Monolithic perovskite-PERC tandem solar cell with 23.7% efficiency
Dutch scientists have developed a perovskite-PERC tandem solar cell based on a new type of tunnel recombination junction that reportedly offers an improved device efficiency distribution. The cell uses a nickel(II) oxide layer that is intended to reduce electrical shunts in the perovskite top cell.
Navitas Solar sets up US manufacturing unit
Indian manufacturer Navitas Solar has collaborated with US-based Sustainable Equity and Colby Solar to set up a module factory with a manufacturing capacity of 1.2 GW per annum.
Fraunhofer ISE integrates solar cells into car hood
Germany’s Fraunhofer Institute for Solar Energy (ISE) has advanced vehicle-integrated PV (VIPV) technology by installing solar cells directly onto a standard sheet-metal car hood. The researchers placed a 115 W prototype array on the hood of a Volkswagen with a specialized lamination process.
Perovskite solar cell built on steel substrate achieves record efficiency of 17.1%
Scientists in Australia claim to have achieved the highest efficiency ever reported to date for a perovskite solar cell built on a steel substrate. They utilized an indium tin oxide (ITO) interlayer between the steel substrate and the cell in order to avoid iron diffusion from the substrate into the PV device.
Saudi researchers apply distributionally robust optimization to wind, solar project siting
Saudi scientists created a new deep learning technique based on distributionally robust optimization (DRO) to identify the most suitable locations for utility scale wind and solar power projects. They applied the model to Saudi Arabia and found it provides ‘more realistic’ results than deterministic or robust models.
Sekisui Chemical unveils plan to produce solar thin films based on perovskite
A spokesperson from the Japanese plastics maker told pv magazine that production is currently being carried out at a small facility in the laboratory, and that the location of a full-scale production facility is currently under consideration.
German consortium plans 5 GW vertically integrated solar module production
Heckert Solar, Wattkraft and Interfloat are planning to invest around €2 billion ($2.18 billion) in three different manufacturing facilities that will produce everything from polysilicon to solar modules.
All-inorganic phase heterojunction perovskite solar cell with 21.59% efficiency
An international research team has developed high-efficiency solar cells with a 21.59% efficiency rating by using an all-inorganic phase heterojunction approach. The team used an anti-solvent-free DHA method to produce high-quality, inorganic perovskite thin films, resulting in better device performance under ambient conditions.
ClearVue releases results from first long-term study of clear solar glass
Perth-based ClearVue is making significant strides as its transparent solar windows demonstrate tangible outcomes following a two-year study and published paper.
China wafer prices extend gains for third week
In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.
