In hybrid photovoltaics, an organic and an inorganic semiconductor are combined in the active layer, with the advantages of both material classes in a single device. The organic component contributes towards the possibility for wet chemical device preparation with potentially low costs in combination with achieving flexible devices. From the inorganic component an increase in stability, as well as superior opto‐electronic properties, is added. Given the large diversity of organic and inorganic semiconductors, a large number of possible realizations of hybrid solar cells emerge. In the present review, we limit to hybrid solar cells which combine conjugated polymers with inorganic materials such as titanium dioxide, zinc oxide, silicon, germanium and quantum dots to keep focused. Particular emphasis is put on different routes to tailor nanostructures, such as the use of semiconductor block copolymers. The inorganic component is either synthesized directly in one of the blocks or added as a pre‐synthesized nanomaterial to form the hybrid material. Alternatively, the block copolymer is used as a structure‐directing template in a sol–gel synthesis approach to have tailored inorganic nanostructures, which are back‐filled with the organic component to fabricate the hybrid material. Hybrid solar cells based on crystalline Si are discussed for comparison.

A Low Temperature Route toward Hierarchically Structured Titania Films for Thin Hybrid Solar Cells

The requirement of high‐temperature calcination for titanium dioxide in (solid‐state) dye‐sensitized solar cells (DSSCs) implies challenges with respect to reduced energy consumption and the potential for flexible photovoltaic devices. Moreover, the use of dye molecules increases production costs and leads to problems related with dye bleaching. Therefore, fabrication of dye‐free hybrid solar cells at low temperature is a promising alternative for current DSSC technology. In this work the authors fabricate hierarchically structured titania thin films by combining a polystyrene‐block‐polyethylene oxide template assisted sol–gel synthesis with nano‐imprint lithography at low temperatures. The achieved films are filled with poly(3‐hexylthiophene) to form the active layer of hybrid solar cells. The surface morphology is probed via scanning electron microscopy and atomic force microscopy, and the bulk film morphology is examined with grazing incidence X‐ray scattering. Good light absorption by the active layer is proven by UV–vis spectroscopy. An enhancement in light absorption is observed and ascribed to light scattering in mesoporous titania films with imprinted superstructures. Accordingly a better photovoltaic performance is found for nano‐imprinted solar cells at various angles of light incidence.

Given the broad use of nanostructured crystalline titania films, an environmentally friendly and more sustainable synthesis route is highly desirable. Here, a water-based, low-temperature route is presented to synthesize nanostructured foam-like crystalline titania films. A pearl necklace-like nanostructure is introduced as tailored titania morphology via biotemplating with the use of the major bovine whey protein ß-lactoglobulin (ß-lg). It is shown that titania crystallization in a brookite-anatase mixed phase is promoted via spray deposition at a comparatively low temperature of 120 °C. The obtained crystallites have an average grain size of (4.2 ± 0.3) nm. In situ grazing incidence small-angle and wide-angle X-ray scattering (GISAXS/GIWAXS) are simultaneously performed to understand the kinetics of film formation and the templating role of ß-lg during spray coating. In the ß-lg:titania biohybrid composites, the crystal growth in semicrystalline titania clusters is sterically directed by the condensing ß-lg biomatrix. Due to using spray coating, the green chemistry approach to titania-based functional films can be scaled up on a large scale, which can potentially be used in photocatalytic processes or systems related to energy application.
