Solar Cell Gamma Radiation Detector

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.

Solar cell gamma radiation detector.

They were discovered by victor hess in 1912 in balloon experiments. And other novel approaches. There is much difference between a gamma ray and optical light as there is to radio waves. Oct 11 2011 3 logannc.

Direct measurement of cosmic rays especially at lower energies has become possible since the launch of the first satellites in. So the method of measurement is as vastly different. 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. Monocrystalline silicon solar cell of the construction n pp passivated emitter solar cell pesc irradiated by 60 co gamma ray dose was studied.

Our group is also investigating tandem solar cells with perovskite and silicon solar cells. Gamma and x ray czt room temperature radiation detectors. Thermoluminescence detectors tld main dosimetry peak was investigated. Silicon solar cells of n pp or n pp structures are widely used as solar radiation detector 6 and gamma dosimeter 7 8.

The dragonscale detector uses basic solar cell physics to create a signal just from the x rays and gamma rays. Lead free perovskites with lead replaced by tin. A number of pin photodiodes phototransistors and solar panels have been exposed to gamma irradiation. 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.

Several types of photodiodes and phototransistors were used in the experiment. The results showed that it is possible to determine gamma dose more accurate from tl main dosimetry peak for monocrystalline silicon solar cell in comparison with tld 100. This paper presents the behavior of various optoelectronic devices after gamma irradiation. However i would think that if it were possible to absorb a significant amount given a thick enough cell then the energy absorbed might.

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. I v characteristics current dependance on voltage of these devices have been measured before and after irradiation. The characteristics of a 25 4 x 91 cm solar cell panel used as an x ray and gamma ray radiation monitor are presented. Solar cells are known to react to x rays and or gamma rays impinging on them.
