Effects of 5 MeV electron irradiation on deep traps and electroluminescence from near-UV InGaN/GaN single quantum well light-emitting diodes with and without InAlN superlattice underlayer

Nicolas Grandjean, Jean-François Carlin, Raphaël Butté, Mauro Mosca, Camille Haller

The electrical properties, electroluminescence (EL) power output and deep trap spectra were studied before and after 5 MeV electron irradiation of near-UV single-quantum-well (SQW) light-emitting diodes (LED) structures differing by the presence or absence ...

Development of an inorganic cesium carbonate-based electron transport material for a 17% power conversion efficiency perovskite solar cell device

Mohammad Khaja Nazeeruddin, Iwan Zimmermann, Brahim Aissa

A low-temperature solution process technique is employed to develop an inorganic cesium carbonate (Cs2CO3) as an electron transport material for inorganic-organic hybrid double cation (FAPbI(3))(0.85)(MAPbBr(3))(0.15) perovskite solar cells, as an alternat ...

A cost-device efficiency balanced spiro based hole transport material for perovskite solar cells

Mohammad Khaja Nazeeruddin

Although spiro-MeOTAD 1 is a superior hole-transporting material (HTM) commonly employed in perovskite solar cells (PSC), its high cost is one of the major issues holding back commercialization, which has not been resolved to-date. In this article we intro ...

Influence of the Subcell Properties on the Fill Factor of Two-Terminal Perovskite-Silicon Tandem Solar Cells

Christophe Ballif, Mathieu Gérard Boccard

The performance of a tandem solar cell depends on the performance of its constituting subcells. Although this dependency is theoretically straightforward for open-circuit voltage (V-oc) and short-circuit current, it is indirect for fill factor (FF) and thu ...

Optimization of front SiNx/ITO stacks for high-efficiency two-side contacted c-Si solar cells with co-annealed front and rear passivating contacts

Christophe Ballif, Franz-Josef Haug, Xavier Niquille, Andrea Ingenito, Sylvain Nicolay, Frank Meyer

In this contribution, we present an electron selective passivating contact metallised with a low temperature process to target front side applications in crystalline silicon (c-Si) solar cells. In addition to an interfacial silicon oxide (SiOx) and an in-s ...
