Abstract
The use of photovoltaic technology is crucial to meet Europe´s ambitious climate and energy objectives set for 2030. To facilitate this shift, technological innovation is a key prerequisite, and the provision of public funding for related research and development is an important trigger. For this study, a vast set of data has been collected to explore how the EU and itsMember States, plus Norway and Turkey, have so far invested in photovoltaic research and development. Based on historic values and actual trends, the authors additionally outline the possible future evolution of the investigated public funding. The study aims to shed light on the development of funding from the early 1970s until 2017 (most recent data available) and provide a forecast for 2030 (based on a business-as-usual scenario). According to results, at the national level, public funding had a considerable and steady rise after the OPEC´s oil embargo in 1973, reaching a first peak in the mid-1980s. The authors predict that, according to the most recent trends, by 2030, these will surpass 200 million e annually. In comparison, EU funding has steadily increased since its inception in the late 1980s up until 2007, but its evolvement is distinctively different, evidencing high fluctuations. The cumulative stock is also examined. National sources outweigh EU programs by a factor of almost five, and the stock should surpass 7 billion e by 2030. Based on the analysis and related insights, recommendations are elaborated on how the development of funding could inform policy strategies and actions to support research and development for photovoltaic technology.
