Building Integrated Photovoltaics (BIPV): Review, Potentials, Barriers and Myths
- P. Heinstein, C. Ballif, Laure-Emmanuelle Perret-Aebi
- Engineering
- 14 June 2013
Abstract To date, none of the predictions that have been made about the emerging BIPV industry have really hit the target. The anticipated boom has so far stalled and despite developing and promoting…
Current Losses at the Front of Silicon Heterojunction Solar Cells
- Z. Holman, A. Descoeudres, C. Ballif
- Physics, ChemistryIEEE Journal of Photovoltaics
- 12 January 2012
The current losses due to parasitic absorption in the indium tin oxide (ITO) and amorphous silicon (a-Si:H) layers at the front of silicon heterojunction solar cells are isolated and quantified.…
Silicon heterojunction solar cell with passivated hole selective MoOx contact
- C. Battaglia, S. M. D. Nicolas, A. Javey
- Chemistry
- 17 March 2014
We explore substoichiometric molybdenum trioxide (MoOx, x < 3) as a dopant-free, hole-selective contact for silicon solar cells. Using an intrinsic hydrogenated amorphous silicon passivation layer…
Infrared light management in high-efficiency silicon heterojunction and rear-passivated solar cells
- Z. Holman, M. Filipič, C. Ballif
- Physics
- 4 January 2013
Silicon heterojunction solar cells have record-high open-circuit voltages but suffer from reduced short-circuit currents due in large part to parasitic absorption in the amorphous silicon,…
Transition between grain boundary and intragrain scattering transport mechanisms in boron-doped zinc oxide thin films
- J. Steinhauser, S. Faÿ, N. Oliveira, E. Vallat-Sauvain, C. Ballif
- Materials Science
- 4 April 2007
A comprehensive model for the electronic transport in polycrystalline ZnO:B thin films grown by low pressure chemical vapor deposition is presented. The optical mobilities and carrier concentration…

Efficient silicon solar cells with dopant-free asymmetric heterocontacts
- J. Bullock, M. Hettick, A. Javey
- Chemistry
- 25 January 2016
A salient characteristic of solar cells is their ability to subject photo-generated electrons and holes to pathways of asymmetrical conductivity-'assisting' them towards their respective contacts.…
