Mater. Chem. A, 2013, 1, Pp. 10142–10147. Abstract

We prepared a quasi-solid electrolyte for dye-sensitized solar cells (DSSCs) that consist of ionic liquid and modified silica particles. Commercial bare silica F5 particles and modified silica F5 by NH2 and NH3+ groups were prepared, and fully characterized. The best photovoltaic performance was observed using the NH2 modified silica particles giving an open circuit voltage (Voc) of 815 mV, a short-circuit current (Jsc) of 11.23 mA cm-2, and a fill factor (FF) of 0.75 corresponding to an overall power conversion efficiency of 7.04% at 100 mW cm-2 AM 1.5. The modification of the silica particles by NH2 groups increases the Voc of DSSCs by around 60 mV compared to pure ionic liquid electrolyte based DSSCs.

Etgar Lioz. 2/2013. “Semiconductor Nanocrystals as Light Harvesters in Solar Cells.” Materials, 2013, 6, Pp. 445-459. Abstract

Photovoltaic cells use semiconductors to convert sunlight into electrical current
and are regarded as a key technology for a sustainable energy supply. Quantum dot-based
solar cells have shown great potential as next generation, high performance, low-cost
photovoltaics due to the outstanding optoelectronic properties of quantum dots and their
multiple exciton generation (MEG) capability. This review focuses on QDs as light
harvesters in solar cells, including different structures of QD-based solar cells, such as QD
heterojunction solar cells, QD-Schottky solar cells, QD-sensitized solar cells and the recent
development in organic-inorganic perovskite heterojunction solar cells. Mechanisms,
procedures, advantages, disadvantages and the latest results obtained in the field are
described. To summarize, a future perspective is offered.
