Professor Wang and colleagues have devised of a practical low cost large-scale production method for multilayered photovoltaic device fabrication. Hybrid solar cells based on nanocrystals and nanoparticles require high temperature and are expensive to produce. In this technology UCLA researchers developed a copolymer template to form the nanoparticle array which offers versatility in construction and low cost compared to conventional thermal annealing and chemical synthesis methods. The approach obviates the need for high temperature which offers advantages for mass production. The technology has wide applications for portable devices displays modulators detectors LEDs and power stations.
