A photocell converts light energy (radiant electromagnetic energy to be precise) into electrical energy.
A thermocouple can convert heat into electrical energy.
The radiant em conversion yields much more energy than a heat conversion.
In a candle, the heat energy produced by the burning wax is converted to light energy and heat energy. This conversion is not an efficient process and does not directly produce electric energy. However, the light energy emitted by the candle can be converted to electric energy through technologies like solar panels that capture sunlight.
Examples of energy conversions include: Chemical energy in food being converted to mechanical energy in muscles during physical activity Solar energy being converted to electrical energy in solar panels Electrical energy being converted to light energy in light bulbs
In a solar panel, sunlight is absorbed by photovoltaic cells, which convert the light energy into electrical energy through the photovoltaic effect. This process involves the conversion of photons from the sunlight into electrons, creating an electric current that can be used as a source of power.
One example of converting light energy to electrical energy is through the use of photovoltaic cells in solar panels. When sunlight hits the cells, it generates an electric current through the photovoltaic effect, allowing the light energy to be converted into usable electrical energy.
light to electricity to light (plus that old devil heat).

No. It's usually the other way around. Solar = from the sun, and we can't recharge the sun. Turning electric energy into light OTOH happens in every lightbulb.
In short, the light (electromagnetic energy) shining on the solar cell is converted directly to electric charge (potential energy). The increase in the electric charge can promote the flow of electric current in an external circuit, in much the same way as an ordinary electrical battery would.

A solar power calculator harnesses solar energy from light, which is converted into electrical energy by the solar panel on the calculator. This electrical energy is then used to power the calculator.
Solar panels generate energy through the photovoltaic effect, where sunlight is converted into electricity. When sunlight hits the solar panels, the photons in the light excite electrons in the panels, creating an electric current. This electricity can then be used to power homes, businesses, and other devices.
