A profound understanding of the ultrafast interfacial charge transfer (CT), charge separation (CS), and charge recombination (CR) are paramount in enhancing the photoconversion efficiency (PCE) of the solar cell devices. Here, a combination of steady-state and femtosecond transient absorption spectroscopies with broadband capabilities are used to explore and decipher the photoinduced charge carrier dynamics at the PCE10/C60 interfaces. Our experimental results verified the efficient and ultrafast (sub-picosecond) photoinduced electron transfer (ET) from the PCE10 polymer to fullerene acceptor C60. Notably, the slow CR and fast ET make the current PCE10/C60 system ideal for its potential use in solar cells devices.
