Hybrid halide perovskites are among the most promising candidates for next-generation photovoltaics. The most investigated perovskite solar cells are lead based, which poses environmental concerns, making finding sustainable alternatives a pressing issue. ...

The discovery of self-assembled molecular layers (SAMLs) containing anchoring groups such as COOH and PO3H as efficient hole-selective materials (HSMs) in p-i-n perovskite solar cells (PSCs) is pivotal to enhancing the interaction between HSMs and perovski ...

Organic semiconductors (OSCs) have emerged as promising active layers for photoanodes to drive photoelectrochemical (PEC) oxidation reactions. Interfacing an OSC with an inorganic electron transport layer (ETL) is key to enabling both high performance and ...

Artificial photosynthesis is considered to be a promising approach for energy storage and global warming mitigation. However, the suboptimal selectivity of products and the low conversion efficiency of CO2 persist as challenges, driving continuous interest ...

The lateral structure of gallium nitride (GaN) semiconductors enables monolithic integration of logic and power devices, which offers promise to miniaturize bulky converters into a compact package. However, the concentrated heat that arises from this dense ...

Applications demanding imaging at low-light conditions at near-infrared (NIR) and short-wave infrared (SWIR) wavelengths, such as quantum information science, biophotonics, space imaging, and light detection and ranging (LiDAR), have accelerated the develo ...

Certain biological materials, such as chameleons and peacocks, display bright and vivid colors. These colors are created by the constructive interference of light that is reflected from colloidal crystals, generating the so-called structural colors. These ...

Hexakis(hexyloxy)triphenylene (HAT6) discotic liquid crystal is employed as a transparent hole-transporting material (HTM) for perovskite solar cells (PSCs) and a power conversion efficiency (PCE) of 15.7% is obtained, which is the highest using HAT6 type ...

Inverted perovskite solar cells (PSCs) promise enhanced operating stability compared to their normal-structure counterparts1–3. To improve efficiency further, it is crucial to combine effective light management with low interfacial losses4,5. Here we devel ...

The structural properties of octahedral sites (B-Oh) in spinel oxides (AB(2)O(4)) play vital roles in the electrochemical performance of oxygen-related reactions. However, the precise manipulation of AB(2)O(4) remains challenging due to the complexity of t ...

We evaluate the effect of storage conditions of uncured encapsulant rolls and the potential consequences on photovoltaic (PV) module performance. We show the impact of residual water trapped inside laminated double glass PV modules after lamination and dur ...

Predicting the performance of solar cells though analytical models is important for the theory-guided optimization of these devices. Earlier models neglect the impact of the optical generation in the quasi-neutral regions of a perovskite solar cell. Here, ...
