光电转换装置和成像系统
摘要：
本发明涉及光电转换装置和成像系统。根据示例性实施例的光电转换装置包括包含光电转换单元、复位晶体管和输出来自光电转换单元的信号的放大器晶体管的像素。光电转换单元包含第一电极、第二电极、光电转换层和设置在光电转换层与第二电极之间的绝缘层。光电转换单元根据第一电极与第二电极之间的电压交替执行蓄积操作和排出操作。在多个排出操作之中的两个连续的排出操作之间的时段中，多次执行复位晶体管复位第二电极上的电压的复位操作。
摘要（英）：

A photoelectric conversion device according to an exemplary embodiment includes a pixel (100) which includes a photoelectric conversion unit (101), a reset transistor (102), and an amplifier transistor (104) that outputs a signal from the photoelectric conversion unit (101). The photoelectric conversion unit (101) includes a first electrode (201), a second electrode (209), a photoelectric conversion layer (205), and an insulating layer (207) disposed between the photoelectric conversion layer (205) and the second electrode (209). The photoelectric conversion unit (101) alternately performs an accumulation operation and a discharge operation in accordance with the voltage between the first electrode (201) and the second electrode (209). In a period between two consecutive discharge operations among a plurality of discharge operations, a reset operation in which the reset transistor (102) resets the voltage on the second electrode (209) is performed a plurality of times.
