In this study, the characteristics of a photovoltaic (PV) ribbon (t = 0.25 mm) joint with 60Sn40Pb and 62Sn2Ag36Pb solders were evaluated using thermal shock tests. The thermal shock tests were performed under three conditions: −40–65 ◦C, −40–85 ◦C, and −40–105 ◦C. The results of these tests were analyzed using electroluminescence (EL) and cross-sectional images. Following testing, broken metal...

We have fabricated poly(3-hexylthiophene) (P3HT)/copper phthalocyanine (CuPc)/fullerene (C60) ternary blend films. This photoactive layer is sandwiched between an indium tin oxide (ITO)/poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT/PSS) photoanode and a bathocuproine (BCP)/aluminium photocathode. The thin films have been characterized by atomic force microscope (AFM) and ultra...

There are many different possible combinations of building envelope, utility equipments and onsite energy generation equipments that can lead to net zero-energy performance. For instance, a building with standard design can offset its energy demand by adding a large amount of photovoltaic cells or by improving its energy efficiency rating first and then adding a smaller amount of photovoltaic c...

Renewable energy has known a great interest during the last two decades. Solar energy is viewed as the cleanest renewable source of energy for the future since it is the least polluting and the most inexhaustible of all known energy sources. Subsequently, technologies that enable the use of solar energy focus on solar thermal collectors and on the photovoltaic effect of semiconductors to genera...

We have recently reported on a small organic molecule containing a bithiophene core with end-capping phthalimide units (PthTh2Pth) that exhibited a H-aggregation tendency in the solid state and high electron mobility in organic field effect transistors. In this contribution, we have studied both the physical and electrical properties of poly(3-hexylthiophene) (P3HT) and PthTh2Pth thin films by ...

Abstract The purpose of this paper is to study how to apply distributed storage into a photovoltaic microgrid for rural villages with electrical network powered by renewable sources and small thermal generators. Using distributed storage helps to reduce Joule losses and voltage drops. This allows reducing the cable’s section or the power source’s size. The main work will focus on optimizing the...

We present a modelling approach to support the layout optimisation of decentralised energy systems composed of photovoltaic (PV) panels and heat pumps with thermal storage capabilities. The approach integrates the simulation-based generation of model input on the basis of publicly available meteorological data and the subsequent optimisation. Selected results concerning the choice of an appropr...
