Abstract: A process for producing a sintered AlN ceramic body by mixing an organic solution comprising a hydrocarbon solvent and an organometallic compound with AlN powder to produce a slurry, removing the solvent from the slurry to form a mixture of organometallic compound and AlN, forming the mixture into a shape, and heating the shape in a non-oxidizing atmosphere to sintering temperature to obtain densification.

Abstract: A flexible, photovoltaic panel composed of photovoltaic strips, each strip having a flexible conducting substrate, an amorphous semiconductor body deposited on the substrate, a transparent conductive coating deposited on the semiconductor body, and a current collection grid on the coating, is formed by joining strips along overlapping lengthwise margins with a flexible plastic tape. The tape may contain one or more conducting paths contacting the current collecting grid on an overlapped strip and the substrate of an overlapping strip to electrically interconnect the strips in series. Photovoltaic cells in each strip are electrically connected in parallel, so that interconnected panels may be designed with a wide range of voltage and current outputs.
