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 ...

Researchers from Pakistan's Ghulam Ishaq Khan Institute of Engineering Sciences and Technology have created an online algorithm to measure open-circuit voltage in PV systems that is claimed to be able ...

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, ...

Researchers from Canada have developed solar cells that boast a record-breaking open circuit voltage. The solar cell design features indium gallium phosphide (InGaP), indium gallium arsenide (InGaAs), ...

Using colloidal lead sulfide nanocrystal quantum dot substances, researchers have achieved the highest recorded open-circuit voltages for quantum dot solar cells to date. U.S. Naval Research ...

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 ...

The digital voltmeter is the best basic tool for electrical troubleshooting, because it's calibrated and exact. But remember, the digital voltmeter can't detect a high-resistance fault if the circuit ...
