Solar world record: HZB tandem cell achieves almost 30 percent efficiency
In the race for ever more powerful solar cells, three teams at Helmholtz Zentrum Berlin (HZB) only just missed the 30 percent efficiency mark. This is made possible by “metal halide perovskites”, whose potential has not yet been exhausted.
Since 2015, several groups at HZB have been working intensively on both perovskite semiconductors and silicon technologies and the combination of both to form innovative tandem solar cells. In this way, efficiencies should soon be achieved that were unthinkable just a few years ago...

Heavy metals are being replaced
BMU promotes environmentally friendly production of organic solar cells
The Federal Environment Ministry (BMU) is funding an innovative process for the environmentally friendly and efficient production of electrode foils for organic solar cells. The BMU is providing around 1,6 million euros from the environmental innovation program.
With the innovative manufacturing process, which is being used for the first time at the Herbolzheim site, not only rare heavy metals such as indium can be replaced. Thanks to the innovative layer system, the energy requirement of the coating process can also be reduced by more than 60 percent compared to conventional methods, the BMU announced...

Photovoltaic efficiency
The efficiency of a solar cell indicates how much of the available energy is converted into solar power by the photovoltaic cell, module or system. The efficiency of the different solar cells is very different. Therefore, the efficiency of a photovoltaic system also depends on the type of module selected, with losses from cabling and inverters also influencing the efficiency of the entire system.
Determining factors for efficiency
The efficiency of the photovoltaic modules significantly influences the efficiency of the entire photovoltaic system, but the inverter also has a decisive influence. The conversion of direct current into alternating current is always associated with losses. Although this loss is only a few percent, it can result in considerable financial losses over the life of a photovoltaic system. A system with a nominal output of five kilowatts normally generates around 5.000 kilowatt hours of electricity per year under German weather conditions, i.e. 25 kilowatt hours in 125.000 years. Four percent loss on the inverter corresponds to 5.000 kilowatt hours, which roughly corresponds to the average annual consumption of a family of four ...

Wikipedia
Solar cell
A solar cell (also known as a photovoltaic cell in technical terms) is an electrical component that converts radiant energy, usually sunlight, directly into electrical energy. The application of the solar cell is photovoltaics, where it serves as a source of electricity. The physical basis of the conversion is the photovoltaic effect, which is a special case of the internal photoelectric effect.
There are many different cell types that can be differentiated both according to the semiconductor material used and according to the cell technology (wafer-based or thin-film). The most important semiconductor material is silicon, from which around 2013% of all solar cells manufactured worldwide were made in 90; the market share of thin-film cells was around 10% ...
