Table 1 HOMO and LUMO levels of PCBM changed by electron irradiation as a function of electron fluence

From: Tuning the electronic band structure of PCBM by electron irradiation

	E_{p, red(1)}	E _{on, red (1)}	LUMO	E _{p, ox}	E _{on, ox}	HOMO
PCBM	-1.11	-0.98	-3.70	1.76	1.50	-6.18
PCBM (3.6 × 10¹⁶ cm^-2)	-1.22	-1.09	-3.59	1.79	1.55	-6.23
PCBM (7.2 × 10¹⁶ cm^-2)	-1.41	-1.18	-3.50	1.86	1.56	-6.24
PCBM (1.44 × 10¹⁷ cm^-2)	-1.49	-1.28	-3.40	1.94	1.57	-6.25

The first reduction and oxidation peak potentials (voltage vs. Ag/Ag⁺), onset potentials, and LUMO and HOMO level (electron volts) of electron-irradiated PCBM at different fluences.
