Now researchers from the Centre for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW), Martin Luther University Halle-Wittenberg (MLU) and the Helmholtz-Zentrum Berlin (HZB) have identified a way to convert more sunlight into electricity in CIGS cells. Your personal data will only be disclosed or otherwise transmitted to third parties for the purposes of spam filtering or if this is necessary for technical maintenance of the website. Computer simulations showed that increased recombination at electrically active grain boundaries within the CIGS layer constitutes a significant loss mechanism. These solar cells are commonly known as a copper indium gallium diselenide [Cu(In x Ga 1-x)Se 2], or CIGS, cells. This is technically possible through additional additives in the CIGS layer, the adaptation of the substrate material, or via an optimized temperature balance during coating. The researchers claimed that a theoretical efficiency of around 33% is possible for CIGS thin-film solar cells. Cadmium telluride (CdTe) solar panels. Zinc oxide, formed on the transparent conductive oxide (TCO) layer on top of the CIGS cells is susceptible to damage by moisture. Any other transfer to third parties will not take place unless this is justified on the basis of applicable data protection regulations or if pv magazine is legally obliged to do so. They published their findings in Nature Communications in August 2020. CIGS has an exceptionally high absorption coefficient of more than 10 5 /cm for 1.5 eV and higher energy photons. Cu(In,Ga)Se2 (CIGS) solar cells attract intense interest both in research and industry fields due to their high power conversion efficiencies, low costs, and high stabilities.

The project gathers thirteen institutions aiming to work on lowering the production cost of thin-film solar cells by developing advanced solar cell architectures. The efficiency of thin-film solar cells based on copper, indium, gallium and selenium (CIGS) semiconductors has improved to more than 23% in recent years, thanks to ongoing research. The CIGS solar cells were fabricated using the three stage co-evaporation process []. The benefits of CIGS solar cells include: 1. Their conversion efficiency on a glass substrate is now approaching 20%. Hold Ctrl or Cmd to select multiple editions. CIGS (copper-indium-gallium-selenide) solar cells are compound thin-film solar cells and the most established alternative to silicon solar cells. “Some of the losses occur at the boundaries between the individual CIGS crystals of the solar cell,” said project manager Wolfram Witte from ZSW. Research team pinpoints potential for improving CIGS solar cells The efficiency of today’s thin-film solar cells with the CIGS compound semiconductor has already topped the 23 percent mark, but now a further increase looks to be within reach. “What needs to be done to further improve the efficiency of CIGS thin-film solar cells and modules is to reduce the density of the electrically active grain boundaries and produce CIGS layers with larger grains,” says Witte. The discrepancy arises from loss mechanisms in the CIGS solar cell, which can occur in the functional layers, but also at several of the cell interfaces. Funded by the BMWi, the German Federal Ministry for Economic Affairs and Energy, this research venture ended in 2020 after a run of around three and a half years.

Furthermore, the report also provides the qualitative results of … The absorber (the CIGS layer) in a solar cell is where the action is. With its tunable bandgap, being able to be transparent and flexible, it is widely preferred for thin-film applications. Positive and negative electrical charges can neutralise each other at these grain boundaries, some of which are electrically active,” says project manager Wolfram Witte from the ZSW. In thin-film solar technology a large glass panel forms the base material, on which a relatively thin layer of 1 to 2 μm of photoactive compound is applied. Tandem design: A tunable bandgap allows the possibility of tandem CIGS devices. The real microstructure of the cell was used with the experimentally obtained values ​​of the various analysis methods as input parameters for the two-dimensional simulation, the researchers said. Solar cells can be categorized according to the applied production process and used materials, for example in crystalline and thin-film solar cells. The project is working on thin film solar cells based on Cu(In,Ga)Se2, or CIGS, because this technology is low weight, low light efficienct, flexibile, has great aesthetics, and has reasonable and competitive production costs. Fig. The results of this investigation reveal how manufacturers of CIGS thin-film solar cells can achieve even higher efficiencies, it is reckoned. Beside the toxicity of Cd, the main drawback of CdS is its relatively narrow band gap (2.4 eV), which can lead to the current loss due to parasitic absorption. The layer stack consists of: 400 nm direct current (DC) sputtered Mo, CIGS with varying thickness and composition, 50 nm chemical bath deposited CdS, 60 nm DC sputtered intrinsic zinc oxide, 210 nm DC sputtered aluminum-doped zinc-oxide and a metal current-collecting grid (20 nm Ni, 600 nm Ag, 20 nm … “Some of the losses occur at the boundaries between the individual CIGS crystals in the solar cell. Our CIGS modules. Vietnam is a rapidly developing country. Traditional solar cells use silicon in the n-type and p-type layers.

Capacity: 50 MW/yr. “This reduces the cell's performance.”. Although laboratory-scale cell efficiencies have exceeded 20%, commercial CIGS modules typically have efficiencies between 12% and 14%. Solar conversion efficiencies of over 20% have recently been achieved in CIGS pv magazine offers daily updates of the latest photovoltaics news. One company CIGS is an acronym for Cu(In,Ga)Se 2.This semiconductor material is an excellent light absorber, which is auto-doped and high quality CIGS is therefore always p-type. The analysis showed that increased recombination at electrically active grain boundaries within the CIGS layer contributes to significant losses. Now researchers from the Centre for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW), Martin Luther University Halle-Wittenberg (MLU) and the Helmholtz-Zentrum Berlin (HZB) have identified a way to convert more sunlight into electricity in CIGS cells.
