“…The E g value was determined by extrapolating the linear part of the plot (αhν) 2 vs. (hν) in the abscissa (axis x), which indicates a direct optical transition. The (αhν) 2 vs. (hν) plots are shown in Fig.…”

“…Indium sulfide has been recognized as an alternative material due to their stability, transparency, photoconductive nature and because of the energy band gap that can be varied between 2 and 2.75 eV depending on its composition [1][2][3][4][5][6]. Several crystalline phases have been reported for the In 2 S 3 thin films (α, β and γ) and it has been found that the most stable phase at room temperature is the β-tetragonal [6].…”

Indium sulfide (In 2 S 3 ) thin films have been synthesized by chemical bath deposition technique onto glass substrates using In(NO 3 ) 3 as indium precursor and thioacetamide as sulfur source. X-ray diffraction studies have shown that the crystalline state of the as-prepared and the annealed films is β-In 2 S 3 . Optical band gap values between 2.27 and 2.41 eV were obtained for these films. The In 2 S 3 thin films are photosensitive with an electrical conductivity value in the range of 10, depending on the film preparation conditions. We have demonstrated that the In 2 S 3 thin films obtained in this work are suitable candidates to be used as window layer in thin film solar cells. These films were integrated in SnO 2 :F/In 2 S 3 /Sb 2 S 3 /PbS/C-Ag solar cell structures, which showed an open circuit voltage of 630 mV and a short circuit current density of 0.6 mA/cm 2 .

“…The estimation of the open circuit voltage from the results of the PEC measurements is possible. PEC measurement shows the semiconductor conduction-type and photosensitivity [2][3][4][5][6][7][8][9][10][11].…”

“…When a light with certain intensity strikes the semiconductor, a number of the minority carrier is excited to the conduction band and the same number of majority carriers is left behind them in the valence band. However, the photocurrent of a semiconductor is different [2][3][4][5][6][7][8][9][10][11] under anodic and cathodic biases for a certain intensity of light. The important matter is that the PEC measurements of some semiconductors show photocurrent at zero bias potential [2,[5][6][7]11].…”

Open circuit voltage is an essential factor to judge the performance of the photovoltaic cells. Basically, the photo-electrochemical (PEC) measurement shows the solid/electrolyte chemical interaction under light illumination. The PEC measurement reflects the electrical and optical properties of the semiconductors. The optical sensitivity of a semiconductor is used to derive an equation. In the present study, we introduced an equation to estimate the open circuit voltage of a pn junction from the PEC measurements of the individual layers.

“…In our previous reports, we have deposited InS x O y electrochemically onto indium-doped tin oxide (ITO)-coated glass substrates from an aqueous bath containing 0.01 mol/L of In 2 (SO 4 ) 3 and 0.1 mol/L of Na 2 S 2 O 3 using a two-step-pulse biasing [11]. Due to the instability of ITO in the acidic bath at the cathodic biasing [12], the fluorine-doped tin oxide (FTO)-coated glass was used as a substrate in a separate report [13].…”
