Backside layer of thin-film photovoltaic cells
The Deterministic Quasi-Periodic Structure (DQPS) is composed of an active absorption layer, a self-assembled quasi-periodic grating, and a distributed Bragg reflector (DBR). The active layer can be p-n, p-i-n or multi-junction made of semiconductors, converting sunlight into electrical energy. The grating, fabricated by self-assemble methods such as aluminum anodization or block copolymerization, is used to diffract the light into oblique angles. It is comprised of two materials with different refractive indices which form one-dimensional or two-dimensional arrays.
