Lighting a string of LEDs at a constant brightness requires driving it with a regulated current. A boost converter is commonly used to step up the voltage to a level high enough to bias the LEDs on ...

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 ...

JA Solar announced it achieved a record-breaking open-circuit voltage for a solar cell based on tunnel oxide passivated contact (TOPCon) technology. Germany's Institute for Solar Energy Research in ...

[Hales] has been on a mission for a while to make his own diodes and put them to use and now he’s succeeded with diodes made of sodium bicarbonate and water, aluminum tape and soldered copper. By ...

The future is growing brighter for lighting based on lightemitting diodes (LEDs), thanks in part to falling prices and global government mandates to reduce energy consumption. High brightness LEDs are ...

Diodes whose reverse-breakdown characteristics are controlled precisely during manufacture are called as Zener diodes and are intended specifically for operation in the reverse breakdown mode ...
