Solar cells capture the energy in light and use it to power the calculator.
A calculator with a small solar panel on it that charges the calculator
the small solar cells on calculators and watches can convert about 12% of the solar energy that lands on them into electricity. A small part, 5%, of the remaining 82% is reflected away by the shiny surface the rest is just lost as heat. The electricity passes directly to the calculator if it is in use, or to the battery if not. if the battery is full then the cells dissiate the energy as heat.

The energy transformation that is in a solar powered calculator is:Device: Solar-powered calculatorInput:Solar energy and Chemical energyOutput: LightThere is 2 ways a Solar-powered calculator is worked by: Solar power and batteries. In the batteries there is chemical. On the solar powered calculator there is a little solar panel. The calculator needs light to power it up. If there is no light the batteries would be it's backup. The numbers are shown by light that the power or batteries and solar power would produce.
