Quantum dots boost perovskite solar cell efficiency and scalability

Posted by in categories: quantum physics, solar power, sustainability

Perovskites are hybrid compounds made from metal halides and organic constituents. They show great potential in a range of applications, e.g. LED lights, lasers, and photodetectors, but their major contribution is in solar cells, where they are poised to overtake the market from their silicon counterparts.

One of the obstacles facing the commercialization of solar is that their power-conversion efficiency and operational stability drop as they scale up, making it a challenge to maintain in a complete solar cell.

The problem is partly with the cell’s electron-transport , which ensures that the electrons produced when the cell absorbs light will transfer efficiently to the device’s electrode. In perovskite solar cells, the electron-transport layer is made with mesoporous titanium dioxide, which shows low electron mobility, and is also susceptible to adverse, photocatalytic events under ultraviolet light.

100% Zero-Emissions Cherry Orchard

Posted by in categories: climatology, solar power, sustainability

Forest Lodge Orchard is New Zealand’s first zero-emissions food producer. Forest Lodge Orchard is located in Central Otago, New Zealand, and is 100% free of fossil fuels. The farmers have electrified everything at the orchard — their irrigation, frost-fighting fans, electric vehicles, tools, and more. Supporting this electrification with a 45 kW solar power array and extendable battery storage system.

In January 2022, Forest Lodge will have its first zero-emission harvest of cherries. The focus is on the climate, and the folks at Forest Lodge believe that New Zealand’s future as a food-producing nation will excel with the ability to grow and produce food in a sustainable and climate-friendly way.

California has more rooftops with solar panels than any other state and continues to be a leader in new installations. It is also first in terms of the percentage of the state’s electricity coming from solar, and third for solar power capacity per capita. However, former California governor Arnold Schwarzenegger has expressed concerns that California.

Is The California Solar Dream Fading Fast?

Posted by in categories: solar power, sustainability

California has more rooftops with solar panels than any other state and continues to be a leader in new installations. It is also first in terms of the percentage of the state’s electricity coming from solar, and third for solar power capacity per capita. However, former California governor Arnold Schwarzenegger has expressed concerns that California solar — once the model for other US states — is on a precipice. In an opinion piece for the New York Times this week, Schwarzenegger has unpacked a new California Public Utilities Commission proposal which, if approved, would discourage progress being made in the transition to clean energy and grid resilience.

What’s the problem, then? The California Public Utilities Commission is threatening solar progress. But this “hard-earned and vitally important accomplishment” may succumb as the Commission considers a plan that has the potential to make California solar too costly for its citizens.

EWZ builds another solar plant on a dam wall in the Alps

Posted by in categories: solar power, sustainability

The Elektrizitätswerk Zürich (EWZ) sees the construction of solar plants in the high alpine regions of Switzerland as a secure mainstay. The utility is planning another solar plant on the dam wall of a hydroelectric power plant high up in the mountains. The company plans to install more than 1,000 solar modules with an output of 350 kilowatts on the 690-metre-long dam wall of Lago di Lei in Graubünden. The system will cover the dam wall over a length of 550 metres and, once completed, will supply around 380 megawatt hours of electricity each year.

This is already the second installation of this kind to be completed by the EWZ. The first is at the dam of Lake Albigna, also in the canton of Graubünden. This plant has been in operation for a year and has fully met the expectations of the EWZ, so that the forecasts for the new plant are also good. As there, the electricity at Lago di Lei, directly on the border with Italy, will also be fed in via the grid connection of the associated hydroelectric plant of the Hinterrhein power station (KHR). “This makes optimal use of the existing infrastructure to make a further contribution to electricity production from solar energy,” emphasises Guido Conrad, director of the CHR.

Solar power excels in Turkey’s rapid shift to green energy sources

Posted by in categories: solar power, sustainability

See, when there is no hypocrisy of being an oil tycoon nation, talking to much in conferences about environmental incentives whilst having a double agenda which consists of slowing the trend down, or doing nothing while we get to 2030.

IT ACTUALLY WORKS


Turkey’s rapid shift to greener sources of energy has led to a sharp rise in its installed solar power over the last decade, with renewable investments expected to accelerate in the period ahead.

These solar panels are thinner than a piece of paper

Posted by in categories: solar power, sustainability

That reality might not be too far off.

“This would enable the integration of solar cells into everything.”

Stanford University researchers announced they had achieved record efficiencies in a promising class of new materials for solar cells — which can be thinner than a piece of paper.
