In the study, with wavelength of 365, 405 and 435 nm LED light illumination is the evaluated by photocurrent-voltage (PC-V) measurements at different aperture size, LED light power and duty of cycle square waves of ac signal in In-Ga-Zn oxide (IGZO) Light-addressable potentiometric sensor (LAPS).

 

Carrier induced hydrogenation (CIH) is one solution for light induced degradation. The mechanism of CIH process is the passivation of B-O related defects by hydrogen atoms. Here, we investigated the effect on the enhanced conversion efficiency by the amount of hydrogen effused from the rear SiNx:H layers.

 

In this conference, we present a heterojunction photodetector based on a hybrid copper oxide nanoclusters (Cu2O/CuO NCs)/zinc oxide nanorods (ZnO NRs) structure. Copper oxide NCs and ZnO NRs are respectively deposited on an indium tin oxide (ITO)-coated glass by hydrothermal method and pulsed-laser deposition (PLD).

 

We developed method to grow quasi-two-dimensional perovskite single crystals.The single crystal is directly grown on hole transport layer,VB-FNPD,and we control thickness of single crystal to 10μm.Adjusting ratio of ions in the precursor solution,we can obtain thin-film crystals with vertically oriented 2D stacked structure.The highest conversion efficiency achieve up to 15.50%.

 

Formamide iodide (FoAI) was synthesized and applied as an additive for FAPbI3 based perovskite solar cells (PSCs). FoAI additive improved the performance of PSCs by inhibiting formation of δ-FAPbI3 which deteriorates the performance of PSCs. We believe FoAI is a promising additive to boost the performance of PSCs.

 

The purpose of this study is to enhance the perovskite stability by 2D/3D stacked perovskite layer. We incorporated SCN- anion into FA0.9Cs0.1PbI3, further deposited large-size on SCN-based perovskite to improve the stability of the perovskite solar cells.

 

We spin-coat a layer of methylammonium chloride (MACl) on the perovskite active layer in order to improve efficiency for indoor applications. These surface treatments can not only increase the bandgaps and the open-circuit voltages but also improve PCEs from26.4% to 30.5% at 1000 lux under indoor lighting conditions.

 

In this conference, we present a photocathode based on a hybrid copper oxide (Cu2O)/zinc oxide nanorods (ZnO NRs) heterojunction structure. Copper oxide and ZnO NRs are respectively deposited on an indium tin oxide (ITO)-coated glass by chemical bath deposition and hydrothermal method.

 

In this study, the chemical solution method was used to prepare one-dimensional ZnO nanorod photoelectrodes, which were subsequently used in dye-sensitized solar cells (DSSCs). The effects of ZnO nanorods (NRs) on the dye adsorption performance of DSSCs were investigated by growing ZnO NRs with varying lengths as photoelectrodes.

 

Solution process and sandwich evaporate technique (SET) are used to fabricate MAPbI3 perovskite solar cells doped with chloride ion, respectively. MAPbIxCl3-x solar cells fabricated by SET and solution process both perform well. We have successfully produced chlorine containing perovskite solar cell with a high crystallinity and high efficiency of 15.1%.

 

Integrating an efficient perovskite photodiode with high-purity color filters, we achieved PVSK color PDs with LDRs over mesopic vision and demonstrated highly color recognition beyond human eye. We also designed a surface phase-matched transmission enhancement top electrode−Ag/indium tin oxide (ITO) structure for highly efficient and aesthetic semitransparent organic photovoltaics.

 

Use DMSO to process the PEDOT:PSS interface to improve conductivity, and add a MAI buffer layer to avoid the metal Pb generated by the contact between PSS and PbI2. Through the improvement of the interface, the efficiency conversion efficiency is increased from 3.8% to 12.7%.
