Among the manifold ways to generate electricity from renewable sources, solar PV modules are believed to be one of the most efficient. Especially heterojunction solar cells have a low carbon footprint because of the sparing use of silicon in them and high efficiency levels in industrial production. During the production of heterojunction cells the element silver is used for busbars and contacts. Silver conducts the electricity that is...

The sun is an abundant source of energy. The sunlight which hits the earth in the course of a day is enough to cover the world’s energy consumption for a very long time. This energy can be harnessed using photovoltaic (PV) panels or through mirrors that concentrate solar radiation and used to generate electricity or be stored in batteries or thermal storage. Solar panels, also known as photovoltaics, are made up of semiconductor...

Presently, the global market for floating solar panels is estimated to be a few dozens of millions of US dollars. At the same time, only 10-15% of floating stations are equipped with active solar tracking systems. Nevertheless, many experts expect a significant growth in this segment of market in the next decade, predominantly in the countries of Southeast Asia. Therefore, the largest suppliers of floating panels are Japanese Kyocera...

Halide perovskites are generally regarded as materials which have high performance potential while reducing production costs. The name is derived from the mineral calcium titanium oxide CaTiO 3 (XIIA2+VIB4+X2−3) and is also used for the class of compounds which have the same crystal structure, called the perovskite structure. Perovskite solar cells have witnessed a rapid development in recent years, with efficiencies increasing to over...

The idea to use sunlight for energy production is not new. The first modern solar cell was invented in 1954 at Bell Laboratories, an American industrial research and scientific development company now owned by Finnish company Nokia. Sunrays hitting the surface of a photovoltaic (PV) cell can be reflected, absorbed or pass through the solar cell. This is enabled by the semiconductor material of which the cell is composed. Semiconductors...

One of the options to substantially increase the efficiency of solar technologies is the implementation of trackers, devices that follow the solar position and correspondingly orient photovoltaic panels or mirror reflectors. There is a multi-level classification of trackers based on their functional capabilities. First of all, passive and active trackers can be distinguished. In the latter case special actuating mechanisms such as...

Energy storage technologies constitute one of the most important domains of the modern energy industry. The key problem holding back the development of renewable energy is the variability in operation of solar and wind power plants due to the natural characteristics of these resources. The development and improvement of high-capacity energy storage technology largely determines the further development and competitiveness of these...
