Performance Analysis of γ-Radiation Test Monitor Using Monocrystalline n+pp++ Silicon Solar Cell: CsI(Tl) Scintillator

Table 1

Dimensions and physical properties of (a) solar cell and (b) CsI(Tl) scintillator [9] employed.

(a) Solar cell n+pp++

Cell type	Solar cell area (cm^2)	Sensitive area with CsI(TI) (cm^2)	Peak sensitivity wavelength (μm)	Thickness (μm)	Short circuit current (A)	Open circuit voltage (V)	Conversion efficiency %	Output power (W)
Single crystal silicon	10 × 10	5 × 5	0.5 to 0.53	400	3.2	0.6	16	1.2–1.4

Note: the electrical parameters for monocrystalline solar cells n+pp++ PESC of dimensions (10 cm × 10 cm) are related to the conditions of solar irradiation 1000 W/m², air mass (AM) 1.5 spectrum, and cell temperature 25°C.

(b) CsI(Tl) scintillator

Light output (%)	Max. emission wavelength (μm)	Decay time (nS)	H. thickness (cm)	Density (gm/cm^3)	Melting point (°C)	Dimensions (mm^3)
45–50	550	10^3	2.0	4.51	894	50 × 50 × 10

Note: light output: light output % of NaI(Tl); H. thickness: half-thickness value for Cs(662 keV).
