Correlating light-induced deep defects and phase segregation in mixed-halide perovskites

Quentin Thomas Jeangros, Christian Michael Wolff, Jakub Holovsky, Peter Joseph Fiala, Xin Yu Chin

Mixed-halide perovskites are highly promising materials for tandem solar cells. The phenomenon of phase segregation, however hinders their application. Here, we combine Fourier-Transform photocurrent spectroscopy with photoluminescence and current density- ...

Mechanisms of Plasma-Seed Treatments as a Potential Seed Processing Technology

Ivo Furno, Alan Howling, Alexandra Waskow

Plasma treatments are currently being assessed as a seed processing technology for agricultural purposes where seeds are typically subjected to pre-sowing treatments to improve the likelihood of timely and uniform germination. The aim of this review is to ...

Transferability of the light-soaking benefits on silicon heterojunction cells to modules

Christophe Ballif, Jonas Geissbühler, Matthieu Despeisse, Mathieu Gérard Boccard, Jean Cattin

We investigate the effect of light soaking and forward electric bias treatment on SHJ solar cells and modules, and in particular the influence of the thermal treatment occurring during lamination. A substantial performance increase is observed after electr ...

Seed Selection for Successful Fuzzing

Mathias Josef Payer

Mutation-based greybox fuzzing-unquestionably the most widely-used fuzzing technique-relies on a set of non-crashing seed inputs (a corpus) to bootstrap the bug-finding process. When evaluating a fuzzer, common approaches for constructing this corpus inclu ...

Stability in 3D and 2D/3D hybrid perovskite solar cells studied by EFISHG and IS techniques under light and heat soaking

Mohammad Khaja Nazeeruddin, Sanghyun Paek, Kyung Taek Cho, Zubair Ahmad

We investigate the effect of temperature and light soaking on the stability and charge carrier behavior in triple cation 3-Dimensional (3D) and 2-Dimensional (2D)/3-Dimensional perovskite solar cells (PSCs) using electric field induced second harmonic gene ...

Degradation analysis in mixed (MAPbI(3) and MAPbBr(3)) perovskite solar cells under thermal stress

Mohammad Khaja Nazeeruddin, Sanghyun Paek, Zubair Ahmad

The current study provides an insight into the thermal stability of perovskite solar cells (PSCs) and the factors causing their degradation. To this end, a systematic stability study was carried out on n-i-p type perovskite solar cells involving mesoporous ...

Template-Assisted Formation of High-Quality alpha-Phase HC(NH2)(2)PbI3 Perovskite Solar Cells

Mohammad Khaja Nazeeruddin, Yong Ding, Xuehui Liu, Cheng Liu

Formamidinium (FA) lead halide (alpha-FAPbI(3)) perovskites are promising materials for photovoltaic applications because of their excellent light harvesting capability (absorption edge 840 nm) and long carrier diffusion length. However, it is extremely di ...

Photoinduced Lattice Symmetry Enhancement in Mixed Hybrid Perovskites and Its Beneficial Effect on the Recombination Behavior

Ulf Anders Hagfeldt, Hui-Seon Kim

The strategy of mixing cations and halides in hybrid organic lead halide perovskites has recently been shown to be very successful in achieving high efficiency with long-term perovskite solar cell stability. In this study, the effect of photoexcitation on ...
