Abstract
The photo-reflectance and laser-ablation properties of a part of an organic solar cell, a perylene derivative and the phthalocyanine (denoted as PV/H2 Pc) were investigated. The reflectance of a PV/H2Pc bilayer was higher than the single layer samples of H2Pc and PV. Considering the photovoltaic effe ct in the corresponding solar cell and chemically doped perylene, the prese nt reflection was characterized to be the photo-generated carrier in the PV layer. The present property can be classified into organic reflectance-tun able material, and is useful as a coating material to realize uniform laser ablation. A remarkable difference was observed in laser ablation of polyst yrene film, in comparison with that of the PV/H2Pc bilayer, when 1060 nm la ser incident took place on the coating material. Without the coating the la ser pulse formed a spiky structure as a trace of self-focusing, while for t he coated film the ablation trace was from the upstream on the axis without a spiky structure. These phenomena are advantageous for the targets of dir ect-driven inertial fusion energy.
