The main goal for this report is to alert for the need of a continuous investment in policies that should be developed worldwide, with respect to research and development (R&D), at all levels, in photovoltaic energy. The R&D in this area leads to a strong and possible solution to the actual environmental problems. Such problems are based on the climate change due to polluted gas emissions and due to the non-renewable resources exhaustion. Therefore, this contribution for a roadmap of photovoltaic technology aims to support the knowledge on projects that allow photovoltaic module cost reduction, efficiency and longevity improvement. In this paper we analyze the implemented policies and projects that were and are being developed worldwide. A development monitoring is done in photovoltaic energy since its origin, in order to predict its evolution in actual market. The data was analyzed and the conclusion was drawn that the solar energetic consumption evolution is related to the efficiency improvement and cost reduction in photovoltaic technologies, mainly due to the rising competitiveness among other sources of energy. The non-dependency on non-renewable and pollutant resources implies a significant rising of hope for a better future.
