In this paper the concept of new selectively transparent polymer layer, dedicated for improvement of innovative solar cell structure efficiency is presented. Various polymer materials differing in optical, mechanical and thermal properties are being considered. The texturisation of the front surface is proposed in order to assure difference in the transmission of radiation coming from both sides towards higher solar conversion efficiency. The theoretical approach is verified by the measurements. The fabrication process of different texturisation patterns on polymer foil using novel laser ablation method is described and the preliminary results are presented.
