Water-splitting tech to reduce moisture in perovskite solar cells
Italian researchers have engineered a hole extraction layer with water-splitting additives to reduce the impact of moisture in perovskite PV devices. They claim that the method ensured a power conversion efficiency of more than 9% in perovskite cells stored for a month in a water-saturated atmosphere.
Chinese PV Industry Brief: Huge orders for Trina Solar and JYT Corporation
Trina Solar has secured a 4 GW solar module order from US company Nextera Energy and wafer manufacturer JYT Corporation closed deals to supply a total of 1,906,000,000 wafers.
JinkoSolar claims 24.9% efficiency for n-type monocrystalline cell
The result was confirmed by Germany’s Institute for Solar Energy Research (ISFH).
Semitransparent bifacial CIGS cell with 10.5% efficiency
The solar cell was developed by Korean scientists for power-generating window applications. They built the device with transparent conducting oxide (TCO) rear contacts and a textured polydimethylsiloxane (PDMS) layer with light-scattering and antireflection properties.
Chinese PV Industry Brief: more manufacturing capacity from Trina, GCL Integration and Eging PV
Plans to set up new cell and module capacities have been announced by the three manufacturers. Trina intends to add 10 GW of cell capacity to its manufacturing site in the Sichuan province, while GCL Integration wants to build an 8.5 GW monocrystalline solar cell factory in the Jiangsu province.
Stanford scientists gain insight on polaron distortion in perovskite solar cells
Polaron formation in perovskite solar cells has been indicated in scientific research as a possible factor for making this kind of cell particularly efficient, although the mechanism behind polarons’ action is completely unknown. A U.S. research group has now observed how polaron distortions form and grow.
Kazatomprom again seeks to sell solar manufacturing units
The Kazakh state-owned national atomic energy company is seeking to sell its solar manufacturing units for the second time.
Artificial intelligence in photovoltaic production
Five scientific institutions in Germany are currently working together on self-learning production plants that use process data for the permanent optimization of manufacturing. The initiative is aimed at making the settlement of photovoltaic factories in Germany and Europe attractive again.
Thermal model to predict PV panel temperature
Scientists in Turkey have tested a transient thermal model to predict PV module temperature during a five-day interval in June. The model considers the heat capacity of a PV module, which is usually not provided by manufacturers in their product sheets, as a parameter for temperature prediction.
Australian research improves scope, efficiency of PV light sensitizers
Australian scientists have developed an algorithm to increase both the efficiency and compatibility of light sensitizers in solar panels.
