Today, electronic devices (photodiodes and solar cells) that are running out of efficient life are thrown into the
environment and trigger global warming. In this study, the protective glass surface of a commercial n-Si/p-Si
amorphous solar cell whose photovoltaic parameters decreased over time was coated with nano-sized Ag layer
to gain plasmonic properties. Photovoltaic parameters (JSC = 1.664 mA/cm2
, VOC = 1.567 V, Pmax = 0.465
mW/cm2
, FF = 0.178 and ƞ = 0.5) of the investigated solar cell before the experimental applications were
determined. Then, Ag layers were formed on the glass surface at different substrate temperatures (100-300 K),
and the production regime in which the effective surface plasmon resonance (SPR) event occurred was
determined by optical measurements. FESEM images showed that Ag layer produced at 200 K substrate
temperature was formed by soliton growth mechanism. However, an effective SPR event at a wavelength of
470 nm was observed in the Ag layer coated for 20 seconds. In the next step of the study, the protective glass
surface of the solar cell was covered with Ag at 200 K for 20 seconds, and the solar cell was given plasmonic
properties. The values of photoelectric parameters (JSC = 1.751 mA/cm2
, VOC = 1.599 V, Pmax = 0.550 mW/cm2
,
FF = 0.196 and ƞ = 0.591) in the designed new solar cell were determined and an increase of 18.2% was found
in the efficiency value. The results obtained showed that it is possible to bring photodevices that have
exhausted their useful life back into production with the effect of cryogenic substrate.
