PHOTOELECTRIC CONVERSION ELEMENT, PHOTODETECTOR, PHOTODETECTION SYSTEM, ELECTRONIC APPARATUS, AND MOBILE BODY - A simplified explanation of the abstract

This abstract first appeared for US patent application 18267712 titled 'PHOTOELECTRIC CONVERSION ELEMENT, PHOTODETECTOR, PHOTODETECTION SYSTEM, ELECTRONIC APPARATUS, AND MOBILE BODY

Simplified Explanation

The patent application describes a highly functional photoelectric conversion element with multiple photoelectric converters and an optical filter.

• Semiconductor substrate
• First photoelectric converter detects light in a first wavelength range and converts it
• Second photoelectric converter detects light in a second wavelength range and converts it
• Optical filter allows light in the second wavelength range to pass more easily than light in the first wavelength range
• First light-shielding member surrounds the optical filter and shields light in the second wavelength range

Potential Applications

• Solar panels
• Photodetectors
• Image sensors

Problems Solved

• Efficiently detecting and converting light in different wavelength ranges
• Minimizing interference between different types of light

Benefits

• Improved sensitivity to different types of light
• Enhanced performance in various applications
• Potential for increased energy efficiency

Original Abstract Submitted

A highly functional photoelectric conversion element is provided. The photoelectric conversion element includes: a semiconductor substrate; a first photoelectric converter that is provided on the semiconductor substrate, and detects light in a first wavelength range and photoelectrically converts the light; a second photoelectric converter that is provided at a position overlapping the first photoelectric converter in a thickness direction of the semiconductor substrate in the semiconductor substrate, and detects light in a second wavelength range and photoelectrically converts the light; an optical filter that is sandwiched between the first photoelectric converter and the second photoelectric converter in the thickness direction, and through which the light in the second wavelength range passes more easily than the light in the first wavelength range; and a first light-shielding member that surrounds the optical filter along a plane orthogonal to the thickness direction to at least partially overlap the optical filter in a plane direction along the plane, and shields at least the light in the second wavelength range.
