Design intelligent solar cell tester system based on microcontroller with handling robot

摘要

The electrical performance of photovoltaic cells is the best parameter for sorting cells, the testing was achieved with the sunlight model. All testers have the common problem of handling the small thin pieces and changing its position from convey tester to storage box and via process. This paper presents an intelligent solar cell tester system with handling robot, controlled by intelligent controller based on microcontroller technique to execute all the required movement for cells through the testing process. The design built for a real solar cell tester has four main types: cadmium telluride (CdTe), copper indium diselenide (CIS), monocrystalline, and polycrystalline. Each type of cell after testing will be distributed according to efficiency to four categories (A-D). Modelling virtual reality (VR) was built for all systems and executed the simulation according to real requirements. Two electric photo sensors are used to implement the sensing of action with a microcontroller; the first for controlling the process of testing and the other for controlling the robot process. The robot's path is controlled by microcontroller according to tester results. Manual controllers were used for speed of conveying information exchange used between the results of tester and microcontroller.
