Three-dimensional photovoltaics

Three-dimensional nanopillar-array photovoltaics on low-cost and flexible substrates.

Solar energy represents one of the most abundant and yet least harvested sources of renewable energy. In recent years, tremendous progress has been made in developing photovoltaics that can be potentially mass deployed. Of particular interest to cost-effective solar cells is to use novel device structures and materials processing for enabling acceptable efficiencies. In this regard, here, we re...

DNA brick crystals with prescribed depths.

The ability to assemble functional materials with precise spatial arrangements is important for applications ranging from protein crystallography to photovoltaics. Here, we describe a general framework for constructing two-dimensional crystals with prescribed depths and sophisticated three-dimensional features. The crystals are self-assembled from single-stranded DNA components called DNA brick...

Organic photovoltaics: technology and market

Organic photovoltaics has come into the international research focus during the past three years. Up to now main efforts have focused on the improvement of the solar conversion efficiency, and in recent efforts 5% white light efficiencies on the device level have been realized. Despite this in comparison to inorganic technologies low efficiency, organic photovoltaics is evaluated as one of the ...
