Solar costs have fallen 82% since 2010

The levelized cost of energy generated by large scale solar plants is around $0.068/kWh, compared to $0.378 ten years ago and the price fell 13.1% between 2018 and last year alone, according to figures released by the International Renewable Energy Agency.

Harvesting atmospheric water to cool down PV panels

Scientists from Saudi Arabia have proposed a new PV panel cooling technique which employs an atmospheric water harvester. The device uses waste heat from the PV panel to collect atmospheric water at night and then releases it during the day to cool down the module. The researchers claim the device may also be improved to produce liquid water, which could be used for the cleaning of the modules.

Renewables and geopolitics: Who will ‘win’ the energy transition?

The losers in a world which no longer runs on fossil fuels are obvious but the dividend from shrugging off hydrocarbon dependency will be spread around most of the world so it is the nations which are winning the cleantech manufacturing and intellectual property race which appear best positioned for the future.

Lowest shortlisted bid in Saudi 1.47 GW tender was $0.0161/kWh

The shortlisted developers are EDF, Total, ACWA Power, Masdar, First Solar, Marubeni, and Al Blagha Holding.

Could Covid-19 be the catalyst for change where the COP process has stalled?

While the world’s climate negotiators dither, the post Covid-19 world could see their efforts overtaken – but only if policymakers are bold enough to take the opportunity to offer truly green fiscal stimulus packages to get us through the crisis. Felicia Jackson, from the center for sustainable finance of the School of Oriental and African Studies at the University of London, gives her thoughts here.

Saudi Arabia reveals prequalified bidders for 1.2 GW PV tender

The Renewable Energy Project Development Office has prequalified 49 developers for the tender. Four large-scale solar projects will be built via the procurement exercise.

A perovksite-silicon tandem cell with 25.7% efficiency

The device exhibited a small performance loss after a 400-hour thermal stability test at 85 degrees Celsius and after the same period under maximum power point tracking at 40 degrees Celsius, according to its developer. The cell was made by combining solution-processed, micrometer-thick perovskite top cells with fully-textured silicon heterojunction bottom cells.

Egypt evaluating solar desalinators

The government has signed a memorandum of understanding with Saudi energy company ACWA Power to conduct a feasibility study for an unspecified volume of renewables-powered desalination projects.

An inverted perovskite cell with 22.3% efficiency

Saudi researchers have developed a cell which is said to exhibit improved structural and optoelectronic properties as well as enhanced carrier mobility and diffusion lengths. The feat was achieved by reducing voltage losses using a new passivation technique.
