Abstract: The present invention is a photosensitized electrode which absorbs sunlight to obtain electron-hole pair. The photosensitized electrode is fabricated with simple procedure and has low cost. The electrode has excellent chemical resist to be applied in a solar cell device with enhanced sun-light absorbing ability. The present invention can be applied in an optoelectronic device or a hydrogen generator device too.

Abstract: A concentration photovoltaic cell system with light guide includes a concentrator for focusing sunlight; a light guide located at where the sunlight is focused by the concentrator, so that the focused light is fully coupled to an input end of the light guide and propagates to an output end of the light guide; and a solar energy converter arranged at the output end of the light guide for receiving and converting the light projected from the light guide into electric energy. With the above arrangements, the solar converter may be located at a place not exposed to sunlight to avoid lowered energy conversion efficiency caused by temperature rising at photovoltaic cell chips thereof, and the use of the light guide enables increased GCR and light concentrating efficiency to enable reduced number of expensive photovoltaic cells.

Abstract: A concentrating photovoltaic (CPV) apparatus includes at least one lens unit, at least one solar cell chip unit, and a frame structure. The frame structure includes at least two opposite main walls, a plurality of upper and lower support bars extended between and connected to the two main walls, and two sidewalls. The main walls are each provided with at a predetermined position with at least one air opening and at two lateral ends with a first and a second connecting portion. Two ends of the upper and lower support bars are connected to the first and the second connecting portions, allowing the lens unit and the solar cell chip unit to be supported on and fixed to the upper and the lower support bars, respectively.

Abstract: In a method of forming a concentration solar cell chip packaging structure, at least one solar cell chip is mounted on an electrically conducting plate, and the solar cell chip along with the conducting plate are encapsulated in a package made of a highly light-pervious and shock-absorbing polymer material. Moreover, a thin layer of low-iron, high-strength, and light-pervious material is attached to an outer surface of the polymer package. With the above method, the concentration solar cell chip packaging structure may be formed with shortened processing time and improved processing quality to give the packaged solar cell increased light transmittance and prolonged usable life.
