Low-cost multijunction photovoltaic devices are the next step in the solar energy revolution. Adding a bottom junction with a low bandgap energy material through plasma-enhanced chemical vapour deposition (PECVD) processing could provide a low-cost boost in conversion efficiency. A logical candidate for this low-bandgap material is germanium. A...

An ethanol gas sensor based on carbon nanofibers (CNFs) with various densities and nanoparticle functionalization was investigated. The CNFs were grown by means of a Plasma-Enhanced Chemical Vapor Deposition (PECVD), and the synthesis conditions were varied to obtain different number of fibers per unit area. The devices with a larger density of...

Amorphous and nano-crystalline germanium is of potential interest for a wide range of electronic, optical, opto-electronic and photovoltaic applications. In this work the influence of deposition temperature on hydrogenated germanium (Ge:H) films was characterized, using over 200 Ge:H and over 70 SiGe:H films. The demonstrated temperature...

The development in solar cells began with wafer based cells, also called the first generation photovoltaic technology. Most of these wafer based cells were made of crystalline silicon. As a crystalline silicon cell must be relatively thick to absorb most of the incoming energy, the second generation (thin film solar cells) was introduced. In the...

For the far majority of current photovoltaic devices, photons with an energy below 1.1eV are not utilized. Adding a Plasma Enhanced Chemical Vapor Deposition (PECVD) processed germanium bottom cell to a multi-junction device has the potential to provide a low-cost boost in conversion efficiency by utilizing a part of this spectral range below 1...

Doped layers are a determining factor for the performance of photovoltaic devices such as silicon heterojunction and thin film silicon solar cells. The material properties of doped hydrogenated amorphous/nanocrystalline silicon-oxide (a/nc-SiO X≥0 :H) films processed by plasma-enhanced chemical vapor deposition generally exhibit a tradeoff...

Low-cost multijunction photovoltaic devices are the next step in the solar energy revolution. Adding a bottom junction with a low bandgap energy material through plasma enhanced chemical vapor deposition (PECVD) processing could potentially provide a low-cost boost in conversion efficiency. A logical candidate for this low bandgap material is...

The maximal conversion efficiency on a single pn-junction solar cell is calculated to be 33.7% at a band gap energy of 1.34 eV. The main reasons for this maximum are the non-absorption of low energy photons and the thermalization of high energy photons. To counter this, multijunction devices can be constructed to make optimal use of the spectral...

The poly-Si IBC topology is one of the most promising silicon solar cell designs and has already achieved >26% efficiency. In this work we optimise the front surface field (FSF) and apply rear hydrogenation to the poly-Si IBC structure developed by the TU Delft PVMD group. An investigation is also made of a PECVD tunnel oxide as a replacement...

We fabricated horizontal slot waveguides using two low temperature deposition techniques ensuring the full compatibility of the processes with CMOS technology. Slots width as thin as 45 nm with smooth slot surfaces can easily be fabricated with simple photolithographic steps. Fundamental TM-like slot mode in which the E-field is greatly enhanced...
