Abstract: A measuring device used to measure a surface of an object is provided. The measuring system includes an air-flow generator, a light emitting device, and a light sensor. The airflow generator is located above the object, and is configured to inject a vapor flow onto the surface of the object and generates a condensing layer on the surface of the object. The light emitting device is located above the object and faces the condensing layer, and is configured to project a light towards the condensing layer. The light sensor is located above the object, and is configured to receive the light scattered by the condensing layer.

Abstract: A surface measurement system is configured to measure a sample with a low reflectivity surface. The surface measurement system includes a condensation device and a measurement device. The condensation device is configured to form a liquid layer on the surface of the sample. The condensation device includes a chamber, a temperature controlling gas source, and a humidification gas source. The chamber is configured to accommodate the sample. The temperature controlling gas source is connected to the chamber to provide temperature controlling gases to the chamber, so as to control the temperature of the sample. The humidification gas source is connected to the chamber to provide water vapor to the chamber, so as to form the liquid layer on the surface of the sample. The measurement device includes a plate, a light source, and an image capturing device.

Abstract: A solar cell testing system includes a multifunctional testing light source, a measuring unit, and an arithmetic unit. The multifunctional testing light source is configured to be switched to output a simulated solar light to a solar cell or asynchronously output a plurality of narrowband lights to the solar cell. The measuring unit is coupled to the solar cell and measures the solar cell's response to the simulated solar light and response to the asynchronously outputted narrowband lights. The arithmetic unit is coupled to the multifunctional testing light source and the measuring unit; it determines the solar cell's conversion efficiency and spectral response based on the solar cell's response to the simulated solar light and response to the asynchronously outputted narrowband lights.

Abstract: An automatic fluorescence detection system includes a base and an optical assembly. The base has a detecting region. The optical assembly includes a fluorescent image-capturing device, an illumination device and a field lens. The illumination device includes a first annular illumination module and a second annular illumination module surrounding a center axis of the fluorescent image-capturing device. Lights emitted by the first annular illumination module and the second annular illumination module travel along a light-traveling path to project onto the detecting region. A distance between the first annular illumination module and the center axis is smaller than that between the second annular illumination module and the center axis. The field lens is disposed in correspondence with the detecting region. Spacing between the field lens and the detecting region is ranged from 15.0 cm to 30.0 cm.

Abstract: A method for inspecting a solar cell and configured to inspect a peeling state of a three-dimensional pattern of the solar cell includes obliquely illuminating the three-dimensional pattern of the solar cell using a light beam. An image of the solar cell is normally captured. An intensity of the light beam is increased to increase a contrast between the three-dimensional pattern and a shadow of the three-dimensional pattern in the image and increase a contrast between an ink pattern of the solar cell and the shadow in the image to overexpose the ink pattern in the image. Determine if the three-dimensional pattern is peeling according to the shadow of the three-dimensional pattern in the image.
