Application: Solar Cell Testing
Solar cells convert light energy directly into electricity by photovoltaic effect. Assemblies of cells make up solar modules used to capture sunlight for conversion to electrical power. Cells can be described as photovoltaic cells even if the light source is not necessarily sunlight. While connecting cells in parallel yields increased current, significant problems exist with such arrangements. To yield practical use, generated electricity is most often fed into the grid using inverters. In stand-alone systems, batteries store energy that is not used immediately. Solar panels can be used to power or recharge portable devices.
One solar cell testing system uses a pulsed Xeon lamp as a simulated photo source, to achieve uniformity of simulated sunlight with no influence of temperature interference. The light spectrum meets IEC 60904-9 and JISC8933 standards. 10 test parameters observed include Isc, Voc, Pmax, Vm, Im, FF, EFF, Temp, Rs and Rsh. Testing software can display the I-V curve of the interface and automatically record the test parameters of all modules to verify solar cell quality.
ADLINK Solution: DAQ-2010: 4-CH 16-Bit Up to 2 MS/s Simultaneous-Sampling Multi-Function DAQ Card
The ADLINIK DAQ-2010 is a simultaneous-sampling multifunction DAQ module, suited to a wide range of application requirements. The module can simultaneously sample 4 AI channels with differential input configuration, achieving maximum noise elimination. Also provided are 2-CH 12-Bit analog outputs with waveform generation capability performable with analog input functions. If more analog input or output channels are required, multiple modules can be synchronized through the SSI (system synchronization interface) bus. The DAQ-2010 also features analog and digital triggering, 24-CH programmable digital I/O lines, and 2- CH 16-Bit general-purpose timer/counters
