The difference is almost trivial, but there is one difference
There are also chips in photovoltaic systems
Photovoltaic, short for solar photovoltaic power generation system, is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert sunlight radiation into electrical energy.
Chips, also known as integrated circuits, or microcircuits, microchip chips in electronics are a way of miniaturizing circuits (mainly semiconductor devices, but also passive components, etc.) and are often manufactured on the surface of semiconductor wafers
