Sponge-like solar cells could be basis for better pacemakers

Holes help make sponges and English muffins useful (and, in the case of the latter, delicious). Without holes, they wouldn't be flexible enough to bend into small crevices, or to sop up the perfect amount of jam and butter.

Solar cell

A solar cell or photovoltaic cell is a device that converts light directly into electricity by the photovoltaic effect. Sometimes the term solar cell is reserved for devices intended specifically to capture energy from sunlight, while the term photovoltaic cell is used when the light source is unspecified. Assemblies of cells are used to make solar panels, solar modules, or photovoltaic arrays. Photovoltaics is the field of technology and research related to the application of solar cells in producing electricity for practical use. The energy generated this way is an example of solar energy (also called solar power).
