摘要

A low cost Laser Beam Induced Current (LBIC) system was developed using a Digital Versatile Disc (DVD) laser incorporated in the DVD optical pick-up. This method offers a flexibility to control the laser light focus to get an optimum resolution mapping. The designed system is controlled by using a 32-bit low cost microcontroller integrating a real time operating system in order to offer more flexibility in the control process and the time management. The collect of data and the visualization of the resulting map were done using a developed LabVIEW interface. This paper shows the system design and the experiment process used to obtain the LBIC mapping of realized dye solar cell.
