Perovskite Tandem Solar Cell IV Tester with Specialized MPPT Control
Perovskite and tandem solar cells require careful electrical characterization. Their I-V response may be affected by hysteresis, changes in device state, and movement of the maximum power point. A suitable perovskite tandem solar cell IV tester should therefore be evaluated not only by its ability to measure current and voltage, but also by how its testing and control methods address the behavior of the device. Why is MPPT important? Maximum Power Point Tracking identifies and follows the operating point where a photovoltaic device delivers maximum power under the specified conditions. For emerging solar cell technologies, tracking stability and the ability to respond to device dynamics are important considerations when evaluating test equipment. Yoha Solar's technical development Yoha Solar has announced a dedicated MPPT control system for perovskite and tandem cell I-V testing. The development addresses challenges associated with I-V hysteresis and maximum power point insta...
