graphene improves perovskite solar cells

Graphene is used to create a more durable, efficient — and super cheap — Perovskite solar cell. It will still take a while but the new development does keep the promise of perovskites alive.

Graphene is an atom-thin layer of graphite that has unique and powerful electrical properties. Perovskite refers to any synthetic version of the naturally occurring mineral perovskite, which has amazing solar conversion potential. Read More

Perovskite Solar Cell Record 23.9% Efficiency

perovskite breakthrough

Perovskite breakthrough may fast-track new solar PV technology

The Belgium IMEC research center developed a new Perovskite solar cell with a conversion efficiency of 23.9%.

According to IMEC this is even more than the conventional silicon solar cells.

This new step is promissing. Even without Perovskites, the cost of solar power is already competitive with fossil fuels in some markets.

If and when this new innovation breaks through commercially, costs will drop even further.

Promising 2D Perovskite photovoltaics

Promising 2D Perovskite photovoltaics

These results address a long-standing problem not just for the perovskite family, but relevant to a large group of materials

The 2D Perovskite Solar Cell exceeds expectations for solar cell efficiency.

A 2D, layered form of the crystalline material perovskite has become the focus of much excitement in the solar cell research field at the Los Alamos National Laboratory (USA).

New solar cell 1 micrometer thick

New solar cell 1 micrometer thick

By transfer printing instead of etching, the new method developed by Lee and his colleagues may be used to make very flexible photovoltaics with a smaller amount of materials.
The thin cells can be integrated onto glasses frames or fabric and might power the next wave of wearable electronics.

Scientists have developed solar cells of 1 micrometer thick. That’s 100 times thinner than a human hair. Interesting isn’t it?

If we’re ever going to unlock the true potential of solar, we need to think beyond today’s large rooftop solar panels, and examine what smaller, lightweight, and even wearable solar cells could do for us. Read More

PowerWindow saves up to 50%

PowerWindow generates energy

PowerWindows work in direct and indirect light; under any angle towards the sun

The PowerWindow is a fully transparent and colorless electricity-generating window.

Imagine: You are looking out of your window knowing that the same window is recharging your electric car in the garage at the same time. How perfect should that be? 

It’s already possible.

Double-sided PV

Floating double-sided pv

The solar cells at the second side are are almost as efficient as the cells in the front end. As a result, the panels can also utilize the light that is reflected by the surface of the water or the ground, which normally is lost.

By applying double-sided panels – working on water – the yield of solar power can be increased by 20% on average and expand the potential to generate solar energy even more.

So why not use both sides?

Double-sided solar panel

This week, Energy Research Centre (ECN) is demonstrating ‘floating double-sided solar panels on the ‘River IJ’ in Amsterdam. By also using the back of the solar panels, the reflected light from the surface of the water, can be catched to generate electric power. Read More

All-weather PV

all-weather pv

The double layer provides electrical power and provides a voltage, similar to how a battery works.

Clumsy, that solar panels do not generate energy while its raining. Chinese scientists have just figured out that solar panels even generate electricity for all-weather: even when it is raining.

Rainy weather

Solar modules are most effective when they are exposed to direct sunlight, but what happens when it rains? Read More

MiLiCiA – IBC solar cells

MILICIA IBC solar cell

MILICIA IBC solar cell performance do have no shading loss and no trade-off between series resistance and reflectance

Aim of the new MiLiCiA research project is to develop a low-concentration PV technology that can compete with conventional power generation without subsidies or feed-in tariffs. Read More

MIT Ultrathin Solar Cell

MIT Ultrathin Solar Cell

The solar cell generates a lot of energy per weight: about 6 watts per gram which is about 400 times more than an average silicone solar cell.

MIT Researchers have developed a very thin, lightweight and flexible solar cell.

In the future, the technology allows solar cells to be used for caps, smart phones, paper and even a helium balloon. Read More

Transparant Solar Cells

Transparant Solar Cells

The solar harvesting system uses small organic molecules developed by Richard Lunt of MSU’s College of Engineering and his team to absorb specific non-visible wavelengths of sunlight.

A transparant layer over our windows which generates energy, is that possible? Yes!
A team of researchers at Michigan State University has developed a new type of solar concentrator that, if placed over a window creates solar energy while allowing people to actually see through the window.
