The Problem with Silicon Wiring in Solar PV Cells
“How does silicon wiring harm solar PV Cells?”
Silicon wiring is needed for the electrons produced in solar PV cells to move around. However, the wires on the front of the solar cells cover 5-10% of the surface and reflect incoming light, thereby lowering the efficiency. As a result, there are many Problems with Silicon Wiring in Solar PV Cells.

Why Rooftop Solar Could be Greatly Beneficial for India
“How could India greatly benefit from rooftop solar initiatives?”
India’s urban population is massive. Totaling over 300 million people, It is nearly equal to that of the entire United States! This in turn will lead to a massive consumption of energy, which could result in further air pollution and carbon emissions. However, this can be challenged by implementing rooftop solar. This will result in locally generated, clean power that will bright up the cities. As a result, Rooftop Solar Could be Greatly Beneficial for India.
Why Solar Energy Makes Sense for Manufacturing
“Why does solar energy make sense for manufacturing?”
In honor of National Manufacturing Day here in the US, we here at Isaac’s Science Blog have decided to make a special report on how solar PV can be used in manufacturing.
Factories and manufacturing processes use most of their energy during the daytime. The energy costs and carbon emissions of this can be offset by using solar pv systems on roofs and on nearby arrays. This makes the manufacturing system not only much more efficient but also affordable. An example of this can be seen in the Tesla Gigawatt Factory’s solar roof. As a result, Solar Energy Makes Sense for Manufacturing.

“How can we charge appliances that are not solar-powered using solar power?”
Solar energy is one of the cleanest energy sources known to humanity. But not everything is solar powered. However, we can make a workaround using Solar Chargers, which directly convert solar energy into electricity that can be used by all sorts of appliances.

How Hurricane Florence will Test Solar Resilience
“How will Hurricane Florence serve as a test-case for solar resilience?”
Hurricane Florence is about to descend into the U.S State of North Carolina, which has the second highest amount of solar energy capacity in the nation. During this time we will be able to see firsthand how solar PV systems will respond to a hurricane and their level of resilience.

Phase Changing Materials for Solar Panels
“How can we use phase-changing materials to cool down solar panels?”
Solar PV is the fastest growing energy system in the world. But that doesn’t mean that it’s without its problems. When they become too hot, they become very inefficient and reject a lot of heat into nearby structures. One way to counter this is to attach a layer of Phase Changing Materials at the back of the panel. The phase-changing material is a material at its critical value so it can absorb a voluminous amount of latent heat without changing its temperature. Not only does it act as a passive heatsink but it can store this thermal energy to be used in other applications such as heating water. Phase changing materials are usually attached in a capsule behind the PV panel and have an air gap behind them to ensure cooling. This is a great example of Phase Changing Materials for Solar Panels.
How Building-Integrated PV Can Increase Climate Resiliency
“How do solar panels on buildings increase climate resiliency?”
With the advent of exacerbated global catastrophes, climate change resiliency must be built into all of our critical infrastructure systems. One facet is this is to reduce the reliance on long-distance transmission for electricity and carbon-intensive energy sources. One way to do this is to implement building-integrated solar PV. with BIPV systems, clean energy can be generated on site (allowing for off-grid power use even in the case of a blackout), and the need for transmission lines will be reduced (fewer transmission lines can reduce the potential for wildfires). In short, Building-Integrated PV Can Increase Climate Resiliency.
