- 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.… Expand
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… Expand
Silicon heterojunction solar cell with passivated hole selective MoOx contact
- C. Battaglia, S. Nicolas, +4 authors A. Javey
- Physics
- 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… Expand
Infrared light management in high-efficiency silicon heterojunction and rear-passivated solar cells
- Z. Holman, M. Filipič, +4 authors 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,… Expand
Organometallic Halide Perovskites: Sharp Optical Absorption Edge and Its Relation to Photovoltaic Performance.
