title: The photovoltaic industry on the path to a sustainable future--environmental and occupational health issues.
abstract: As it supplies solar power, a priori considered harmless for the environment and human health compared with fossil fuels, the photovoltaic (PV) industry seems to contribute optimally to reduce greenhouse gas emissions and, overall, to sustainable development. However, considering the forecast for rapid growth, its use of potentially toxic substances and manufacturing processes presenting health and safety problems may jeopardize its benefits. This paper aims to establish a profile of the PV industry in order to determine current and emerging environmental and health concerns. A review of PV system life cycle assessments, in light of the current state of the industry and its developmental prospects, reveals information deficits concerning some sensitive life cycle indicators and environmental impacts, together with incomplete information on toxicological data and studies of workers' exposure to different chemical and physical hazards. Although solar panel installation is generally considered relatively safe, the occupational health concerns related to the growing number of hazardous materials handled in the PV industry warrants an all-inclusive occupational health and safety approach in order to achieve an optimal equilibrium with sustainability. To prevent eco-health problems from offsetting the benefits currently offered by the PV industry, manufacturers should cooperate actively with workers, researchers and government agencies toward improved and more transparent research, the adoption of specific and stricter regulations, the implementation of preventive risk management of occupational health and safety and, lastly, greater responsibilization toward PV systems from their design until their end of life.
