Panasonic testing BIPV glass based on perovskites
Panasonic is now testing perovskite-based power-generating glass with Japanese property developer Mitsui Fudosan Residential at a new building in Kanagawa prefecture, Japan.
New perovskite material for lead-free solar cells
An Algerian research group has analyzed the electronic, elastic, optical, and thermoelectric characteristics of the KGeCl3 perovskite to verify if this lead-free material may be used for solar cells and other electronic devices. The scientists found that the novel material has a direct bandgap semiconductor with bandgap energies of 0.92 eV, 1.26 eV, and 1.88 eV for cubic, tetragonal, and orthorhombic phases, respectively.
IEA-PVPS releases guide for applying innovation system approach to BIPV
IEA-PVPS has published a new handbook that provides support for Technological Innovation System (TIS) analysis for building-integrated photovoltaics (BIPV).
Anda-Olsen unveils lithium iron phosphate batteries
Anda-Olsen launched new LiFePo4 batteries that come with a built-in heating elements that reportedly makes them safe to use even in freezing temperatures. The manufacturer offers the new product in two versions with a nominal capacity of 100 Ah and 200 Ah, respectively.
ClearVue next-gen ‘solar window’ powers through mass production run
Australia’s ClearVue Technologies says it has confirmed the scalability and “commercial viability” of its second-generation integrated glazing units, following a mass production run using a standard manufacturing line at a factory in China.
Prysmian completes world’s longest subsea interconnector
Italy’s Prysmian has finalized the deployment of a high-voltage direct current (HVDC) submarine transmission line spanning 1,400 km, connecting Denmark to the United Kingdom.
Selenium solar cell built with laser-annealing achieves record fill factor of 63.7%
Built by Danish researchers, the device also achieved a power conversion efficiency of 5.0%. They designed the cell with a soda-lime glass substrate, a tin oxide (FTO) layer, an electron transport layer made of titanium oxide (TiO2), a selenium absorber, a molybdenum oxide (MoOx) layer, and a gold (Au) metal contact.
Integrated PVT–air source heat pump for deployment in limited space
South Korean scientists built an air source heat pump integrated with a photovoltaic thermal unit that can reportedly achieve an average heating and cooling coefficient of performance (COP) of 3.54 and 3.31, respectively. The system is also claimed to be 44% cheaper than ground source heat pumps combined with PVT energy.
