Product Name:
Organic solar cells
iMeC is looking to improve the cell effi ciency by using novel lowbandgap
materials and by building multi-junction stacks. the aim
is to develop organic multi-junction devices with effi ciencies over
10%. active layers based on poly-thiophene are deposited by
cost-effi cient techniques such as inkjet printing and spray coating.
and the evaporation of active layers with phthalocyanine
materials is extended to low-vacuum technologies with high
throughput.
single cells are stacked by either thin metallic recombination
layers or by ZnO-based intermediate contacts. Combining layers,
processed from solutions or evaporated, results in complementary
absorption in multi-junction stacks. to reach an operational
lifetime of over 5 years for the solar cells, iMeC is working on
active-layer nanomorphology stabilization and transparent barrier
coatings.
