Abstract Window glazing plays an essential role to modulate indoor light and heat transmission, which is a prospect save the energy cost in buildings. The latest photovoltachromic technology has been regarded as one of most ideal solutions, however, achieve full-frame size (100% active area) high-contrast ratio (>30% variable visible wavelength) for smart window applicability still challenge. Here we report device combining full-transparent perovskite photovoltaic ion-gel based...
Abstract Perovskite/silicon tandem solar cells (TSCs) are promising candidates for commercialization due to their outstanding power conversion efficiencies (PCEs). However, controlling the crystallization process and alleviating phases/composition inhomogeneity represent a considerable challenge perovskite layers grown on rough silicon substrates, ultimately limiting efficiency stability of TSC. Here, this study reports “halide locking” strategy that simultaneously modulates nucleation...
Rapid processing technologies of perovskite solar cells (PSCs) offer an exciting approach to raise the rate production. Herein, a rapid microwave-annealing process (MAP) is reported replace traditional hotplate annealing (HAP) and period reduced less than 1 min. Benefiting from penetrability simultaneity microwave irradiation, MAP method can effectively eliminate miscellaneous phases thus achieve >1 µm large-size crystal grains in films. These treated films exhibit pure crystalline phase,...
Advanced photonic integrated circuits require large-scale integration of high-speed electro-optic (EO) functional components on a chip. Low power consumption and high operation speed are thus key metrics for almost all EO devices. Here, we demonstrated ring resonator modulator based lead zirconate titanate (PZT) SiO2/Si substrate. The ridge waveguides were employed to keep large spatial overlap between the optical field electric within PZT layer. device exhibits data rate 56 Gbit/s...

Developing lead zirconate titanate (PZT)-based electro-optic (EO) modulators is vital for integrated photonics. The high annealing temperature required the processing of PZT thin films restricts their compatibility with modern complementary metal-oxide-semiconductor (CMOS) technology.

Based low-temperature films, we subsequently designed...
Abstract Benefiting from the rapid development on chloride incorporated perovskite materials, nowadays, novel device fabricating techniques have sparked a new vision of ultraviolet photodetectors (UVPDs), which is moving toward higher precision, lower energy consumption, and greater miniaturization. Nevertheless, natural poor solubility precursors for perovskites has limited their processability achieving high‐performance self‐driven photovoltaic‐type UVPDs. Herein, ball‐milling pretreated...
For achieving high-performance p-i-n perovskite solar cells (PSCs), hole transporting materials (HTMs) are critical to device functionality and represent a major bottleneck further enhancing stability efficiency in the inverted devices.

Three conjugated polymers based on different linkage sites of carbazole repeat units, 3,6-PCzTPA, 2,7-PCzTPA, and 3,6-2,7-PCzTPA, were obtained through judicious molecular engineering. We observed that structure differences between 2,7- 3,6-carbazole could significantly influence intra- intermolecular architectures electronic states materials. Herein, 3,6-PCzTPA 3,6-2,7-PCzTPA with units exhibited higher hole mobilities owing to the formation radical cations, compared 2,7-PCzTPA...
Halide perovskites with low-dimensionalities (2D or quasi-2D) have demonstrated outstanding stabilities compared to their 3D counterparts. Nevertheless, poor charge-transporting abilities of organic components in 2D lead relatively low power conversion efficiency (PCE) and thus limit applications photovoltaics.
