Abstract: The most fundamental of solar cell characterisation techniques is the measurement of cell efficiency. Standardised testing allows the comparison of devices manufactured at different companies and laboratories with different technologies to be compared. This paper presents a new design of solar cell testers for monocrystalline, polycrystalline, cadmium telluride (CdTe), and copper indium diselenide (CIS) cells. Each cell is tested for efficiency and categorized accordingly into four groups (A to D). A Virtual Reality (VR) model was built to simulate the system, keeping in mind real world constraints. Two photoelectric sensors were used to make detections for both the testing process and the robot movement. A handling robot with vacuum end-effectors was designed based a Modified Interval Type-2 Fuzzy Logic Controller (MIT2FLC) and command line programming for construction, editing, and simulation of the MIT2FLC for control of movement for solar cell and then distributed the cells according to the categories of test for efficiency. The MIT2FLC guides the trajectory of the robot according to the results of the efficiency testing. It was seen that the system worked very well, with the testing process and the robot movement interacting smoothly. The robot trajectory was seen to be highly accurate, and the pick and place operations were done with great precision.
