摘要： A photoelectric conversion device includes a front electrode, a photoelectric conversion layer formed of a semiconductor material, a transparent conductive layer formed of a transparent conductive oxide, a back electrode formed of a metal material, and a conductive layer formed of a semiconductor material primarily of silicon and having a refractive index higher than the transparent conductive layer contactually sandwiched between the transparent conductive layer and the back electrode. The photoelectric conversion device exhibits a high photoelectric conversion efficiency by keeping low the electrical resistance between the semiconductor layer and the back electrode and by increasing reflectance for light having passed though the semiconductor layer.

摘要： To provide a solar cell that reduces occurrence of a defect and has high photoelectric conversion efficiency. The solar cell includes a silicon substrate such as an n-type single-crystal silicon substrate single crystal with pyramid-shaped irregularities P formed thereon, and an amorphous or microcrystal semiconductor layer formed on the single-crystal silicon substrate. A flat part F is formed in a valley portion of the pyramid-shaped irregularities P provided on a surface of the single-crystal silicon substrate. With this configuration, a steep angle of 70° to 85° of a concave portion formed by a substantially (111) surface can be widened to between 115° and 135°. Accordingly, a change of atomic step morphology attributable to a rounded shape can be eliminated, thereby enabling to reduce epitaxial growth and defects in the amorphous or microcrystal semiconductor layer.

摘要： A current supply circuit includes a bit select circuit selectively providing even-numbered bits or odd-numbered bits of eight bit image data, and supplies a gray-scale current corresponding to the bits provided from the bit select circuit to a pixel. In a one-frame period, a time length for supplying a current corresponding to the even-numbered bits to the light-emitting element is set twice as large as a time length for supplying a current corresponding to the odd-numbered bits. By setting 16 levels of the gray-scale current for four bits, a current-time product of a current passing through the light-emitting element during the one-frame period can be controlled to 256 levels for eight bits. Thereby, an image display device provided at each of the pixels with the light-emitting element can reduce sizes of circuits generating the gray-scale current in accordance with a digital signal.

摘要： A method for manufacturing a thin-film semiconductor includes polycrystallization to focus visible light pulse laser into a line shape on a surface of an object to be irradiated, and repeat irradiation with displacing the visible light pulse laser such that a line-shaped irradiated region is overlapped with a region irradiated at a next timing in a width direction of the line-shaped irradiated region, to form a polycrystalline silicon film on the surface of the object. The step of polycrystallization applies ultraviolet light pulse laser onto a second irradiated region partially overlapping the first irradiated region while or before the visible light pulse laser is applied to the first irradiated region.

摘要： A current supply circuit providing a data line with a current corresponding to a digital signal composed of data bits includes a current control circuit, a precharge switch and a precharge regulating circuit. The current control circuit responds to control signal reflecting respective data bits to control the amount of current along the data line (DL). The precharge switch precharges the data line to a predetermined voltage prior to current supply. The precharge regulating circuit exchanges with the data line electric charge corresponding to the control signals to move the voltage on the data line closer to a steady voltage corresponding to the data bits. In this way, an analog current corresponding to digital data can be promptly produced.
