Delivery Record: Information and Image Processing Equipment for Solar Cell Characterization and Evaluation System
Measuring the characteristics of solar cells without destroying the solar cell module.
The solar cell evaluation device is a device that can measure the characteristics of individual solar cells without destroying the solar cell module in a non-contact manner. Traditionally, the evaluation of solar cells was conducted by irradiating the solar cells with simulated sunlight (solar simulator) and measuring the electrical characteristics produced. While this method allows for understanding the characteristics of the entire solar cell module, it does not provide information on the characteristics of each cell that makes up the module. This device utilizes the electroluminescence (EL) effect of semiconductors, enabling the high-speed measurement of electrical characteristics for each cell. The production volume of solar cells continues to grow at a high rate of 30-40% annually, increasing expectations for this device. 【Features】 - Measures the characteristics of solar cell cells without destroying the solar cell module - Non-contact evaluation device - Utilizes the electroluminescence (EL) effect of semiconductors - Capable of high-speed measurement of electrical characteristics for each cell *For more details, please refer to the PDF document or feel free to contact us.

Company information
★ Both electrical design and mechanical design are supported, and the company continues to expand smoothly, with annual sales projected to increase from 9.7 billion yen last year to 12.5 billion yen this year (with the fiscal year ending this month). We have a total of 70 technical staff involved in various software designs such as measurement and control circuit design, image processing, mechatronics line design, and related peripheral designs, and the number of employees has exceeded 540. ★ Not only design but also sheet metal processing, machining, surface mounting, assembly, and inspection are in-house processes, ensuring short delivery times and high quality. In particular, we have equipment capable of handling large boards (500×600) and high-density boards (BGA, 0.5mm QFP) for circuit board assembly, and in the inspection process, we have equipment such as X-ray inspection machines and in-circuit testers. Additionally, we have renewed our equipment mainly at the Kumamoto, Hamamatsu, and Sagamihara factories. ★ In January 2015, we established the Sagamihara Division in addition to the Kyoto, Kumamoto, and Hamamatsu factories, creating a four-division structure, and in March 2016, new buildings began operations at the Kyoto and Kumamoto factories.
