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.
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.
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.
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.
Can you design sustainable PV backsheets without compromising performance?
While the quality of materials and components has thus far been a particular focus for manufacturers looking to offer premium products that stand the test of time, sustainability is increasingly on the agenda as end-of-life waste mounts, and customer and policy demands change. A growing number of manufacturers recognize the benefits of integrating sustainable design and production principles, like lower long-term costs, due to material reuse, for example, without compromising on other aspects.
Chinese PV Industry Brief: Another factory under construction
Talesun has begun work on its 5 GW factory in Siyang county, Jiangsu province and China’s second-largest grid operator, China Southern Power Grid, has announced around 200 GW of renewable energy capacity will be deployed on its service area over the next 10 years.
Spanish solar renaissance lifts world to record year for large scale projects
A global ranking of large scale solar project capacities indicates prominent roles for a resurgent Spain, behind the usual top three of China, the U.S. and India, with Australia and the Netherlands also on the rise. There were disappointing returns, though, for the U.K., Italy and Canada.
Indian state of Uttar Pradesh tenders 75 MW grid-connected solar capacity
Global bids are invited to develop an aggregate 75 MW of grid-connected solar power projects with an upper tariff ceiling fixed at INR 3.00/kWh ($0.041/kWh) for the entire power purchase duration of 25 years. The projects are to be installed in the Uttar Pradesh Solar Park on a build-own-operate basis.
Chinese utility pitches energy transformation credentials
The fossil fuel assets belonging to the state-owned parent of China Power International Development might overshadow the latter’s green claims but the Hong Kong-listed utility said it reached full operation at 940 MW of solar farms in 2020–more than half of it unsubsidized.
Indonesian government has vastly underestimated solar potential
A Jakarta thinktank says the authorities need to significantly raise their clean energy ambitions as even the most conservative estimates of the volume of solar capacity the nation could host far outstrip the 207 GW the energy ministry has suggested.
