Method for manufacturing solar cells

摘要

The lava stone can be sawed and drilled and no particularly high-quality tool (HSS) is required for this. The liquid magma can be directed directly into casting dies or casting moulds. The connections either cast with them or copper pins can be placed in them. Since the lava stone is a galvanic element there are no insulation problems. A plurality of connections can be inserted into the same shape of lava stone. Then, the lava stone is also used as a coil former. The coil is induced. Application is possible as an ignition coil in a motor vehicle. The core is charged via the lava solar cell on the roof of the vehicle. As a roof cover, it can be drilled and screwed or nailed with cramps. In this way heat insulation, a heat accumulator and a power generator are obtained at the same time. As a battery in a car there are again no insulation and electric shock problems and likewise as a solar cell on the roof of a motor vehicle, the battery would then be dispensed with. As a capacitor there are no electric shock problems since in all areas of application costly insulations are dispensed with. The invention is extremely suitable as a heat accumulator for heating systems, heat pumps, hot water (throughout the year), insulating pots etc. There is therefore hardly any area in which lava stone cannot be used.
