About
Conventional solar panels produce electricity or heat, while demand for each varies with the weather. SolarSkin switches automatically between generating electricity in warm conditions and directing solar heat indoors when temperatures fall. A sealed drop of water changes between vapour and liquid, altering how a lens focuses sunlight onto a photovoltaic cell or a heat-absorbing surface. Requiring no pumps, valves or electronics, this dual-mode system could capture more useful energy from sunlight and reduce reliance on fossil fuels.
