Factors and governing mechanisms influencing the open circuit voltage – a key determinant for improving device performance efficiency.
Metal halide perovskite solar cells (PSCs) continue to improve their power conversion efficiency over 25.5%, which is at the same level as silicon cells.
An ultra-thin indium tin oxide interlayer design was developed for interfacing perovskite solar cells with Si thereby minimising shunting effects large area monolithic tandem devices.
Lead halide perovskite solar cells (PSCs) have achieved remarkable efficiencies comparable to those of their established silicon counterparts at a very fast pace. Moreover, solution-processable facile technologies offer low-cost, low-temperature, scalable fabrication these cells. Numerous studies focused on improving the performance, stability, and processing PSCs. However, potential lead toxicity poor long-term stability impede commercialization. In recent years, several developed novel...
The critical width Lc for misfit dislocation generation has been determined molecular beam epitaxy grown strained InxGa1−xAs (0.1<x≤1) quantum wells in a GaAs matrix by means of photoluminescence measurements. For the full alloy region dependence Lc(x) is good agreement with theoretical expression proposed J. W. Matthews and A. E. Blakeslee [J. Cryst. Growth 27, 118 (1974)].
Organic–inorganic hybrid perovskite solar cells (PSCs) have emerged as a new class of optoelectronic semiconductors that revolutionized the photovoltaic research in recent years. The present numerous advantages include unique electronic structure, bandgap tunability, superior charge transport properties, facile processing, and low cost. Perovskite demonstrated unprecedented progress efficiency its architecture evolved over period last 5–6 years, achieving high power conversion about 22%...
Tin oxide (SnO2) has been reported as a promising electron transport layer (ETL) for planar heterojunction perovskite solar cells (PSCs). This work reports low temperature solution-processed bilayer SnO2 an efficient ETL in gas-quenched planar-heterojunction methylammonium lead iodide (MAPbI3) cells. nanoparticles were employed to fill the pin-holes of sol–gel and form smooth compact structure. The PCE devices increased by 30% compared with reference device Jsc, Voc, FF improved...
Inorganic cesium lead triiodide (CsPbI3) perovskite materials are becoming increasingly attractive for use in perovskite/silicon tandem solar cells, due to their almost ideal band gap energy (Eg) of about 1.7 eV. To be useful as photovoltaic absorbers, the CsPbI3 must form cubic or black phase (α-CsPbI3). do so at relatively low temperatures, hydroiodic acid (HI) is required a solution additive. This paper demonstrates cells with an efficiency 6.44%, formed using HI concentration 36 μL/mL....
The present review rationalizes the significance of metal oxide semiconductor (MOS) interfaces in field photovoltaics and photocatalysis. This perspective considers role interface science energy harvesting using organic (OPVs) dye-sensitized solar cells (DSSCs). These include large surface area junctions between photoelectrodes dyes, interlayer grain boundaries within photoanodes, photoactive layers top bottom contacts. Controlling collection minimizing trapping charge carriers at these is...
Organic solar cells possess multiple desirable traits, such as low cost, flexibility, and semitransparency, which opens up potential avenues unavailable to other technologies, a prime example of this being window applications. For specific application, delicate balance between the transmission light through device power conversion efficiency (PCE), dependent on amount absorbed, must be optimized. Here, we report high-efficiency semitransparent based novel fullerene-free material system....
Opaque and semitransparent organic solar cells (ST‐OSCs) have made tremendous progress in recent years. Efficiencies over 18% 13% been demonstrated for opaque ST‐OSCs, respectively. OSCs do not contain unfavorable elements such as lead, which makes them available broader potential applications when compared with other lead‐contained thin‐film cells. There has also the extremely appealing promising emerging building‐integrated photovoltaics. Herein, a review field is presented helping...
Abstract Lead (Pb) halide perovskite solar cells (PSCs) exhibit impressive power conversion efficiencies close to those of their silicon counterparts. However, they suffer from moisture instability and Pb safety concerns. Previous studies have endeavoured address these issues independently, yielding minimal advancements. Here, a general nanoencapsulation platform using natural polyphenols is reported for Pb‐halide PSCs that simultaneously addresses both challenges. The polyphenol‐based...
