Abstract EN
Nanoparticle (NP) arrays of noble metals strongly absorb light in the visible to infrared wavelengths through resonant interactions between the incident electromagnetic field and the metal’s free electron plasma.
Such plasmonic interfaces enhance light absorption and photocurrent in solar cells.
We report a cost-effective and scalable room temperature/pressure spin-coating route to fabricate broadband plasmonic interfaces consisting of silver NPs.
The NP interface yields photocurrent enhancement (PE) in thin film silicon devices by up to 200% which is significantly greater than previously reported values.
For coatings produced from Ag nanoink containing particles with average diameter of 40 nm, an optimal NP surface coverage ϕ of 7% is observed.
Scanning electron microscopy of interface morphologies revealed that for low ϕ , particles are well separated, resulting in broadband PE.
At higher ϕ , formation of particle strings and clusters causes red-shifting of the PE peak and a narrower spectral response.
