Progress on Low-Temperature Pulsed Electron Deposition of CuInGaSe2 Solar Cells

Effect of Temperature on Electrical Parameters of Phosphorous Spin–on Diffusion of Polysilicon Solar Cells

Effects of temperature on electrical parameters of polysilicon solar cells, fabricated using the phosphorous spin-on diffusion technique, have been studied. The current density–voltagecharacteristics of polycrystalline silicon solar cells were measured in dark at different temperaturelevels. For this purpose, a diode equivalent model was used to obtain saturation current densi...

Progress in epitaxial deposition on low-cost substrates for thin-film crystalline silicon solar cells at IMEC

In recent years, research on epitaxial growth for photovoltaics became more important due to the increasing interest in thin-film silicon solar cells. Two significant challenges need to be resolved before this technique can become a competitive industrial alternative to the current dominating technology of bulk silicon solar cells: (i) the availability of a high-throughput and cost-effective ep...

Microstructure Analysis of Cdte/cds Thin-film Solar Cells for Optimization of Devices Fabricated at Low Temperature with Pulsed Laser Deposition

Low temperature fabrication of CdTe (1.25 μm)/CdS (120 nm) thinfilm solar cells was explored using in situ pulsed laser deposition (PLD) in order to control the CdTe grain morphology, crystallinity, and CdS/CdTe interface, which have proven to be crucial in CdTe/CdS solar cell performance. A comparative study was carried out on solar cells fabricated using PLD with the CdTe layer either grown d...

Investigations on Optoelectronic Properties of New low Gap Compounds Based on Pyrrole as Solar Cells Materials

In this paper theoretical study by using DFT method on three conjugated compound based on 2-styryl-5-phenylazo-pyrrole is reported. These dyes contain one carboxy, two carboxy and one sulfonic acid anchoring groups, the aim is to investigate their effects on the electronic structure. The theoretical knowledge of the HOMO and LUMO energy levels of the components is cannot be ignored in investiga...
