    High-Efficiency Synthesis of N,N ’ -Diacetyl-β-Chitobiosyl

    The high-efficiency synthesis of N,N’-diacetyl-β-chitobiosyl allosamizoline 2 was investigated. The Nbenzyloxycarbonyl (Cbz) protected trichloroacetimidate donors 11 and 13 were synthesized by routine method. The solidphase synthesis was performed using polystyrene as support and o-nitrobenzyl ether tether as linker.

    A Supramolecular Radical Dimer: High‐Efficiency NIR‐II Photothermal

    The supramolecular radical dimer (2MPT.+ ‐CB[8]) showed highly efficient photothermal conversion and improved stability, thus contributing to the strong inhibition on HegG2 cancer cell under 1064 nm irradiation even penetrating through chicken breast tissue. This work provides a novel approach to construct NIR‐II chromophore by tailor

    This results in long minority carrier bulk diffusion lengths. 4.2. Efficient back-surface field The BSF obtained in this process is very efficient and shields the minor- ity carriers from the ohmic contact at the back side of the cell. Together with the long bulk lifetimes it provides a high collection efficiency. 4.3.

    Abstract: The present work overcomes the reported gap of the past years by disclosing the development of high-efficiency silicon solar cells fabricated on large-area (50 mm) nwafers. The distinctive trait of developed cells is their extremely large short-circuit current density Jsc under AMl conditions (100 mW/cm2 insolation).

    The design and fabrication of high‐efficiency p + ‐n‐n + back‐surface‐field silicon solar cells are described. The fabrication process has been developed to yield maximum attainable carrier lifetimes (∼0.7 msec) in the base region of the cell, thereby allowing the back n‐n + junction to effectively enhance the cell performance.

    High efficiency white organic light emitting diodes using Rubrene doped

    1. Introduction. OLEDs are quite promising for the next generation of flat panel displays since Tang and Vanslyke demonstrated efficient thin film electroluminescence (EL) devices driven by a low direct current (dc) voltage because of their excellent properties such as low driving voltage, high efficiency, lightweight, thinness, and bright emission , .
