Dual-grating structure thin-film silicon solar cells with different front and back grating periodicities are designed The geometrical parameters of both gratings are investigated. The reflection is greatly reduced by ...
An efficient 1 319-nm Nd:YAG single-frequency laser is demonstrated in a diffusion-bonded nonplanar ring oscillator (NPRO) with an undoped end. The thermal model of diffusion-bonded NPRO is generated to analyze the...
