Abstract:
PURPOSE: A sphere shaped silicon structure based solar cell manufacturing method and a solar cell manufactured using the same are provided to significantly improve productivity by performing a solar cell manufacturing process after mounting a sphere shaped silicon structure on an open groove of an insulating support substrate. CONSTITUTION: A sphere shaped silicon structure in which a first type impurity is doped is mounted on an open groove of an insulating substrate. An intrinsic silicon layer is formed on the sphere shaped silicon structure. A silicon layer in which a second type impurity is doped is formed on the intrinsic silicon layer. A transparent electrode layer is laminated on the silicon layer in which the second type impurity is doped. A front surface reflecting cup is arranged on the substrate. The front surface reflecting cup reflects incident light towards the sphere shaped silicon structure.
Abstract:
The present invention relates to a pest control apparatus. In particular, the self-powered pest control apparatus is formed by adding a self-power supplying function to a pest control apparatus which electrically operates for controlling harmful insects and/or harmful animals. Therefore, the self-powered pest control apparatus can be used without an extra power connection or consumable electric power. According to the present invention, when sunlight is irradiated the pest control apparatus directly receives electric power from a photovoltaic devices. When sunlight is not irradiated, the pest control device receives electric power from a secondary battery in which electric energy is stored. Therefore, the pest control apparatus can be used without relying on external electric power.
Abstract:
A nanoparticle synthesizing apparatus using a line beam laser of the present invention irradiates laser to an inner space of a reaction chamber (20) in a line beam form in which a cross section is a line in order not to be equal to the propagation direction of a reaction gas introduced to the inner space and contains a laser generating device (10) generating line beam at the outside of the reaction chamber (20), thereby being able to use the energy of the laser synthesizing nanoparticles for producing nanoparticles in a scheduled method by being controlled in the inner space of the reaction chamber (20). Especially, the nanoparticle synthesizing apparatus prevents the generation of reaction gas incapable of reacting with a laser through a line beam, thereby greatly improving mass production technology efficiency of nanoparticles.
