And solves a known problem: Concentration of light increases heat, which decreases the production of electrical energy in PV. Current solar power theory estimates that a square meter of sunlight has a maximum energy content of 1,000 watts. Based on this, a 20% efficient photovoltaic (PV) panel should produce 200 watts of energy from one square meter of sunlight. Through its unique patent pending design, V3Solar’s Spin Cell is able to concentrate 20X more sunlight on the same type of PV that is commonly used in standard solar panels without them overheating. This is achieved through a combination of solar concentrating lenses and unique thermal management. The Spin Cell concentrates the light and avoids the heat. Light is transferred to electricity in nanoseconds. Heat is transferred in milliseconds (1000X longer). The PV on the Spin Cell captures the light, generates the electrical energy and then spins away avoiding heat build up in the PV. The V3solar patent pending design also delivers a higher level of efficiency from PV. Tests to date have shown improvements under laboratory conditions of around 30%, which effectively lifts the efficiency of the PV. This means that the PV is able to convert a higher proportion of the light hitting it into energy without having to use more expensive, high efficiency PV. With existing flat panel technology using 20% efficient PV, 5 square meters of PV material and 5 square meters of light is required to produce 1000 watts of electricity. With 30% efficient PV, approximately 3.3 square meters of light and PV material is required."
