Block copolymer morphologies in dye-sensitized solar cells: probing the photovoltaic structure-function relation. by Crossland, E, Nedelcu, M, Ducati, C, Ludwigs, S, Hillmyer, M, Steiner, U, Snaith, H

“…We integrate mesostructured titania arrays into dye-sensitized solar cells by replicating ordered, oriented one-dimensional (1D) columnar and three-dimensional (3D) bicontinuous gyroid block copolymer phases. The solar cell performance, charge transport, and recombination are investigated. …”

Improved conductivity in dye-sensitised solar cells through block-copolymer confined TiO2 crystallisation by Guldin, S, Huettner, S, Tiwana, P, Orilall, M, Uelguet, B, Stefik, M, Docampo, P, Kolle, M, Divitini, G, Ducati, C, Redfern, S, Snaith, H, Wiesner, U, Eder, D, Steiner, U

“…In contrast to earlier methods, the high temperature stability of mesoporous titania is enabled by the self-assembly of the amphiphilic block copolymer polyisoprene-block-polyethylene oxide (PI-b -PEO) which compartmentalises TiO2 crystallisation, preventing the collapse of porosity at temperatures up to 700 °C. …”

Layer-by-layer formation of block-copolymer-derived TiO(2) for solid-state dye-sensitized solar cells. by Guldin, S, Docampo, P, Stefik, M, Kamita, G, Wiesner, U, Snaith, H, Steiner, U

“…Here, a study on the temporal evolution of block-copolymer-directed mesoporous TiO(2) films during annealing and calcination is presented. …”

Control of Solid-State Dye-Sensitized Solar Cell Performance by Block-Copolymer-Directed TiO2 Synthesis by Docampo, P, Guldin, S, Stefik, M, Tiwana, P, Orilall, M, Huettner, S, Sai, H, Wiesner, U, Steiner, U, Snaith, H

Self-assembly as a design tool for the integration of photonic structures into excitonic solar cells by Guldin, S, Docampo, P, Hüttner, S, Kohn, P, Stefik, M, Snaith, H, Wiesner, U, Steiner, U

“…An alternative route is based on the fact that the refractive index of the mesoporous layer can be finely tuned by the interplay between block copolymer self-assembly and hydrolytic TiO 2 sol-gel chemistry. …”

A bicontinuous double gyroid hybrid solar cell. by Crossland, E, Kamperman, M, Nedelcu, M, Ducati, C, Wiesner, U, Smilgies, D, Toombes, G, Hillmyer, M, Ludwigs, S, Steiner, U, Snaith, H

“…The freestanding gyroid network is fabricated by electrochemical deposition into the 10 nm wide voided channels of a self-assembled, selectively degradable block copolymer film. The highly ordered pore structure is ideal for uniform infiltration of an organic hole transporting material, and solid-state dye-sensitized solar cells only 400 nm thick exhibit up to 1.7% power conversion efficiency. …”

Charge Transport Limitations in Self-Assembled TiO2 Photoanodes for Dye-Sensitized Solar Cells by Docampo, P, Guldin, S, Steiner, U, Snaith, H

“…Despite continuous progress, limitations in charge diffusion through the mesoporous photoanode still constrain the device thickness and hence result in reduced light absorption with the most common sensitizers. Here we examine block copolymer-assembled photoanodes with similar surface area and morphology but a large variation in crystal size. …”
