IPC: H01L51/40
Filed: 1993-09-29
Abstract: PURPOSE:To enhance the energy conversion efficiency through combination of an organic n-type semiconductor comprising a specified fluorinated vanadylphthalocyanine and an organic p type semiconductor. CONSTITUTION:Fluorinated vanadylphthalocyanine shown by a formula [in the formula, sixteen Xs represents halogen atoms and twelve or more of them represent fluorine atoms and the remainder represent chlorine or bromine atom] is deposited thinly on a conductive substrate to produce a wet organic solar cell. A thin film of fluorinated phthalocyanine is deposited, by vacuum deposition, on a conductive substrate of indium oxide doped with tin or tin oxide doped with fluorine and then it is immersed into an electrolytic solution of iodine/potassium iodide with a platinum counter electrode being provided. Since electron absorptive fluorine atoms are introduced for phthalocyanine, n-type semiconductor characteristics are obtained while sustaining high sublimation performance. Furthermore, conversion effeiciency can be enhanced by orienting the fluorinated phthalocyanine.

Filed: 1996-09-13
Abstract: PROBLEM TO BE SOLVED: To provide a method of monitoring a heat-exchange of a wire-saw with the capability of positively detecting a foul state of the heat-exchanger. SOLUTION: When the heat-exchanger 42 is in a normal state, slurry (wording liquid) 36 passed through the heat-exchanger 42 is cooled to a predetermined temperature after the heat-exchange done by the heat-exchanger 42. However, in the event when any abnormality exists in the heat-exchanger 42, the temperature of the slurry 36 to be outputted becomes higher than in a normal state. On the basis of this, the slurry 36 at a predetermined temperature and a predetermined flow rate is passed through the heat-exchanger 42 for measuring the temperature of the slurry 36 before and after the heat-exchanger. When the difference between the temperatures is lower than a reference value set previously, the heat-exchanger 42 is determined as being abnormal. Thus, a proper timing of cleaning and inspection can be determined for the heat-exchanger 42.

Abstract: PURPOSE:To form a reaction chamber narrower than a wafer diameter, reduce the occupied space, and cut down the occupied floor area of a total equipment, by constituting electrodes of the reaction chamber to be the vertically protruding type. CONSTITUTION:A wafer carrier 12 accommodating wafers 13 is arranged in a preliminary chamber 11, which is vacuumized by a vacuum exhaust pipe 19.
