The circuit described here is a 12-V dc to 5-V dc (±5%) switched-mode power supply (SMPS). The supply uses a 12-V input from an array of four 3-V dc, 40-mA solar cells connected in series.

I love all about electronics, circuit diagrams and crazy projects that can help us achieve almost everything our mind can conceive. I created this website and I want to invite you to participate in ...

The solar cells’ output power is monitored by a current- and voltage-measurement circuit (5, 6). A microcontroller (8) controls the measurement and stores the data onto a memory card (9).

Researchers make cyborg cockroaches that carry their own power packs Solar cell and a battery can keep the cyborg's electronics running for weeks.

We predict open-circuit voltages of planar heterojunction solar cells in excellent agreement with experimental data, based only on crystal structures and interfacial orientation.

A Chinese research team has built an all-perovskite tandem solar cell with a 19.6%-efficient wide bandgap top cell relying on a 2D/3D heterostructure and narrow bandgap bottom cell with a 21.3% ...

Let’s see the top 10 electronic circuits and projects for September 2010. As you probably know, we publish this top 10 on monthly bases and we try to show you the most viewed articles on ...
