Understanding the Limit and Potential in Emerging Perovskite Solar Cells

Michael Graetzel, Wolfgang Richard Tress

In this contribution we give an overview of the recent development of metal-halide perovskite solar cells. We focus on the mixed electronic-ionic conductivity of this material, which causes hysteresis in the current-voltage curve. We discuss latest results ...

Efficient Monolithic Perovskite/Silicon Tandem Solar Cell with Cell Area >1 cm

Christophe Ballif, Arnaud Walter, Stefaan De Wolf, Björn Niesen, Jérémie Werner, Johannes Peter Seif, Luc Fesquet, Ching-Hsun Weng

Monolithic perovskite/crystalline silicon tandem solar cells hold great promise for further performance improvement of well-established silicon photovoltaics; however, monolithic tandem integration is challenging, evidenced by the modest performances and s ...

Semi-transparent perovskite solar cells for tandems with silicon and CIGS

Michael Graetzel, Norman Pellet, Julian Burschka

A promising approach for upgrading the performance of an established low-bandgap solar technology without adding much cost is to deposit a high bandgap polycrystalline semiconductor on top to make a tandem solar cell. We use a transparent silver nanowire e ...

CH3NH3PbI3 perovskite/silicon tandem solar cells: characterization based optical simulations

Christophe Ballif, Stefaan De Wolf, Björn Niesen

In this study we analyze and discuss the optical properties of various tandem architectures: mechanically stacked (four-terminal) and monolithically integrated (two-terminal) tandem devices, consisting of a methyl ammonium lead triiodide (CH3NH3PbI3) perov ...

Facile preparation of micron- and nano-scale textured master for nano-imprinting front electrode in thin-film silicon tandem cells with improved light trapping

Christophe Ballif, Franz-Josef Haug, Etienne Antoine Julien Moulin, Jinhua Huang

This paper reports a facile method to prepare a textured surface with combined micron- and nano-scale surface features, which is used as master for nano-imprinting process to obtain transparent front electrodes in thin-film silicon tandem cells. The micron ...

Elsevier2015

Solar energy represents an abundant (1000 W·m-2) and seemingly cheap source of energy. One way to tap it is to transform light into electricity with photovoltaic devices. Single junction solar cells presently reach 32% conversion yield under 1-sun illumina ...

We investigate the efficiency potential of organic-inorganic halide perovskite/crystalline silicon tandem solar cells, a new class of photovoltaic devices targeting long-term cost reductions by ultrahigh conversion efficiencies. Methyl ammonium lead triiod ...

Ieee-Inst Electrical Electronics Engineers Inc2014

Thin-film silicon solar cells are one possible answer to the increasing energy demand of today. Hydrogenated amorphous silicon (a-Si:H) plays a crucial role therein - as absorber layers, but also as doped layers to build p-i -n junctions. This thesis is de ...
