N-doping of perovskite solar cell: Technology that increases the power conversion efficiency of solar cells
Domaine Energie
Technologie Solaire / Photovoltaïque
CHALLENGES
- A very competitive chinese market
- An electronical doping of perovskite
- A yield losses from materials conception
INNOVATIVE SOLUTION
The technology involves a two-step spin coating process for n-doping methylammonium lead iodide (MAPI) perovskite solar cells. This controlled doping method enhances the electrical properties, increasing efficiency and reducing contact resistance in the solar cells
Applications
This invention can be applied to solar cell, but also enables the design of all basic electronic components (PN junctions, transistors, etc.).
Advantages
-
Increase of Power Conversion Efficiency
-
Decrease of contact resistance (Rseries (Ω))
-
Increase of open circuit voltage
DEVELOPMENT STATUS : TRL 3
- Proof of concept
