摘要:
A zinc oxide (ZnO) film is fabricated. Metal-organic chemical vapor deposition (MOCVD) is used to obtain the film with few defects, high integrity and low cost through an easy procedure. The ZnO film above a silicon substrate has a matching crystal orientation to the substrate. Thus, the ZnO film is fit for ultraviolet light-emitting diodes (UV LED), solar cells and related laser devices.

A photovoltaic system able to float on water and track sun includes a floating mechanism; an adjusting mechanism, combining with the floating mechanism; and a solar power mechanism, combining with the adjusting mechanism and located above the floating mechanism. This photovoltaic system can be located on the water surface, and has its floating mechanism to be under water by using the adjusting mechanism and the surrounding water source. The adjusting mechanism can be further used to adjust the solar power mechanism to a specific tilt angle according to the water level of the surrounding water and the sun-tracking angles that varies as the locations of the sun. Therefore, a novel photovoltaic system with simplified configuration, accurate sun tracking and enhanced power generation efficiency can be achieved.

In a method for making a full-spectrum solar cell, there is provided an ordinary solar cell with an anti-reflection layer. The anti-reflection layer is coated with a film of silicon nitride and/or silicon oxide. The silicon/nitrogen ratio and/or the silicon/oxygen ratio and the temperature are regulated, thus forming a silicon-rich film via doping the anti-reflection layer with silicon from the film of silicon nitride and/or silicon oxide. The precipitation of the silicon in the silicon-rich film is executed based on a mechanism of phase separation, thus forming silicon quantum dots of various sizes in the anti-reflection layer.
