Deskripsi
In this research 300 fs pulses of Yb:KGW laser has been applied to form electron transport layer TiO2 of Grӓtzel type organic solar cells (OSC) with different surface roughness. Profiler, AFM, SEM has been used to define surfaces. Scattering of 532 nm wavelength light from ablated regions has been measured. OSC have been formed onto TiO2 and I-V characteristics have been measured. Investigation results demonstrated that laser treatment of TiO2 has impact to the I-V dependencies of OSC.
