    en.wikipedia.org/wiki/Solar-powered_calculator

    Solar-powered calculators are hand-held electronic calculators powered by solar cells mounted on the device. [1] They were introduced at the end of the 1970s. [2]Amorphous silicon has been used as a photovoltaic solar cell material for devices which require very little power, such as pocket calculators, because their lower performance compared to conventional crystalline silicon solar cells is ...

    The largest manufacturers of solar equipment were based in China. [64] [65] Although concentrated solar power capacity grew more than tenfold, it remained a tiny proportion of the total, [66]: 51 because the cost of utility-scale solar PV fell by 85% between 2010 and 2020, while CSP costs only fell 68% in the same timeframe. [67]
