Chemical Trend of Nonradiative Recombination in Cu(In,Ga)Se2 Alloys

Nonradiative recombination in Cu(In,Ga)Se2 (CIGS) solar cells has long been attributed to the antisite defects MCu (M = In, Ga), but the underlying mechanism is still elusive. Using rigorous first-principles calculations, we demonstrate that the antisites ...

Temperature‐dependent performance of silicon heterojunction solar cells with transition‐metal‐oxide‐based selective contacts

Mathieu Gérard Boccard, Julie Amandine Dreon

The temperature coefficient (TC) is an essential figure of merit to accurately evaluate solar cell performance at various operating temperatures and hence enabling the comparison between different cell technologies. Recently, solar cells that use passivati ...

Transient Photovoltage Measurements on Perovskite Solar Cells with Varied Defect Concentrations and Inhomogeneous Recombination Rates

Wolfgang Richard Tress, Zaiwei Wang, Brian Irving Carlsen, Firouzeh Ebadi Garjan

In all kinds of solar cells, transient photovoltage (TPV) decay measurements have been used to determine charge carrier lifetimes and to quantify recombination processes and orders. However, in particular, for thin-film devices with a high capacitance, the ...

Optoelectronic Properties of Layered Perovskite Solar Cells

Mohammad Khaja Nazeeruddin, Sanghyun Paek, Yonghui Lee, Kyung Taek Cho

Herein, the optoelectronic properties of interface-engineered perovskite 2D|3D-heterojunction structure solar cells are reported. The reciprocity theorem is applied to determine the maximum open-circuit voltage (V-oc) the device can deliver under solar ill ...

Injection-dependent lateral resistance in front-junction solar cells with nc-Si:H and a-Si:H hole selective contact

Christophe Ballif, Mathieu Gérard Boccard, Jan Haschke, Jean Cattin

We investigate the role of lateral transport of minority carriers in the wafer for front-junction solar cells. The study is based on two silicon heterojunction solar cells with p-type amorphous (a-Si), and nanocrystalline (nc-Si) silicon as hole selective ...

Performance of perovskite solar cells under simulated temperature-illumination real-world operating conditions

Michael Graetzel, Wolfgang Richard Tress, Ulf Anders Hagfeldt, Konrad Domanski, Essa Awadh R Alharbi, Brian Irving Carlsen, Anand Agarwalla

Since reaching 20% efficiency, research in perovskite photovoltaics has shifted from a race for efficiency to a race for stability. For efficiency, the standard test conditions set the rules for the race. However, the term 'stability' is used very broadly ...

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

Wolfgang Richard Tress, Simone Meloni, Björn Niesen, Juan-Pablo Correa-Baena, Zaiwei Wang, Chien-Jen Yang, Mozhgan Yavari, Firouzeh Ebadi Garjan

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 ...
