Slot-Waveguide Silicon Nitride Organic Hybrid Distributed Feedback Laser

Scientific Reports (2019)

Florian Vogelbacher Martin Sagmeister Jochen Kraft Xue Zhou Jinhua Huang

One of the major barriers for a widespread commercial uptake of silicon nitride photonic integrated circuits for cost-sensitive applications is the lack of low-cost monolithically integrated laser light sources directly emitting into single-mode waveguides. In this work, we demonstrate an optically pumped organic solid-state slot-waveguide distributed feedback laser designed for a silicon nitride organic hybrid photonic platform. Pulsed optical excitation of the gain medium is achieved by a 450 nm laser diode. The optical feedback for lasing is based on a second-order laterally coupled Bragg grating with a slot-waveguide core. Optimized material gain properties of the organic dye together with the increased modal gain of the laser mode arising from the improved overlap of the slot-waveguide geometry with the gain material enable single-mode lasing at a wavelength of 600 nm. The straightforward integration and operation with a blue laser diode leads to a cost-effective coherent light source for photonic integrated devices.

From 1D to 3D: Fabrication of CH₃NH₃PbI₃ Perovskite Solar Cell Thin Films from (Pyrrolidinium)PbI₃ via Organic Cation Exchange Approach

Energy Technology (2020)

Miao Yu Haochen Fan Pengcheng Wang Yue Zhang Cai‐Yan Gao

A new crystal form of 1D perovskite (pyrrolidinium)PbI 3 (orthorhombic phase) is synthesized and characterized. The 1D perovskite has a good film formability by solution spin coating and is in situ transformed to 3D CH 3 NH 3 PbI 3 via the organic cation exchange approach in CH 3 NH 2 atmosphere, which is dense and uniform. The converted 3D perovskite film is used as a light absorber, and the corresponding perovskite solar cell shows a power conversion efficiency of up to 19.2% under simulated 1 sun AM1.5G illumination (100 mW cm −2 ).

Methylamine-assisted growth of uniaxial-oriented perovskite thin films with millimeter-sized grains

Nature Communications (2020)

Haochen Fan Fengzhu Li Lichang Wang Zhenkun Gu Jin‐Hua Huang

Abstract Defects from grain interiors and boundaries of perovskite films cause significant nonradiative recombination energy loss, and thus perovskite films with controlled crystallinity and large grains is critical for improvement of both photovoltaic performance and stability for perovskite-based solar cells. Here, a methylamine (MA 0 ) gas-assisted crystallization method is developed for fabrication of methylammonium lead iodide (MAPbI 3 ) perovskite films. In the process, the perovskite film is formed via controlled release of MA0 gas molecules from a liquid intermediate phase MAPbI 3 ·xMA 0 . The resulting perovskite film comprises millimeter-sized grains with (110)-uniaxial crystallographic orientation, exhibiting much low trap density, long carrier lifetime, and excellent environmental stability. The corresponding perovskite solar cell exhibits a power conversion efficiency (PCE) of ~ 21.36%, which is among the highest reported for MAPbI 3 -based devices. This method provides important progress towards the fabrication of high-quality perovskite thin films for low-cost, highly efficient and stable perovskite solar cells.

Direct Conversion of CH3NH3PbI3 from Electrodeposited PbO for Highly Efficient Planar Perovskite Solar Cells

Scientific Reports (2015)

Jin‐Hua Huang Ke‐Jian Jiang Xueping Cui Qianqian Zhang Meng Gao

Abstract Organic-inorganic hybrid perovskite materials have recently been identified as a promising light absorber for solar cells. In the efficient solar cells, the perovskite active layer has generally been fabricated by either vapor deposition or two-step sequential deposition process. Herein, electrochemically deposited PbO film is in situ converted into CH 3 NH 3 PbI 3 through solid-state reaction with adjacent CH 3 NH 3 I layer, exhibiting a large-scale flat and uniform thin film with fully substrate coverage. The resultant planar heterojunction photovoltaic device yields a best power conversion efficiency of 14.59% and an average power conversion efficiency of 13.12 ± 1.08% under standard AM 1.5 conditions. This technique affords a facile and environment-friendly method for the fabrication of the perovskite based solar cells with high reproducibility, paving the way for the practical application.
