Perovskite solar cell achieves 24.3% efficiency, high stability via binary mixed hole transport layer
Researchers in China have built a hole transport layer with a mixed binary configuration integrating the polymer Regioregular poly(3-hexylthiophene) (P3HT) and Spiro-OMeTAD. They used it to build a perovskite solar cell that was able to retain 90% of its initial efficiency after 1,200 hours of storage in dark ambient environment.

LG unveils US residential energy storage system
LG has developed a new energy storage system for the US residential market that combines two 10-hour batteries or 16-hour Prime battery modules in parallel, providing 19.2 kWh to 32 kWh of capacity and a maximum 9.6 kW output from the inverter.
Potential locations for solar, wind hybrid projects in India
Indian scientists have created a hybrid power exploitability index to identify optimal locations for constructing new solar and wind hybrid power plants. They have evaluated retrofitting existing standalone plants and have discovered that all but one of the eight plants could be hybridized, with up to a 400% annual increase in power output.
Mobile application to predict optimal energy efficient route for solar vehicles
Irish researchers have created a mobile app that calculates the best route for solar-powered vehicles based on user preferences for time and energy efficiency. The app’s experiment predicted the most energy-absorbing route with 51.65% accuracy and chose the most energy-consuming route with 86.65% accuracy.
Low-cost, portable sun-tracker for offgrid solar
Mauritian researchers have developed a solar tracker prototype that increases current by around 37%. The device uses a simplified and mechanical tracking system.
Weekend Read: New turf for thin films
Thin-film technologies have long promised to make a major impact on the solar industry but have largely been constrained to niche applications and research labs if they were not shredded by the market. After several false starts, current trade dynamics and promising research programs may help solar thin films find their place in the sun.
