaluate potential sustainability of a scalable carbon‐electrode‐based by benchmarking it dominating c‐Si photovoltaics CIGS thin film photovoltaics. The analysis covers PSCs full lifecycle, at module system levels...
Abstract All‐perovskite two‐terminal tandem photovoltaics offer high power conversion efficiencies (PCEs) that can surpass the limits of single‐junction photovoltaics. In this study, energy yield (EY) simulations are performed to assess performance bifacial all‐perovskite solar cells. Under standard test conditions, in absence albedo, tandems demonstrate a 4.9% relative lower PCE compared equivalent monofacial due transparency losses at semitransparent rear side. However, under realistic...
Abstract A phosphor‐particle‐loaded microlens array on a polymer substrate offers an attractive unclonable anticounterfeiting label design. random pattern of bright emission points is created due to the coincidences light focused by with underlying phosphor microparticle. The change point patter angle incident (owing shift in locations focal points) makes labels unclonable. This work examines authentication such using single smartphone. smartphone flashlight provides illumination whereas...
All-perovskite two-terminal tandem solar cells, comprising two or more junctions, offer high power conversion efficiencies (PCEs) that exceed the limits of single-junction photovoltaics. Realizing high-efficiency SCs requires carefully optimizing photoactive layer, front electrodes, and functional layers. Here, we first aim to determine optimal device architecture, i.e., perovskites bandgaps optimum layer thicknesses, for standard test conditions (STCs). We then optimize energy yield (EY)...
Tunneling junctions are pairs of electrodes separated by gaps a few nanometers that allow electrons to tunnel across the gap. great importance for applications such as label-free biomolecule sensing and single molecule electronics, but their fabrication remains difficult laborious. In this paper, we present simple 2-stage process tunneling consisting electrode made gold (Au). This is achieved combining novel methodology fabricating crack-defined Au nanowires at wafer-scale with constant...
