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.
Axpo expands large scale storage business
The Swiss energy group takes on the operation of a 1.25 MW battery storage system owned by Rhiinenergie AG. The storage facility will provide grid balancing services for the country’s grid operator.
Guide to help installers detect hidden costs in high-power modules
Spanish PV product distributor Techno Sun has published a report analyzing the consequences of high-power modules for installers and distributors. The guide provides a method to calculate the additional costs of large solar panels from different points of view.
New photonic material for self-aligning solar cells
US scientists have made light-tracking, three-junction tandem PV cells with an active area of 650 × 650 square micrometers. They are based on indium gallium phosphide, gallium arsenide, and indium gallium arsenide antimony nitride and use photonic crystal film for maximum efficiency.
