The
EL-8026 was the world’s first calculator using solar cells instead of
batteries. The power consumption of the calculator was higher and the efficiency
of the solar cells lower than today. Sharp covered the whole backside of this
calculator with solar cells to get enough power from the sun.
It took 5 years before Texas Instruments entered with the TI-1766 the market of LCD-calculators powered by solar cells
One year later Sharp introduced with the EL-8130
the touch keyboard. Overall thickness of the calculator was only 0.2 inches.
