    摘要: A speckle contrast reducing method for a laser scanning projection system includes the following steps. Firstly, a laser beam is provided. The laser beam is projected on a projection surface according to a first scanning trajectory, thereby generating a first image frame. Sequentially, the laser beam is projected on the projection surface according to a second scanning trajectory, thereby generating a second image frame at an image refresh rate. Moreover, the second scanning trajectory of the second image frame is shifted by a displacement from the first scanning trajectory of the first image frame along a slow-axis direction.

    摘要: A thin film silicon solar cell and a manufacturing method thereof. The thin film silicon solar cell comprises a glass substrate, a first electrode layer, a light absorbing layer, a second electrode layer, and a metal electrode layer sequentially stacked on top of one another. The second electrode layer has a texture surface and concavities formed on the texture surface, and each of the concavities has a width falling within a range of 100 nm-1600 nm and a depth less than 800 nm.
