Overview and future perspective of Si tandem solar cells

open access: yesApplied Physics Express
Silicon solar cells are the most established solar cell technology and are expected to dominate the market also in the near future. As state-of-the-art silicon solar cells are approaching the Shockley–Queisser limit (32%–33%), stacking silicon solar ...

Organic tandem solar cells - modelling and predictions

open access: yes, 2006
Tandem combinations of organic photovoltaic devices are studied from an optical point of view. We unify coherent (wave-based) as well as incoherent (irradiance-based) light addition in our treatment of the incoming and reflected electromagnetic waves ...

Bulk Heterojunction versus Diffused Bilayer: The Role of Device Geometry in Solution p-Doped Polymer-Based Solar Cells [PDF]

open access: yes, 2012
We exploit the effect of molecular p-type doping of P3HT in diffused bilayer (DB) polymer solar cells. In this alternative device geometry, the p-doping is accomplished in solution by blending the F4-TCNQ with P3HT.

Leaftronics: Bio‐Fractal Scaffolds From Leaf Venation for Low‐Waste Electronics

open access: yesAdvanced Materials, EarlyView.
“Leaftronics” transforms naturally evolved leaf venation into quasi‐fractal scaffolds for sustainable electronics. Polymer‐infiltrated leaf skeletons can be used to fabricate ultra‐smooth, reflow‐ and thin‐film‐compatible decomposable substrates, while making the same lignocellulose networks conducting results in flexible transparent electrodes.

Matching of Silicon Thin-Film Tandem Solar Cells for Maximum Power Output

open access: yesInternational Journal of Photoenergy, 2013
We present a meaningful characterization method for tandem solar cells. The experimental method allows for optimizing the output power instead of the current.

Perovskite Solar Cells with Large-Area CVD-Graphene for Tandem Solar Cells

open access: yesThe Journal of Physical Chemistry Letters, 2015
Perovskite solar cells with transparent contacts may be used to compensate for thermalization losses of silicon solar cells in tandem devices. This offers a way to outreach stagnating efficiencies. However, perovskite top cells in tandem structures require contact layers with high electrical conductivity and optimal transparency.

Highly Anisotropic Quasi‐Direct Organic Metal Halide Hybrids: A Platform for Polarization‐Sensitive Optoelectronics

open access: yesAdvanced Materials Technologies, EarlyView.
One‐dimensional C4N2H14PbBr4 is shown to have a quasi‐direct electronic band structure and strongly anisotropic transport with polarized broadband emission. A GW/Bethe–Salpeter excited‐state force formalism, supported by polarized Raman and temperature‐dependent photoluminescence, identifies low–frequency Pb–Br phonons that drive ultrafast exciton self‐
