Abstract:
A thin film solar cell and process for forming the same. The solar cell includes a bottom electrode, semiconductor light absorbing layer, and top electrode. Interconnects may be formed between the top and bottom electrodes by electrochemical plating of conductive materials in recessed regions formed between the electrodes. In some embodiments, the conductive materials may be optically opaque metals having non-light transmissive properties. The interconnects are highly conductive and minimize the thickness of the top electrode layer, thereby enhancing light transmission and cell energy conversion performance.

The major characteristic of the present invention lies in the adoption of electromagnetic means to translate the spin of a wheel module into continuous electrical signals. A permanent magnet is incorporated in the wheel module to provide magnetic field. Two sensors tangential to the spinning direction of the permanent magnet are used to detect the variations of the magnetic field from the spin of the wheel module in accordance with the Hall Effect.

A method for automatically changing caption display style based on program content is disclosed. Plural caption parameters for each program content type are pre-defined. When a TV program is switched, a program system information protocol (PSIP) is searched to confirm program content type of the TV program. Captions of the TV program are decoded using a caption decoder based on program content type and corresponding caption parameters and the captions of the TV program are displayed according to the caption parameters relating to the program content type.

A solar cell with a molybdenum back electrode layer and a molybdenum selenide ohmic contact layer over the molybdenum back electrode, is provided. The molybdenum selenide layer includes an accurately controlled thickness. A distinct interface exists between the molybdenum back electrode layer and the molybdenum silicide layer. The molybdenum silicide layer is produced by forming a molybdenum layer or a molybdenum nitride layer or a molybdenum oxide layer over an initially formed molybdenum layer such that an interface exists between the two layers. A selenization and sulfurization process is carried out to selectively convert the molybdenum-containing layer to molybdenum selenide but not the original molybdenum back electrode layer which remains as a molybdenum layer.
