A solid-state imaging element (1) according to the present disclosure includes a pixel array unit (10) in which a plurality of light receiving pixels (11) is two-dimensionally arranged. Each of the light receiving pixels (11) includes an organic photoelectric conversion unit (61) and another photoelectric conversion unit. The organic photoelectric conversion unit (61) includes a photoelectric conversion layer (63) made of an organic semiconductor material, a first electrode (62) located on a light incident side of the photoelectric conversion layer (63), and a second electrode (65) located on a side opposite to the light incident side of the photoelectric conversion layer (63). The other photoelectric conversion unit is located on a side opposite to the light incident side of the organic photoelectric conversion unit (61), and performs photoelectric conversion in a wavelength region different from a wavelength region of the organic photoelectric conversion unit (61). The second electrode (65) is connected to a connection wiring (51) including a metal wiring (54) made of metal and a transparent wiring (53) made of a transparent conductive film. The metal wiring (54) extends in a horizontal direction from a peripheral portion of the light receiving pixel (11) to a peripheral portion of the pixel array unit (10).

According to an aspect, a detection device includes: an optical sensor; a first light source and a second light source that are configured to emit light to the optical sensor; and a detection circuit that is coupled to the optical sensor and is configured to output a sensor value corresponding to a photocurrent output from the optical sensor in each of a plurality of readout periods provided in a time-division manner. The first light source and the second light source are configured to be alternately lit for each of the readout periods, and to be lit a plurality of times in a pulsed manner in each of the readout periods. The detection circuit is configured to measure an integrated value or an average value of the photocurrent output in response to the light lit in a pulsed manner in each of the readout periods.

Solar cell modules and methods of fabrication are described. In an embodiment, a pair of tandem solar cells are a step surface or trench within the top subcell of a tandem solar cell is at least partially filled with another material such as an insulator support or electrically conductive support to transfer stress away from the absorber layer of the top subcell of the tandem solar cells when stacked or connected with ribbon.

A self-powered display device is proposed, and includes a substrate, a first photoelectric conversion unit, a light-transmitting display module and a wireless charging module. The first photoelectric conversion unit is disposed on the substrate and located in a display region. The light-transmitting display module is stacked on the first photoelectric conversion unit. A first light penetrates the light-transmitting display module, and the first photoelectric conversion unit converts the first light into a first electrical energy and provides the first electrical energy to the light-transmitting display module. The wireless charging module is disposed on the substrate and located in a non-display region. The wireless charging module receives a second light and converts the second light into a second electrical energy, and provides the second electrical energy to the light-transmitting display module. A wavelength range of the first light is different from a wavelength range of the second light.
