Special Issue Information

Dear Colleagues,

Recent discoveries have revealed a breakthrough in organometal perovskites photovoltaics. While the biggest advances in performance thus far have arisen from the optimization of perovskite materials, additives, and deposition techniques, understanding the role of interfaces in the device is crucial to maximizing the performance of the system. The outstanding optoelectronic performance is truly attractive; however, stability issues are also the crucial for the success of commercial applications. 

This Special Issue will provide a forum to disseminate new developments of perovskite solar cells such as new composition perovskite materials or fabrication processes of perovskite layers, electron transport layers, and organic/inorganic hole transport layers. The properties and their treatment in perovskite solar cell interfaces such as protective layers, grain/interface passivation, and stability issues also welcome.

Perovskite solar cells (PSCs) have achieved tremendous success within just a decade. This success is critically dependent upon compositional engineering, morphology control of perovskite layer, or contingent upon high-temperature annealed mesoporous TiO2, but quantitative analysis of the role of facile TiCl4 treatment and thickness control of the compact TiO2 layer has not been satisfactorily undertaken. Herein, we report the facile thickness control and post-treatment of the electron transport TiO2 layer to produce highly efficient planar PSCs. TiCl4 treatment of TiO2 layer could remove the surface trap and decrease the charge recombination in the prepared solar cells. Introduction of ethanol into the TiCl4 aqueous solution led to further improved open-circuit voltage and short-circuit current density of the related devices, thus giving rise to enhanced power conversion efficiency (PCE). After the optimal TiCl4 treatment, PCE of 16.42% was achieved for PSCs with TiCl4 aqueous solution-treated TiO2 and 19.24% for PSCs with TiCl4 aqueous/ethanol solution-treated TiO2, respectively. This work sheds light on the promising potential of simple planar PSCs without complicated compositional engineering and avoiding the deposition and optimization of the mesoporous scaffold layer.
