Solar Cell Gamma Radiation Detector

Normally the signal caused by x rays or gamma rays in the solar cell output is miniscule compared to the signal that is created by visible light.

Solar cell gamma radiation detector.

Oct 11 2011 3 logannc. A number of pin photodiodes phototransistors and solar panels have been exposed to gamma irradiation. Thermoluminescence detectors tld main dosimetry peak was investigated. So the method of measurement is as vastly different.

They were discovered by victor hess in 1912 in balloon experiments. Lead free perovskites with lead replaced by tin. This paper presents the behavior of various optoelectronic devices after gamma irradiation. These are first and foremost light emitting diodes and lasers operating in the near ir and visible regions optical filters solar cells x ray and gamma radiation detectors and high sensitivity electrooptical sensors for coherent detection at frequencies above 30 thz 1.

The characteristics of a 25 4 x 91 cm solar cell panel used as an x ray and gamma ray radiation monitor are presented. However as an indirect band semiconductor silicon has relatively low. Although both a solar cell and photo diode are essentially a pn junction there construction and the way they are used is vastly different almost opposite. Cosmic rays are high energy protons and atomic nuclei which move through space at nearly the speed of light they originate from the sun from outside of the solar system and from distant galaxies.

The dragonscale detector uses basic solar cell physics to create a signal just from the x rays and gamma rays. Gamma and x ray czt room temperature radiation detectors. Direct measurement of cosmic rays especially at lower energies has become possible since the launch of the first satellites in. Solar cells are known to react to x rays and or gamma rays impinging on them.

There is much difference between a gamma ray and optical light as there is to radio waves. And other novel approaches. However i would think that if it were possible to absorb a significant amount given a thick enough cell then the energy absorbed might. Our group is also investigating tandem solar cells with perovskite and silicon solar cells.

I v characteristics current dependance on voltage of these devices have been measured before and after irradiation. Several types of photodiodes and phototransistors were used in the experiment. One of the problems is that while visible light will easily be asborbed in a thin layer on a solar cell gamma radiation will easily penetrate large layers of shielding. Applications for monitoring the primary x ray beam are described at different values of operating currents and voltages as well as for directional dependence of scattered radiation.
