Using Photocurrent imaging technique to study the stability mechanism of perovskite solar cell in humid air

Using Photocurrent imaging technique to study the stability mechanism of perovskite solar cell in humid air Organic-inorganic perovskite (PVSK) solar cells have shown tremendous improvement in the past few years and are comparable to the best commercial solar cell technologies. The instabilities in the materials and devices are due to reactions with water. To date, PVSK solar cell degradation only has been investigated by monitoring the current-voltage (J-V) curves as a function of t...

Using Solar Simulator light-dependent-techniques to analyze bi-molecule recombination in OPV

Using Solar Simulator light-dependent-techniques to analyze bi-molecule recombination in OPV. Recently, L. Zhong et al. demonstrate highly efficient ternary norfullerene OPV with two polymer donors and an organic acceptor. The results indicate that adding proper amount (20%) PTB7-Th polymer in the polymer donor could effectively improve in the ternary OPVs. Figure To illustrate the increasing of is due to the suppression of bimolecular recombination by PTB7-Th, they ...
