| Abstract | ||||
| A film of DBM is deposited on a -Si single crystal to fabricate a p-DBM/n-Si (thickness ≈ 90 nm). Researchers have explored the electrical and photoelectrical characteristics of photovoltaic cells by analyzing current. have been studied through current analysis. Photovoltaic cell. Electrical and photoelectrical properties have "The matter has been under investigation." by the current density – voltage measurements at different temperatures ((J-V) characteristics)."The fabricated cell displayed rectifying properties, with a rectification ratio." R=4043 at 1 Volt. The obtained value of the series resistance Rs and the shunt resistance Rsh at room temperature were determined to be 750 Ω and 1700 Ω, respectively. At low voltages (V<1V), the dark forward current density is controlled by the tunneling mechanism, while at relatively high voltage (V>1V), a space charge-limited-conduction mechanism is observed, controlled by a single trap level. The C-V measurements indicate an abrupt junction with a built-in voltage of 0.78V. Finally, the cell exhibited photovoltaic characteristics with an open-circuit voltage of 780 mV, a short-circuit current of 1.2x10-6 mA, and a power conversion efficiency of 1.48%. These parameters were estimated at room temperature under light illumination from a source with an input power density of 20 mWatt/cm2. These parameters were estimated at room temperature under light illumination from a source with an input power density of 20 mWatt/cm2. | ||||
