Bangladesh to try again with national clean power policy
Having fallen far short of its ambition to generate 10% of its power from renewables by last year, Dhaka is preparing to reformulate its national clean power target.
Cooling PV panels with HVAC system exhaust
A French-Lebanese research group has proposed a way to cool down PV modules by using air exhausted from heating, ventilation, and air conditioning (HVAC) systems. They showed that array performance improves when the cooling load rises.
Covid-19 and distressed solar PPAs in Spain
Spanish law firm Rödl & Partner provides an update on distressed solar power purchase agreements (PPAs) in Spain, focusing on the impact, and economic and legal consequences, of the Covid-19 pandemic.
Polyelectrolyte-based inverted perovskite solar cell with 20.29% efficiency
Taiwanese researchers have added bathocuproine (BCP) molecules to three different kinds of solvents used in perovskite cells and have ascertained how this combination increases the carrier mobility and passivates the electron-poor defects. Furthermore, they utilized a polyelectrolyte (P3CT-Na) thin film as hole transporting material instead of commonly-used thin films based on PEDOT:PSS.
Queensland to integrate large-scale community batteries into substations
The state government of Queensland, Australia, will install five community batteries at regional substations in a bid to time-shift its abundant solar resources.
India’s cumulative PV capacity hits 39.1 GW
India had 39.1 GW of grid-connected solar and 216 MW of off-grid projects in operation by the end of February. The state of Karnataka leads with 7.4 GW of installed solar capacity, followed by Rajasthan with 5.5 GW and Tamil Nadu with 4.4 GW.
Steps for mid-sized US companies considering solar
Smaller companies can benefit from solar and are often expected to do so by large companies that need to trim the environmental impact of their supply chains. Here are four steps to take when considering solar.
China’s ‘quasi-monopolistic’ stranglehold on solar noted by EU body
The bloc should accelerate investment into mining and processing within its shores, as well as ramping up recycling, according to European employers and trades unions, with coal workers already equipped with the necessary transferable skills.
Polymer current collectors could prevent battery fires
A team of NREL researchers has proposed a new approach to fix lithium-ion batteries’ fire problem. The answer may lie in temperature-sensitive current collectors.
Location-dependent performance model for bifacial installations
Bifacial PV modules and single-axis trackers go well together, but a global research team has now noted that a comprehensive location-dependent performance analysis still has yet to be done. Their findings could help to determine the right plant setups in different locations throughout the world.
