Abstract: The invention relates to a variable-spectrum solar simulator for characterising photovoltaic systems. The simulator can be used to obtain a spectrum adjusted to the solar spectrum, both for a standard spectrum or a real spectrum adjusted to local irradiation conditions. The simulator also allows the spatial-angular characteristics of the sun to be reproduced. The invention comprises: a broad-spectrum light source, the flux from which is emitted through an aperture; an optical system which collimates the primary source; a system which disperses the beam chromatically; an optical system which forms an image of the dispersed primary source at a given position, at which a spatial mask is placed in order to filter the received irradiance spectrally; an optical system which captures the filtered spectrum and returns, mixes and concentrates same in a secondary source with the desired spectral, angular, and spatial characteristics; an optical system which collimates the secondary source such that it reproduces the angular characteristics of the sun; and a control system.

Abstract: In a light sensor test unit, a test circuit is built in a display panel and connected to an output node of a light sensor which senses an intensity of an external light. When external light having a predetermined intensity is provided to the light sensor, the test circuit outputs a driving signal in response to a sensing signal output from the output node. A test pixel part includes pixels selected from a plurality of pixels arranged in the display panel and receives the driving signal from the test circuit to display a gray-scale corresponding to the driving signal. A brightness measurer measures a brightness corresponding to the gray-scale displayed in the test pixel part to compare the measured brightness with a predetermined brightness, thereby testing whether the light sensor built in the display panel is normally operated.

Abstract: A system and method for characterizing the solar cell conversion performance and detecting a defect in a solar cell includes applying an optical test signal to the solar cell using the multiple-scanning method, measuring the solar cell photocurrent in response to the solar cell illumination by the multiple-scanning method, and detecting a defect and finding its location based on the characteristic mapping of solar cell photocurrent, which is obtained by the multiple-scanning method through the divisional control of light transmittance by the LVP (light valve panel). The defect may be a solar cell subsection which has abnormally low photocurrent below a critical value and can be caused by a short between the emitter and the base of solar cell. The LVP may be realized in any one of a variety of ways. For example, the LVP may be a flat-panel display such as AMLCD (Active-Matrix Liquid Crystal Display) and AMOLED (Active-Matrix Organic Light Emitting Diode).
