Italian government streamlines another 593 MW of agrivoltaics
The Italian cabinet has approved 13 agrivoltaic projects in the southern regions of Apulia and Basilicata.
Germany’s PV systems inject 40 GW of PV into grid for first time
In the first week of May, the photovoltaic systems installed in Germany made the largest contribution to net electricity generation. They fed a total of 1,744.46 GWh of solar power into the grid and thus had a share of 23.6%.
Novel thermoacoustic heat pump system for residential applications
Developed by Chinese researchers, the system is designed to reach a heating capacity of 5.7 kW and an overall coefficient of performance of 1.40 at nominal conditions. It is made with an engine unit, a heat pump unit, and a gas resonator unit in a loop.
The PV scientific community’s rush to the latest efficiency record
Perovskite-silicon tandem technology expert Gianluca Coletti explains what cycles the PV industry and scientific community experience every time there are new jumps in power conversion efficiencies at cell level. According to him, we are experiencing a much faster turnover of efficiency records typical of the early stage of development of a new technology holding an incredible potential.
Botswana set to host 30 MW of solar with LCOE of $0.08-0.10/kWh
Pash Global and Tswana Renewables have formed a joint venture to develop small-scale PV plants across Botswana. For the first two 400 kW projects they have already secured a power purchase agreement.
A closer look at Longi’s world record-breaking, 26.81%-efficient heterojunction solar cell
An international research group led by Longi Central R&D Institute has published a paper describing Longi’s heterojunction solar cell based on a full-size silicon wafer that made a sensation in November, as it beat the long-lasting efficiency record held by Japanese manufacturer Kaneka for years. The researchers attributed the cell efficiency improvement to the implementation of a p-type amorphous silicon hydrogenated layer together with a modified transparent conductive oxides contact, which they said greatly reduced the cell contact resistivity.
EU researchers propose new method to calculate carbon footprint of PV modules
Researchers associated with the European Commission have developed a new methodology to calculate the carbon footprint of PV modules for use in the context of the European Union’s ecodesign regulations.
India awards 1 GW of solar at $0.032/kWh
Rajasthan Urja Vikas Nigam Ltd (RUVNL) has allocated 1 GW of solar capacity in its latest auction. The selected developers secured a 25-year power purchase agreement (PPA).
Floating concentrating photovoltaic thermal system for carbon capture
Two Norwegian companies are designing floating concentrating photovoltaic thermal technology that can produce both electricity and heat. It is intended for use in carbon capture projects and to be supported by an industrial heat pump system.
