Al0.2Ga0.8As photovoltaic solar cells have been monolithically grown on silicon substrates by Molecular Beam Epitaxy. Due to the 4% lattice mismatch between AlGaAs and Si, Threading Dislocations (TDs) nucleate at the III-V/Si interface and propagate

A model, adapted from the Shockley–Queisser detailed balance model to tandem solar cells with a monolithically grown GaAs x P 1 −x top junction on a Si bottom junction, has been developed. Updated data have been used for the absorption spectrums.

We present an experimental method to quantify the series resistance R a-Si/ITO through the a-Si:H layers and the a-Si:H/ITO interface on test structures. In order to optimize R a-Si/ITO , we apply different a-Si:H and ITO deposition parameters. We fi

We present an analytical model for the current transport in polycrystalline (poly)Si/interfacial oxide/monocrystalline ( c)-Si base junctions, which consistently describes the symmetrical behavior of an n+ poly-Si emitter/ p c-Si base and p+ poly-Si

Aluminum oxide provides an excellent surface passivation on p - and n -type crystalline silicon. On n -type silicon, however, the effective excess carrier lifetime τ eff is often found to be injection dependent. Our experimental results show that, i

Laser doping of crystalline Si (c-Si) using highly doped Si nanoparticles (NPs) as the dopant source is investigated. For this purpose Si NPs are deposited onto c-Si substrates from dispersion using a spin coater and subsequently laser annealed by sc

We show the degradation of the front surface passivation by rear-side laser processing of thin silicon solar cells when using a laser with a pulse length of 8 ps. 45-μm-thick back-contact back-junction monocrystalline silicon solar cells show an ene

We use SENTAURUS DEVICE simulation to investigate the effect of “passivated emitter and rear cell” (PERC) and “passivated emitter and rear, totally-diffused” (PERT) device architecture on the solar cells’ weak light performances. Injection-

A model, derived from the detailed balance model from Shockley and Queisser, has been adapted to monolithically grown GaAsP/Si tandem dual junction solar cells. In this architecture, due to the difference of lattice parameters between the silicon bot
