Enhancing the open-circuit voltage (VOC) is one way to increase the efficiency of organic solar cells. In cells with the polymer poly(2-(5-(5,6-bis(octyloxy)-4-(thiophen-2-yl)benzo[c][1,2,5]thiadiazol-7-yl)thiophen-2-yl)-9-octyl-9H-carbazole) (HXS-1)

GaInP/GaAs//Si solar cells with three active p-n junctions were fabricated by surface activated direct wafer bonding between GaAs and Si. The direct wafer bond is performed at room temperature and leads to a conductive and transparent interface. This

Silicon-carbon (Si-C) thin films play a key role in many technological applications such as hard coatings, high-power electronics, and photovoltaics. In photovoltaics in particular annealed Si-C thin films containing Si quantum dots are used to devel

Solar Energy Materials and Solar Cells
Upconversion of sub-band-gap photons promises to increase solar cell efficiencies by making these photons useful. In this paper, we investigate the application of β-NaYF4:20% Er3+ to silicon solar cells. We determine the external quantum efficiency

In this paper, we present results of optical simulations on the absorption of nanowires. The simulation was performed with rigorous coupled wave analysis to determine the potential of nanowires for use in a new kind of nanostructured solar cell. The

In this paper we present detailed balance simulations which determine the material parameters required to produce hot carrier solar cell (HCSC) annual energy yields comparable with that of multi-junction (MJ) systems. We demonstrate that HCSCs are le

In this paper, we present laminated concept for indium tin oxide (ITO)-free organic solar cells (OSC). This concept omits the need of electrode deposition on top of organic layers and thus gives freedom of choice for the electrodes and the correspond

The Suns-VOC technique is used to acquire pseudocurrent-voltage (JV) characteristics of solar cells which are unaffected by their series resistance and, therefore, only reflect generation and recombination. It is well established for inorganic solar
