To evaluate the outdoor performance and stability of perovskite solar cells using contactless and noninvasive methods, an Australian and Chinese research team found a way to use photoluminescence ...

Scientists at Germany's Fraunhofer Institute for Solar Energy Systems ISE have demonstrated a triple-junction solar cell with a perovskite-perovskite-silicon subcell configuration. They said the cell ...

In an earlier article, I covered Fire Hazard Tests that form an important part of safety testing for electronic/electrical products. We looked at the standards and equipment used for abnormal heat, ...

Suppose that you need to test a 1.5V, AA-size alkaline battery. You can apply a short circuit and measure current, or you can measure open-circuit voltage, but neither method properly tests the ...

BGE reviews several alternatives for a battery open-circuit monitoring device to protect from a dc supply single point of failure. The Federal Energy Regulatory Commission issued Order 867 on Jan. 23, ...

Table 100.19 from ANSI/NETA MTS-2011 provides recommended test voltages for proof testing and field testing medium-voltage power circuit breakers and switchgear. These three tests should be in your ...

Voltage transformers (VT) are used in electrical grids for metering and/or protection purposes. The high requirements regarding their precision demand a calibration ...
