Thin-film silicon technology creates electricity out of micrometer thick silicon absorber layers, which makes this technology less material heavy compared to classic crystalline technology. This advantage can be further exploited with the transition towards flexible thin-film technology, where the non-modular cost can be further reduced compared...

Single junction solar cells have a theoretical efficiency limit of 33.1% due to spectral mismatch. To overcome this, multi-junction devices are generally fabricated with two or more junctions, so as to achieve better energy conversion efficiency by optimum spectral utilization. The c-Si bottom cell of a thin-film Si triple-/quadruple-junction...

In this work we focus on texturing Al substrate in order to employ the modulated surface texturing approach for thin-film, flexible, micromorph solar cells. We deployed two different methods to induce micro-craters in Al foil, i) bare Al etching by KOH and ii) AZO sacrificial layer etched in KOH. After modelling the etching kinetics of KOH on...

Single junction solar cells have a theoretical efficiency limit of 33.1% due to spectral mismatch. To overcome this limitation, two or more single junction cells with different bandgaps can be coupled together to achieve higher energy conversion efficiency by optimum spectral utilization. In this work, thin film silicon-based alloys are used to...

Roerink, Steven (author)
Multi-junction solar cells with Si alloys have true potential for high conversion efficiency, because of the spectrum splitting capability. For optimal spectral utilization, a multi-junction silicon based device needs a silicon alloy with a bandgap between that of nc-Si (1.1 eV) and a-Si (1.8 eV). a-SiGe:H has a tunable bandgap between 1.4-1.6...

Current photovoltaic (PV) industrial chain mainly serves the conventional utility-scale PV power stations. Rigid and opaque silicon-based PV modules domain the market so far. As distributed PV capacities expand, PV modules tend to be integrated with existing infrastructures (mostly, buildings). To adapt with the building environment, innovative...

Kothandaraman, Radha Krishnan (author)
Single junction solar cells suffer from two primary loss mechanisms due to spectral mismatch: thermalisation and non-absorption losses. A photon with energy greater than the bandgap of the solar cell can be absorbed to excite an electron-hole pair and the excess energy received is released as heat constituting thermalisation losses. On the other...

A soft deposition method for incorporating surface plasmon resonant metal nanoparticles within photovoltaic devices was studied. This self-assembly method provides excellent control over both nanoparticle size and surface coverage. Films of spherical Ag nanoparticles with diameter of ?100 nm were fabricated by depositing size-selected aerosols...

Hydrogenated Amorphous Silicon (a-Si:H) is a very promising solar cell material with a good potential to use in many applications, as it is cheap to produce, light-weight and flexible. However, upon prolonged exposure to light, the layers suffer from both metastable and irreversible changes (the Staebler-Wronski effect) that have a bad effect on...
