Solar cell efficiency of perovskite solar cells have increased from 3.8% in 2009 [47] to 25.2% in 2020 in single-junction architectures, [48] and, in silicon-based tandem cells, to 29.1%, [48] exceeding the maximum efficiency achieved in single-junction silicon solar cells.
1954: Invention of the solar battery by Bell Telephone scientists, Calvin Souther Fuller, Daryl Chapin and Gerald Pearson capturing the Sun's power. First practical means of collecting energy from the Sun and turning it into a current of electricity.
"Olympia suitcase", battery-powered portable radio receiver, introduced. The first mobile television camera (180 lines, all-electronic) is used for live television broadcasts of the Olympic Games. Also in the UK are first regular television broadcasts – now for the perfect electronic EMI system, which soon replaced the mechanical part Baird ...
Successive improvements in battery technology facilitated major electrical advances, from early scientific studies to the rise of telegraphs and telephones, eventually leading to portable computers, mobile phones, electric cars, and many other electrical devices. Students and engineers developed several commercially important types of battery.
Solar cells degrade over time and lose their efficiency. Solar cells in extreme climates, such as desert or polar, are more prone to degradation due to exposure to harsh UV light and snow loads respectively. [177] Usually, solar panels are given a lifespan of 25–30 years before they get decommissioned. [178]

The Super Soaker, the Nerf dart guns, my invention on the Galileo spacecraft, the lithium battery technology that I'm developing right now, the solid state batteries as well as the lithium fuel cells.
The timeline begins at the Bronze Age, as it is difficult to give even estimates for the timing of events prior to this, such as of the discovery of counting, natural numbers and arithmetic. To avoid overlap with timeline of historic inventions , the timeline does not list examples of documentation for manufactured substances and devices unless ...
