摘要：
The power conversion efficiency of organic solar (OSCs) has increased from around 1% to over 10% in the past two decades. In spite of the great success in device efficiency, many fundamental issues concerning basic operational mechanisms of these devices remain unknown or controversial, limiting rational design of donor and acceptor materials. Among others, charge generation might the most fundamental yet most debated issue. We employ straightforward temperature-dependent open-circuit voltage measurements to understand the effect of temperature on charge generation. We also employ highly sensitive charge-transfer state measurements to understand the effect of additives on energetic disorder (and hence charge generation) of OSCs.
