International audienceAnatase TiO2 nanoparticles were prepared by a simple sol-gel method at moderate temperature. X-ray powder diffraction (XRD) and Raman spectroscopy revealed the exclusive presence of anatase TiO2 without impurities such as rutile or brookite TiO2. Thermogravimetric analysis confirmed the formation of TiO2 at about 400 °C. Particle size of about 20 nm observed by transmission electron microscopy matches well with the dimension of crystallites calculated from XRD. The electrochemical tests of the sol-gel-prepared anatase TiO2 show promising results as electrode for lithium-ion batteries with a stable specific capacity of 174 mAh g−1 after 30 cycles at C/10 rate. The results show that improvement of the electrochemical properties of TiO2 to reach the performance required for use as an electrode for lithium-ion batteries requires not only nanosized porous particles but also a morphology that prevents the self-aggregation of the particles during cycling

“…As discussed in previous section, TiO2 NPs as the interface modification layer can dramatically improve the stability of OSCs [29,30]. Thus, the TiO2 NPs were also introduced into the interface between the PCBM layer and the Al electrode for hopefully enhancing the stability of PHJPSCs.…”

“…Thus, TiO2 nanoparticles (NPs) was developed to be a proper candidate to replace TiOx because of its thermally stability and the role as efficient ETL or HBL [54,55]. In order to overcome conventional complex procedures and the drawbacks of a high-temperature hydrolytic process and universal low carrier mobility, we developed newly solution-based method to synthesize high-quality TiO2 NPs [29]. Based on the solvent types, three kinds of TiO2 NPs, i.e., O3-TiO2, O7-TiO2 and H7-TiO2, can be synthesized, respectively (Fig.…”

“…These three kinds of TiO2 NPs were used to fabricate polymer solar cells based on the bulk heterojunction of P3HT:PCBM with a structure of ITO/PEDOT:PSS/ P3HT:PCBM/TiO2/Al, and the performance parameters are summarized in Table 1 [29]. As compared with the reference device without TiO2 NPs layer, polymer solar cells with O3-TiO2 NPs showed the similar performance parameters, while the performance parameters of O7-TiO2 and H7-TiO2 NPs-based polymer solar cells showed great improvement.…”

Organic solar cells (OSCs) continuously attract much attention due to their potentials as the low-cost and lightweight sources of renewable energy, and the power conversion efficiency (PCE) of the state-of-the-art OSCs has reached over 10.0%. Especially, there has been an unexpected breakthrough and rapid evolution of highly efficient organic-inorganic hybrid perovskite solar cells (PSCs), and the PCE has been improved to over 20%. The interface plays a very important role on the performance of both OSCs and PSCs, as well as their stability. It is imperative to control the interface properties and understand the mechanisms for obtaining highly efficient OSCs and PSCs. In this review, we will summarize our research progress on the interface modification of OSCs and PSCs using the electron transport layer and hole transport layer, as well as the molecular template layer.
