Shared Research program Perovskite based Solar Cells

The Shared Research Program Perovskite based Solar Cells and Modules (PSC) focusses on the newest generation solar cells. The absorber layer is based on perovskites, a group of materials named after the Russian mineralogist Lev Perovski. The efficiency of these solar cells developed rapidly over the last years and the verified efficiency records are approaching 24% already. The elements that form perovskite crystals are basic, not scarce and relatively easy to process. The deposition processes do not require low pressure, vacuum or high temperatures. This opens the possibility to produce at high velocity on flexible and transparant substrates. Altogether, perovskite based cells and modules can be highly efficient, low cost, flexible and customisable in size and shape.

Flexible and transparent

 

The research and development on Perovskite based Solar Cells (PSC) involves still fundamental issues and focuses on new material compositions for the absorber and its supporting device layers, specifically on innovative semi-transparent and translucent designs. These designs are primarily aiming at PSC application in a tandem or hybrid configuration together with other solar absorber materials, but will also enable transparent and bi-facial PSC module formation. Central issue is further to enable a PSC device lifetime that is acceptable for the desired application. Solliance specifically focuses its research on large volume, high production rate, solution based atmospheric processing of perovskite solar cells.

 

In this research we cooperate with leading industrial and academic partners. Together we form a top-league joint research team with a proven track record in equipment development. Solliance partners report record breaking cells, modules and tandems on a regular base and are invited speakers on this topic at international conferences.

Highlights and outlook

 

Some highlights in this program are:

  • Roll-to-roll equipment and processing to perovskite based solar cells. Together with partners like VDL and Holst Centre, we developed a unique roll-to-roll printing line, capable of multi-layer slot-die printing of solution based layers. Our team succeeded in producing a large number of flexible samples with a module efficiency of 12.6% and extraordinary low variation between the samples. Read more.
  • Tandem silicon perovskite module. The PSC can be made semi-transparent and combined with a traditional silicon wafer, a so called ‘tandem cell’. For a mini-module an efficiency of 23,9% recorded.
  • Flexible Perovskite CIGS tandem of 21,5%. Together with industrial partner MiaSole Hitech Corp. the bandgas of both absorbers were tuned to be as complementary as possible. This resulted in a high efficient flexible cell. Read more.
  • Translucent solar cells. Using advanced laser patterning we have developed translucent perovskite solar cell with an aperture efficiency of around 10%, in combination with translucent (meaning apparently transparent) properties.

 

The Solliance program roadmap is are focused on improved lifetime stability, atmospheric pressure solution based processing of modules and improved efficiency.
