Instability of p-i-n perovskite solar cells under reverse bias

Christophe Ballif, Sylvain Nicolay, Quentin Thomas Jeangros, Laura Ding, Florent Sahli, Chien-Jen Yang, Fan Fu, Arnaud Walter, Peter Joseph Fiala, Daniel Anthony Jacobs, Marion Solange Madeleine Dussouillez

Partial shading can trigger permanent damage in photovoltaic modules because the illuminated solar cells drive the shaded cells into reverse bias. Under reverse bias conditions, perovskite solar cells have been shown to degrade quickly due to processes tha ...

How far does the defect tolerance of lead-halide perovskites range? The example of Bi impurities introducing efficient recombination centers

Simone Meloni, Wolfgang Richard Tress, Björn Niesen, Juan-Pablo Correa-Baena, Zaiwei Wang, Chien-Jen Yang

One of the key properties of lead-halide perovskites employed in solar cells is the defect tolerance of the materials, in particular regarding intrinsic point defects, which mainly form shallow traps. Considering that high luminescence yields and photovolt ...

Multiple Charge Transfer States in Donor-Acceptor Heterojunctions with Large Frontier Orbital Energy Offsets

Björn Niesen, Chien-Jen Yang, Xiao Liu

In this work, we demonstrate several organic amorphous donor-acceptor systems that exhibit sub-bandgap features over a more than 2 eV spectral range. An in-depth study of one of these systems, NPB:HAT-CN (NPB is N,N'-di(1-naphthyl)-N,N'-diphenyl-(1,1'-biph ...
