Abstract:
A window blind is disclosed. The window blind includes a slat having a convex curved surface. The window blind also includes a solar cell module having solar cells and being attached to the convex curved surface of the slat. The carrier generating portions of the solar cells are made of a thin film group III-V compound semiconductor that can be bent, so that the solar cells can be attached to the convex curved surface. The length of the curved surface of the solar cell module in the longitudinal direction is at least half the length of the curved surface of the slat in the longitudinal direction. The solar cell module is disposed eccentrically to one side with respect to the transverse centerline of the slat.
Abstract:
A solar cell module having flexibility is disclosed. The solar cell module includes a first solar cell and a second solar cell disposed adjacent to each other. The solar cell module also includes an interconnector disposed between the first and second solar cells, and configured to serially connect the first and second solar cells with each other. Each of the first and second solar cells includes: a flexible substrate, a lower electrode formed on the flexible substrate, a III-V group compound semiconductor partially formed on the lower electrode such that a partial region of the lower electrode is exposed to outside, and an upper electrode formed on the III-V group compound semiconductor. The interconnector is disposed to cover a space between the first and second solar cells, and is electrically connected to the lower electrode of the first solar cell and the upper electrode of the second solar cell.
Abstract:
Disclosed are phosphors and, more particularly, yellow light emitting phosphors and light emitting device packages using the same. The yellow light emitting phosphor includes a first phosphor to emit light having a central wavelength located within a band of 510 nm to 550 nm, a second phosphor adapted to be mixed with the first phosphor to emit light having a central wavelength located within a band of 560 nm to 600 nm, and a third phosphor adapted to be mixed with the first and second phosphors to emit light having a central wavelength located within a band of 610 nm to 630 nm, the third phosphor having a light absorption rate of 50% or less at a wavelength of 550 nm.
