Exploring Solar Panel Efficiency Breakthroughs in 2022

In May NREL set a new benchmark for solar panel efficiency. Solar power is one of the most readily available renewable resources out there, if you can harness it. These new cells aren’t just impressive for their efficiency but how little light intensity was required.

Details of the development are outlined in the paper “Triple-junction solar cells with 39.5% terrestrial and 34.2% space efficiency enabled by thick quantum well superlattices,” which appears in the May issue of the journal Joule.

The results come from Inverted Metamorphic Multi-junciton cells. Great recap of current solar panel tech from Undecided with Matt Ferrell:

Scientists have just had a major solar panels efficiency breakthrough, and it could mean a big change for the future of renewable energy.


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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
