The fundamental operation mechanisms of nc-SiO_X≥0:H based tunnel recombination junctions revealed

Two terminal multi-junction (MJ) photovoltaic (PV) devices are well established concepts to increase the solar-to-electrical power conversion in reference to single PV junctions. In multi-junction PV devices two consecutive sub-cells are interconnected using a tunnel recombination junction (TRJ) in which the light excited holes of one sub...

Broadening the Thin-Film Horizon: Opto-­electrical modelling of a monolithic Perovskite/CIGS tandem solar cell

The need for more efficient, cheaper, easily producible solar cells is growing as this combination of attributes can decrease the levelized cost of energy (LCOE). A two­terminal (2T) Perovskite and galliuminidium­gallium­selenide (Pvk/CIGS) tandem cell is an excellent candidate, as it can have a power conversion efficiency (PCE) of +30%, can be...

Experimental demonstration of poly-Si/SHJ hybrid tunnel-IBC c-Si cells

Interdigitated back-contacted solar cell (IBC) is a successful high-efficiency solar cell concept. Without a metal grid at the front side, the metal shading loss is eliminated. However, the fabrication process of an IBC cell is much more complicated than that of a FBC cell. Within the PVMD group, two poly-Si carrier-selective passivating...

Thin-film silicon triple junction solar cell for solar fuels

The ever increasing installed capacity of renewable, sustainable energy is essential in order to keep the earth<br/>habitable. However, the intermittent nature of solar and wind energy do not strictly follow human energy<br/>demands. Therefore an energy of sufficient magnitude buffer is essential to provide a constant supply of<br/>energy that...
