| Abstract | ||
| We present an experimental evidence of the effect of the femtosecond laser pulses on the spectral response of the Silicon photovoltaic cell. The response of this device is covering the visible to near infrared spectral region. The responsivity of the photovoltaic solar cell is enhanced from 0.18A/W to 0.25A/W and/or the conversion efficiency increase from about 9% to about 14% due to irradiation effect. All treatments and measurements are made at room temperature. Results show that the responsivity is enhanced and the nano-structured groves of the 700-900 nm range are observed. | ||
