Photoconductive Detectors – intrinsic, extrinsic, design, thermal

Photoconductive detectors are a type of photodetectors which are based on photoconductive semiconductor materials. Here, the absorption of incident light creates non-equilibrium electrical carriers, and that reduces the electrical resistance across two electrodes. There are also some exotic cases with negative photo conductivity, i.e., with an increase of resistance caused by

6 FAQs about [Photocell Silicon Photovoltaic Detector]

What are the characteristics of a photovoltaic detector?

According to the research results,the detector has 4.15 × 10 2 excellent rectification characteristics and 1.93 × 10 3 high switch ratio, and the photovoltaic effect is significant.

How does a photovoltaic detector work?

The photocurrent rises and falls as the light turned on and off at the 0 V bias voltage, indicating that the device is indeed a working photovoltaic detector, realizing self-driven DUV detection. Besides, the device also displays good stability in cycle test.

Why are silicon photodetectors used for UV detection?

The silicon photodetectors used for UV detection can face limitations caused by their material properties, i.e., in high-temperature operation, they must frequently be cooled to reduce leakage current and the detection system’s noise. What is more, an optical filter is often applied in order to block visible and infrared radiation.

What are the rectification properties of a photovoltaic detector?

According to the research results, the detector has excellent rectification properties of 4.15 × 10 2 and a high switching ratio of 1.93 × 10 3, with a significant photovoltaic effect produced.

Are photodetectors made of 2D materials used in the ultraviolet range?

As mentioned previously, concepts of photodetectors made of 2D materials are also used in the ultraviolet range. An example of such a detector is the hybrid detector shown in Figure 59 —its idea is described in Table 1 as a photo-FET.

How do you calculate D* in a silicon photodetector?

For the MoS 2 /planar silicon photodetector, D*is calculated using the same method to be 9.93 × 10 10 cm Hz 1/2 W −1. The increase in D* is attributed to the efficient light absorption by SiNPAs, which increases the photocurrent.
