Energy level alignment and electron recombination rate chaining has been occurred in dye-sensitized photoanode interface with solid polymer electrolyte (SPE), comparison with common liquid electrolyte (LE). Herein, the physic-chemical origin of these phenomena is firstly investigated by a comparison study between dye-sensitized solar cells (DSCs) with SPE and LE which has been quantitatively conducted by changing the cation, lithium (Li+) and 1-methyl-3-propylimidazolium (MPI+), in the electrolyte. The main reasons to above changing may be due to the ethylene oxide (EO) units of SPE containing PEO and/or poly(ethylene glycol) dimethyl ether (PEGDME). The EO units coordinatively interact with Ti atoms of the TiO2 layer to form a passivation layer, resulting in the reduction in the electron recombination and the upward shift in the CB. The EO units also interact with both Li+ and MPI+, but much stronger with the former than the latter, which captures cations, particularly Li+, and reduces in turn the effective salt concentration in the electrolytes. Cationic capturing consequently decreased the adsorbed concentration of Li+ on the TiO2 layer, and the less decrease in Ec as measured quantitatively for the first time, and finally the increase in Voc. In conclusion, the above proven advantageous characters of SPE, less downward-shifting in the TiO2 CB and prohibiting the electron recombination, can be expected to be utilized for higher performance in SPE-based sensitized solar cells.

International Conference on Hybrid and Organic Photovoltaics
International Conference on Hybrid and Organic Photovoltaics (HOPV) is celebrated yearly in May. The main topics are the development, function and modeling of materials and devices for hybrid and organic solar cells. The field is now dominated by perovskite solar cells but also other hybrid technologies, as organic solar cells, quantum dot solar cells, and dye-sensitized solar cells and their integration into devices for photoelectrochemical solar fuel production.
Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics
The main topics of the Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP) are discussed every year in Asia-Pacific for gathering the recent advances in the fields of material preparation, modeling and fabrication of perovskite and hybrid and organic materials. Photovoltaic devices are analyzed from fundamental physics and materials properties to a broad set of applications. The conference also covers the developments of perovskite optoelectronics, including light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
The International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics (NIPHO) is the best place to hear the latest developments in perovskite solar cells as well as on recent advances in the fields of perovskite light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
