Newest technology solar panels – Sun energy production. A new type of photovoltaic cell on the market at the end of 2018. The use of the material perovskite (calcium titanium oxide, CaTiO) in the conversion of light into electrical energy has undergone rapid development in recent years, as it turns out. According to researchers and market parties, PV cells made from perovskite can turn the photovoltaic panel market with a magnitude of 42 billion dollars upside down. That writes the Bloomberg news service.
Cells as a coating
Perovskites can be mixed with liquids and applied to a wide range of materials. Bloomberg sketches a future where cells are applied as a coating – sprayed or printed – on windows, buildings and vehicles. And that at prices that could be much lower than the current solutions for Sun power.
A perovskite cell is a type of cell which includes a perovskite structured compound, most commonly a hybrid organic-inorganic lead or tin halide-based material, as the light-harvesting active layer. Perovskite materials such as methylammonium lead halides are cheap to produce and simple to manufacture
Newest technology PV modules – Perovskite promising. The Perovskite material was ranked seventh in the top 10 of promising technologies by the World Economic Forum in 2016.
Universities and companies around the world are exploring the possibilities of applying perovskite in cells and panels. “The road ‘from lab to fab to the roof’ is, however, long and full of stumbling blocks.
Efficiency of perovskite
In 2006 it became clear that perovskite is useful for converting sunlight into electrical energy. A breakthrough came in 2012 when the return was above 10 percent. In the lab, yields of more than 20 percent are now being achieved. With this, the yield of silicon cells is slowly approaching, which is around 25 percent and hardly makes any progress.
Newest technology photovoltaic panels – Metal Wrap Through
Metal Wrap Through
Cells generate sustainable energy using sunlight. With new generation techniques come improvements that generate more electricity. It is recognizable that the power (wattpeak) and the efficiency (efficiency) of a panel increase.
The next step for large-scale production of photovoltaic modules are technologies where the power is harvested through contacts at the back of the cell, which are connected to a conductive substrate. Such cells are also called backside-contacted cells, in short ‘back contact’. The most promising back-contact technique is ‘Metal Wrap Through’, or MWT.
Three important advantages
- Because ribbons are no longer needed, an important stress factor on cells has disappeared, as a result of which microcracks are prevented in cells. MWT also makes approximately 1% of the area available for the sun. Three ribbons less saves so soon three percent production of renewable energy.
- 25 contact points per cell (instead of 3 busbars) is a considerable improvement of the reliability of the panel and contributes to a lower NOCT with a lower serial resistance.
- MWT cells have a more attractive design
Newest technology PV panels – Panasonic HIT Heterojunction technology
A cell is a hybrid PV cell that combines ultra-thin amorphous silicon and high-quality monocrystalline silicon into a layered construction that is developed using Panasonic’s proprietary technology. The layers with i-type amorphous silicon are in the HIT cell placed between the crystalline silicon wafer and the layers p- and n-type amorphous silicon. The HIT can be compared to conventional crystalline silicon cells structure the defective minimize surface area in photovoltaic modules, which significantly reduces energy loss.
