A Study of Texturing on the Surface of Advanced Multi-Crystalline Silicon Solar Cell
With the traditional energy sources gradually depleting, solar energy represented as a kind of new alternative energy, has received more and more attention for its clear, non-pollutant and inexhaustible functions. While compared with traditional energy, solar energy faces significant technological and economic challenges due to the cost and complexity, and restricts its further application. In this paper, a new approach is present by using orthogonal ultrasonic standing wave with acid mixture to texture the surface of multi-crystalline silicon (mc-Si). Then the well-shaped grid is formed to control the mixed acid molecules distribution, and the surface of mc-Si is etched. SEM experiment illustrates the molecules movement and chemical etching are both controlled by orthogonal ultrasonic standing wave.
