As the development of organic photovoltaic (OPV) solar cells is expanding, a variety of low band gap polymers (LBGPs) continue to be explored in efforts to improve device efficiency. These polymers, however, require a diverse range of process chemicals for fabrication. In an effort to provide guidance on environmentally responsible polymer selection, chemical hazard assessment was conducted to investigate the toxicity of the associated process chemicals. Specifically, we used the GreenScreen for Safer Chemicals TM framework to evaluate the process chemicals used to make thirteen different LBGPs through select laboratory scale processes. More than 140 distinct chemicals were evaluated. By using GreenScreen, several databases were examined, and the results demonstrate that most of the chemicals are chemicals of high concern due to priority human health toxicities and/or other hazards. The role of data gaps in creating uncertainty and the inability to evaluate some of the chemicals was also investigated.
