Three kinds of cluster photovoltaic systems are provided, comprising: a common cluster photovoltaic system established by a photovoltaic circuit and a cluster photocell which is irradiated by lights directly; a direct cluster photovoltaic system established by a photovoltaic circuit and a cluster photocell which is irradiated by the lights gathered by a refraction convex lens or a reflection concave mirror; and a transmission cluster photovoltaic system established by a photovoltaic circuit and a cluster photocell which is irradiated by lights that are gathered by a refraction convex lens or a reflection concave mirror and then transmitted in curve for a certain distance in a transmission optical fiber. The key portion of the cluster photocell is PN junction which can be formed by coating a very thin negative type layer on the surface of a thin sheet of P-type silicon mono-ordered crystal with the thickness of 0.3-0.5mm, using the diffusion method to form a N-type layer for example. After that, the cluster photocell is formed by adding an electrode on each side of the PN junction respectively. When the cluster photocell is irradiated by lights, voltage and current will be generated between the two electrodes. The discovery of the cluster exposes the essence of mesocopy matter. |
