Solar powered calculator

Solar powered calculators are hand-held electronic calculators powered by photovoltaic panels mounted on the device.[1] They were introduced at the end of the 1970s.[2]

Features

Solar calculators' displays utilize vacuum fluorescent displays as they are power efficient and is capable of operating in the low voltage range of 1.5 - 2 V.[3] Features on other models includes a light pipe used to converge light onto the solar cells to power the calculator.[4]
