摘要： A solid type dye-sensitized photoelectric conversion element which is excellent in photoelectric conversion efficiency and which can be manufactured at a low cost is disclosed. The photoelectric conversion element can be applied to a so-called wet type solar cell which does not use any electrolyte. The solar cell comprises a first electrode 3, a second electrode 6 arranged opposite to the first electrode 3, an electron transport layer 4 arranged between the first electrode 3 and the second electrode 6, a dye layer D which is in contact with the electron transport layer 4, a hole transport layer 5 arranged between the electron transport layer 4 and the second electrode 6 and being in contact with the dye layer D, and a barrier layer 8, and these elements are provided on a substrate 2. The barrier layer 8 constitutes short-circuit preventing or suppressing means for preventing or suppressing short-circuit between the first electrode 3 and the hole transport layer 5. The porosity of the barrier layer is made smaller than that of the electron transport layer 4. The barrier layer is formed into a film-like shape and arranged between the fist electrode 4 and the electron transport layer 4. The solar cell can accomplish excellent photoelectric conversion efficiency by the provision of such a barrier layer 8.

摘要： A conventional dye-sensitized solar cell is a wet cell employing an electrolyte such as an iodine solution or the like, it is necessary to seal the solar cell with a sealing compound or the like in order to contain the iodine solution therein. Therefore, there are many problems in that, for example, leakage of electrolyte solution occurs when the sealing is broken. Furthermore, when only a flat-shaped titanium electrode is used, current and voltage of practically required levels can not be secured because the absorption area of solar rays is small. The solar cell of the present invention, employing a porous titanium dioxide semiconductor, is characterized in that the titanium dioxide semiconductor is held between a pair of electrodes so that the titanium dioxide semiconductor and at least one of the electrodes form a rectification barrier.

摘要： Conventional dye-sensitization solar cell are of a wet type including an electrolyte such as an iodine solution, and therefore the electrolyte must be sealed in the solar cell with a sealant, involving drawbacks such as electrolyte leak when the sealing ruptures. Further if merely a titanium sheet is used, the sunlight absorption area is small, failing to ensure a practical current and voltage. A solar cell according to the invention made of titanium dioxide (TiO2) semiconductor is characterized in that the titanium dioxide is sandwiched between a pair of electrodes and the titanium dioxide semiconductor and at least one of the paired electrodes serve as a rectifying barrier.

摘要： PROBLEM TO BE SOLVED: To solve the problem in which: a piezoelectric motor brings a protrusion into contact with a lateral surface of a rotating body and drives the rotating body; and, accordingly, a current flowing through a piezoelectric element is distorted by reaction force at the time of contact.SOLUTION: A piezoelectric motor comprises: a rotating body; a piezoelectric actuator that has a protrusion brought into contact with the rotating body and rotates the rotating body by motion of the protrusion when a piezoelectric element is driven; and a driving circuit for driving the piezoelectric element. The driving circuit includes: a driving signal generating section for outputting a driving signal having a predetermined frequency; and an LC filter for cutting off a frequency higher than the predetermined frequency. The driving circuit applies the driving signal to the piezoelectric element via the LC filter.
