Oxford Photovoltaics postpones the market launch of its tandem cell by one year
The British company Oxford Photovoltaics hopes to set up a production unit of 250 MW per year by the end of 2020 to produce perovskite-based tandem cells.
To achieve this, in March, the company raised £31m ($40m) and Meyer Burger took an 18.8% stake in the capital.

Quel est le futur de la technologie N ?
Quel est le futur de la technologie N ?
Début 2018, de nombreux fabricants annonçaient des plans d'expansion de l'hétérojonction (HJT), ce qui développait la technologie N. Les décisions chinoises du 31 mai ont arrêté les plans d'expansion. Ensuite, le prix des produits P a chuté en liaison avec la réduction des coûts et les progrès de l'efficacité, alors que le marché des cellules de type N a continué d'enregistrer des coûts et des prix de vente élevés.

Profitability of a power plant in Spain built without subsidies
The terms and conditions of the 175 MW Don Rodrigo solar power plant near Seville (Spain) have been presented by its developer, the German company BayWa r.e. The project is due to be completed in 2012, with construction due to be completed in the second quarter of 2019, and has just been sold. It is being built without subsidies, which allows the developer to be independent of any political developments in a very sunny region. Above all, it is an opportunity to

Presentation of the heterojunction cell
In order for solar energy to establish itself in a world without feed-in tariffs, new high-efficiency cells are needed in conjunction with cost reduction.
Meyer Burger presents its current solution (heterojunction) for such cells.
Heterojunction cell technology (HJT) combines the advantages of

Presentation of panels made up of half cells
The multiplication of busbars (bars for transporting electricity) and the appearance of half-cells both serve to increase the power of the panels. The increase in the number of bars (the metallic electrical connectors that can be seen on the front and/or back of each cell) reduces the resistance between cells. It's a bit like adding more lanes to a motorway: more vehicles (electrons) can use it simultaneously. Manufacturers are reaching 5 bars, but they are already talking about multi-bars. If there were 12 bars, there would be 12 lanes.
Half cells reduce current losses and increase the power of the panels from 5 to 15 Wp, depending on the number of half cells. In addition, the reduction of the current losses

Presentation of perovskite
Professor Mohammad Nazeeruddin only works on perovskite at the EPFL (Ecole Polytechnique Fédérale de Lausanne). The formula of this product is very simple: by combining it with just one other element, a solar cell is produced whose efficiency is comparable to that of silicon cells, but with a much lower production cost.
