When you talk to the pioneers of the German PV industry, such as Mr. Udo Möhrstedt or the first participants of the symposium at Banz Monastery, one looks back at the early years with a sparkle in the eyes. A specific example is the comparison between the wafer sizes of the past and the present. The “wafer” is the starting material for the production of crystalline solar cells, which is only about 200 µm thick. Although there have been many adjustments over the years, the continuity has unfortunately disappeared. In recent months, countless new wafer sizes have appeared on the market. Something the PV industry has never experienced before. In addition, there is no uniform designation. With this article we would like to shed some light on the topic, and in addition to a review of the history of cell size, we want to compare the current common names. (more…)
The photovoltaic market has increased significantly over the last decade. In 2015, the annual PV installation was over 50 GW and the solar cells made with Multi Crystalline Silicon (mc-Si) had a market share of nearly 60 %. This year, however, the majority of European countries noticed a significant switch to Mono Crystalline Silicon with ratios of ~70 % in comparison to 30 % mc-Si. Regardless of the technology, one aspect is absolutely clear: the market is still going the direction where customers worldwide require higher efficiencies. The prices, however, have to stabilise or should get lower. By fulling this demand, cell and solar module producers are required to provide a solution to offer higher efficiencies at the same or lower level of prizing. In Sep 2018 we introduced you to our new module technologies which includes Half Cell, Multi Busbar or optimized cell connector like LRF. This time we want to take a closer look the Cast Mono technology. This is used for one of our new IBC solar modules, the IBC MonoSol xxx RS-HCC. (more…)
A walk through our test facility allows you to immerse yourself in the history of photovoltaics. Many previous generation modules , some already now a decade and a half old, show how technology has advanced. In our blog series, guest author and product manager René Schüler presents special test objects and reports in our latest contribution together with Manuel Baier about the latest system at our facility. In addition to the previous crystalline poly- and mono- solar modules, so-called bifacial modules have now also been inspected at the open-space test facility. (more…)
In the course of climate change and developments in traffic, e-mobility is nowadays widely discussed. The fact is: e-cars emit less CO2 than conventional vehicles and can also serve as energy storage to compensate for fluctuations in renewable energies. This way e-cars can make a big contribution to the energy transition. It is no wonder that the number of electric vehicles is increasing. And this not only applies to the private sector. Also in the public sector buses with electric drive are being increasingly used. The latest example is provided by our partner BYD, which will supply the Ruhr area with a total of 22 fully electric e-buses in summer 2020.
“We’ve come to make solar energy an important renewable and local energy source.” This is what IBC SOLAR AB, based in Stockholm, Sweden, who recently launched this year believes. They are the first franchisee of IBC SOLAR and supply smaller installation companies with components for solar systems in the residential and small commercial rooftop segment.(more…)
