DC-DC converter starts up and operates from a single photocell
by Marian Stofka @ www.edn.com: The bq25504 from Texas Instruments is a good candidate to become a milestone on the road to micro-power management and energy harvesting. A prominent feature of this IC is its ability to start up at a supply voltage as low as 330 mV typically, and 450...

Grid-connected solar microinverter reference design
A PDF from Microchip on the theory behind inverter design connected to grip power.: There are two main requirements for solar inverter systems: harvest available energy from the PV panel and inject a sinusoidal current into the grid in phase with the grid voltage. In order to harvest...

Bismuth Oxyiodide (BiOI)—A Non-toxic Alternative To Solar Cells
Bismuth is considered as a "green-element" and bismuth-based compounds are gaining attention as potentially non-toxic and defect-tolerant solar absorbers. The researchers of the University of Cambridge and the United States developed theoretical and experimental methods to show that...

MPPT solar charger
Lukas Fässler from Soldernerd has been working on revised version of his MPPT Solar charger project: Over the last few weeks I have been quite busy with my MPPT Solar Charger project. I’ve built up a first board and started writing firmware for it. Since the last version was not...
