Solar simulator for the characterization of photodetectors and solar cells

摘要

Low cost solar simulator (1) for the characterization of photodetectors and solar cells, characterized in that it comprises: a) a frame (2) of essentially parallelepiped shape that is formed by: - a sample module (21) to receive a photodetector or solar cell sample supported on a sample holder (6), - a lighting module (22) attachable to the sample module (21), where the lighting module (22) comprises a first horizontal receiving slot (221), - a power module (23) formed by four vertical columns whose lower end is attachable to the corners of the lighting module (22), where interior faces of the vertical columns comprise a second horizontal receiving slot (231), and - a control module (24) attachable to upper ends of the vertical columns of the power module (23), where the control module (24) comprises a third horizontal receiving slot (241); b) a first electronic board (3) housed in the first horizontal receiving slot (221), where the first electronic board (3) comprises a panel of LEDs oriented vertically downwards; c) a second electronic board (4) housed in the second horizontal receiving slot (231) and electrically connected to the first electronic board (3), where the second electronic board (4) comprises power electronics for driving the LEDs of the first electronic board (2); and d) a third electronic board (5) housed in the third horizontal receiving slot (241) and connected to the second electronic board (4) and to a user interface, where the third electronic board (5) comprises control electronics to control LEDs function according to user requirements.
