Study, characterization and comparison of photovoltaic devices both for indoor and outdoor application

We compared two different types of PV devices, such as silicon and dye-sensitized solar cells, for harvesting in two different light condition (indoor and outdoor). With the aim to develop low-cost, stable, and efficient PV cells for indoor/outdoor applications, extensive investigation is necessary to resolve some critical issues concerning PV cells, such as large area fabrication, environmental stability, mechanical flexibility, lifetime and fabrication cost. In addition biocompatibility of these devices should be improved through the development of new, non-toxic materials.
