Efficient nanocoax-based solar cells

Christophe Ballif, Franz-Josef Haug, Thomas Söderström

The power conversion efficiency of most thin film solar cells is compromised by competing optical and electronic constraints, wherein a cell must be thick enough to collect light yet thin enough to efficiently extract current. Here, we introduce a nanoscal ...

Evaluation of Cost-Effective Technologies for Highly Efficient Silicon-Based Solar Cells

Luca Gautero

The work underscores the feasibility of highly efficient silicon solar cell structures manufactured with high throughput machines. The main challenge consists in the implementation of more performant structures of intrinsic higher complexity. These structu ...

Using Nanocavity Plasmons to Improve Solar Cell Efficiency

Stefan Guldin

Although in principle very promising, photovoltaic technology has so far failed to deliver robust high efficiency modules at affordable prices. Despite considerable research, high efficiency silicon based cells remain expensive, while the more recent organ ...
