Actually PV-technology is the third most important renewable energy source in terms of globally installed capacity after hydro and wind power. In 2012, the European Photovoltaic Industry Association (EPIA) reported the addition of 31.1 GW of new PV capacity, up from 30.4 GW in 2011, which brings the cummulative global solar PV installed capacity above 100 GW. For reference purposes, one power plant reactor produces about 1.3 GW of electricity per year (1 GW = 1 billion watts). Overall, the global deployment of BIPV is small in comparison with of globally installed PV. However, according to a new report from NanoMarkets, BIPV systems worldwide is expected to grow from over 400 MW in 2012 to 2,250 MW in 2017, and the market for building-integrated photovoltaic technology is expected to boom in the next few years, moving from $606 million this year to $2.4 billion. BIPVs are photovoltaic materials that replace conventional building materials in parts of the building envelopes, such as the roof covering or facades and serves as a building envelope material and power generator simultaneously. BIPV systems may represent a powerful and versatile tool for achieving the ever increasing demand for zero energy and zero emission buildings of the near future. In this respect BIPVs offer an aesthetical, economical and technical solution to integrate solar cells harvesting solar radiation to produce electricity within the climate envelopes of buildings. To achieve such goal we believe that architects should work together with R&D scientists to design and successfully integrate solar panels into the building as functional/constructive component replacing the traditional building element. The PV system must of course meet the criteria of efficiency in energy production, particularly with regard to positioning and orientation of the modules and the absence of shading. In this talk we, summarizes the current state-of-the-art of PV technology with particular interest to thin films and BIPV. Secondly, we discuss a possible future research opportunities and pathways for the BIPVs to be integrated in both new and existing buildings in Morocco. The following thin films technologies can be developed with reduced production costs and improved building integration. – Wafer silicon technology – Flexible lightweight inorganic thin film solar cells in roll-to-Roll – See-through thin-film PV products, semi-transparent characteristic that provide wonderful visual comfort. – New concept that use less material (Extremely Thin Absorber or ETA) – Dye sensitized (DSSC) and Perovskite solar cells – Organic polymer technology
