Solar Panel Cost Competitiveness

In 2010, the average cost per DC Watt of solar photovoltaics on a utility-scale installation was around $4.57 USD. By 2015, this number dropped down to $1.82 USD. By 2020, this number has dropped to around the $1.00 USD mark... Read More

Carbon Tax

Governments around the world have been implementing various policy tools to reduce greenhouse gas emissions. One of the most popular tools is a carbon tax. What is a Carbon Tax? A carbon tax is aimed at reducing human generated CO2... Read More

Cap and Trade

Many people consider a cap and trade system to be the most palatable option when it comes to reducing pollution and greenhouse gas emissions. Major economies such as the United States, European Union, Canada, Australia, and Japan have all implemented... Read More

Decarbonizing our Energy Infrastructure

Growth of renewable energy is happening slowly, and it will be decades before renewables can carry the majority of the electricity load. In the meantime, we need to keep global temperature rises in check with the tools at our disposal.... Read More

LCOE Formula

The levelized cost of electricity (LCOE) is the key method through which we compare economic viability between renewable energy and fossil fuel power generation. In its most basic form, the LCOE formula is: This form of the LCOE formula isn’t... Read More

Levelized Cost of Electricity

The levelized cost of electricity (LCOE) is fundamentally a break-even sales price (in dollars per kWh) needed to justify an investment in a particular power generation facility. It is the primary measure used to compare the cost-effectiveness of different electricity... Read More

Cadmium Telluride Solar Cells

Cadmium Telluride (CdTe) is the material of choice for making thin film solar cells. Thin film solar cells are only 1/10 the thickness of a human hair, and this allows the cells to be lightweight and flexible. One advantage of... Read More

Perovskite Solar Cells

What is a “perovskite”? It is essentially a salt with a lot of desirable properties for making a solar cell. Some of these impressive properties include: A tunable energy band gap A high absorption coefficient Ability to be printed A... Read More

Gallium Arsenide Solar Cells

Today, we are taking a look at one of the highest performing solar cell materials available – Gallium Arsenide. Gallium Arsenide (GaAs) is a combination of the elements gallium and arsenic. It is used in the manufacturing of common items... Read More

Silicon Solar Cells

There are many different materials and methodologies to constructing solar cells. Today, we are taking a look at the current market leader – silicon solar cells. Silicon is used everywhere in our world. Applications include steel refining, chemical industries, and... Read More
