Improving Performance of InGaN/GaN Light-Emitting Diodes and GaAs Solar Cells Using Luminescent Gold Nanoclusters

Table 1

Photovoltaic I-V results of the GaAs single-junction solar cells without and with incorporation of the luminescent Au nanoclusters. 𝑉_OC is the open-circuit voltage, 𝐼_𝐒𝐂 is the short-circuit current, 𝐹𝐹 is fill factor , and 𝜂 is conversion efficiency.

Sample	𝑉oc (V)	𝐼sc (mA)	𝐹𝐹	𝜂 (%)
Untreated	0.99	5.72	0.73	16.2
With Au nanoclusters	0.99	6.52	0.74	18.7
