Incorporation of Counter Ions in Organic Molecules: New Strategy in Developing Dopant-Free Hole Transport Materials for Efficient Mixed-Ion Perovskite Solar Cells

Nikolaos Vlachopoulos, Ulf Anders Hagfeldt, Lin Yang, Jiahuan Zhang, Monica Marcela Lira Cantu, Liang Wang

Hole transport matertial (HTM) as charge selective layer in perovskite solar cells (PSCs) plays an important role in achieving high power conversion efficiency (PCE). It is known that the dopants and additives are necessary in the HTM in order to improve t ...

The synergistic effect of H2O and DMF towards stable and 20% efficiency inverted perovskite solar cells

Mohammad Khaja Nazeeruddin

A high quality thick (500 nm) CH3NH3PbI3 perovskite absorber with a horizontal grain size up to 3 μm and a lateral size equal to the film thickness was prepd. by the synergistic effect of a H2O additive and DMF vapor treatment via a two-step spin coating ...

Ternary semitransparent organic solar cells with a laminated top electrode

Frank Nüesch, Roland Hany, Jakob Heier, Lei Wang, Surendra Babu Anantharaman, Paolo Testa

Tinted and colour-neutral semitransparent organic photovoltaic elements are of interest for building-integrated applications in windows, on glass roofs or on facades. We demonstrate a semitransparent organic photovoltaic cell with a dry-laminated top elect ...

Enhancing the power conversion efficiency of dye-sensitized solar cells via molecular plasmon-like excitations

Antonio Prlj, Ganna Gryn'ova, Jian-Hao Li

A tactic for employing molecular plasmons to enhance solar-to-electric power conversion efficiency of dye-sensitized solar cells is introduced. We offer general design principles of dimeric dyes in which a strong plasmonic interaction between two π-conjuga ...
