Light Management: A Key Concept in High-Efficiency Perovskite/Silicon Tandem Photovoltaics

Christophe Ballif, Florent Sahli, Daniel Anthony Jacobs

The remarkable recent progress in perovskite photovoltaics affords a novel opportunity to advance the power conversion efficiency of market-dominating crystalline silicon (c-Si) solar cells. A severe limiting factor in the development of perovskite/c-Si ta ...

Thermodynamically stabilized beta-CsPbI3-based perovskite solar cells with efficiencies > 18%

Mohammad Ibrahim Dar, Yang Li, Xiaoyan Wang, Ying Yang, Xingyu Gao

Although beta-CsPbI3 has a bandgap favorable for application in tandem solar cells, depositing and stabilizing beta-CsPbI3 experimentally has remained a challenge. We obtained highly crystalline beta-CsPbI3 films with an extended spectral response and enha ...

Appraisement of Crystal Expansion in CH3NH3PbI3 on Doping: Improved Photovoltaic Properties

Mohammad Khaja Nazeeruddin

Three-dimensional hybrid perovskite materials (CH3NH3PbI3) suffer from intrinsic instability owing to organic cation evaporation and ion migration. The inclusion of a large organic cation such as guanidinium has been probed to stabilize the structure. This ...

Impact of the Oxygen Flow during the Magnetron Sputtering Deposition on the Indium Tin Oxide thin films for Silicon Heterojunction Solar Cell

Christophe Ballif, Mathieu Gérard Boccard, Jan Haschke, Jean Cattin, Brahim Aissa, Akshath Raghu Shetty

We report on the optoelectronic properties of ITO layers deposited by DC sputtering, using different oxygen to total flow ratios [r(O-2) = O-2/Ar, ranging from 1% to 8%], for silicon heterojunction (SHJ) solar cell application. The depth profiling of the v ...

Hot Carrier Mobility Dynamics Unravel Competing Sub-ps Cooling Processes in Lead Halide Perovskites

Jacques-Edouard Moser, Andrés Burgos Caminal, Arun Aby Paraecattil, Juan Manuel Moreno Naranjo, Aurélien René Willauer

The outstanding photovoltaic performances of lead halide perovskite (LHP) thin film solar cells are due in particular to the large diffusion length of photocarriers. The mechanism behind this property and its dependence on the various anions and cations in ...

Electroluminescence Dynamics in Perovskite Solar Cells Reveals Giant Overshoot Effect

Wolfgang Richard Tress, Marius Franckevicius

High performance of both photovoltaic and electroluminescent devices requires low nonradiative recombination losses. In perovskites, such loses strongly depend on the carrier traps related to the mobile ions and vacancies, causing I-V hysteresis of solar c ...
