Cell performance, or efficiency, η% is the most used, if not most important metric for evaluating different solar cell technologies. Efficiency in turn is determined directly by the product of open-circuit voltage, Voc, short-circuit current density, Jsc, and fill-factor, FF. From numerous studies involving the measurement of η% as a function of stress, it has been determined that η% can be most correlated...
Stability of thin-film CdTe module is crucial to the advancement of the technology. Long-term stability studies are carried out under a variety of accelerated test conditions. Accelerated-life-tests (ALT) are performed in the laboratory to accelerate degradation and hence quantify performance change in reasonably short periods of time. ALT studies attempt to simulate the conditions a solar module...
