A while ago I backed the Solar Factory campaign on kickstarter, and I’ve been following the Solar Cells, Fuel Cells, & Batteries course from Stanford, so this article from Spectra-Physics really interested me when I came across it: Manufacturing c-Si Solar Cells with Lasers. It’s a very accessible overview of some manufacturing options to produce solar cells, though it’s obviously still a growing field with a lot of new, interesting research going on.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
