I have always been a follower of Elon Musk as someone with outstanding visionary thoughts whilst I do not approve of what he has done to Twitter. It proves you cannot get everything right. But in terms of his Solar Technology vision he has hit the spot in appreciating its significance as a technology of the future including our survival on Earth.
I have always had my own simplistic view on the subject. Using
the sun to power our civilisation rather than oil and gas, fossil fuels, makes absolute
sense particularly in the light of global warming. Seeing my conservatory heat
up from 10C to 38C in 30 minutes under direct sunlight under the effect of
photons never ceases to remind me of the power of the sun’s radiation. I view
the Sun as a very safe nuclear facility sited 93 million miles away rather
sited on my doorstep not posing any of the risks associated with land based
nuclear reactors.
We are so lucky that the laws of physics support the fact
that when a photon strikes a semiconductor an electron is released. The
electron being the fundamental particle that is electricity. This being the
principle behind a solar panel. Sort out the storage of electricity for when
the sun does not shine and powering our civilisation is simple and safe. Elon
Musk has built his empire based upon this simple approach to the powering of
civilisation significantly including the use of solely electrically driven
vehicles. Siting these solar panels in earth-based locations receiving maximum
sunlight or in space then the distribution of this generated electricity then
becomes the key task. So solar towers or arrays in deserts feeding smart AI
driven grid networks conserving and distributing the electricity generated. Or
space based mirrors projecting the photons down to specific terrestrial based
locations.
It does not take much imagination to appreciate that concentrating the photons to kick out more electrons making the electricity is going to become a key development strategy for solar panels. Being an electronics industry development pathway its easy to appreciate its effectiveness is going to multiply many fold similar to the way the so called Moores Law that has been applied to microprocessor development. The subject of Solar Technology has its own Physics Category called photovoltaics. Just to warn you photovoltaics has been abbreviated to PV in the industry.
So what does the ChatGPT have to say about photovoltaics
using its LLM.
Photovoltaics (PV) is a method for generating electrical
power by converting sunlight directly into electricity using semiconducting
materials that exhibit the photovoltaic effect. Here’s a brief overview:
Key Concepts
1. Photovoltaic Effect: The process by which a material
generates an electric current when exposed to sunlight. This effect was first
observed by Alexandre-Edmond Becquerel in 1839.
2. Solar Cells: The basic unit of a PV system. Solar cells
are made of semiconductor materials, typically silicon. When sunlight hits the
cell, it excites electrons, creating an electric current.
3. PV Modules and Arrays: Individual solar cells are
interconnected to form a solar panel (module). Multiple panels can be arranged
to form a solar array, which can generate more electricity.
4. Types of PV Technologies:
Monocrystalline Silicon: Made from a single crystal
structure. Known for high efficiency and longevity.
Polycrystalline Silicon: Made from multiple crystal
structures. Generally less efficient but cheaper to produce.
Thin-Film Solar Cells: Made by depositing one or more thin
layers of photovoltaic material on a substrate. They are flexible and can be
used in various applications, though they typically have lower efficiency.
5. Efficiency: The ratio of the electrical output of a
solar cell to the incident energy in the form of sunlight. Efficiency is a
critical parameter in the performance of solar cells.
6. Applications: PV systems are used in various
applications, from small-scale (e.g., calculators, watches) to large-scale
(e.g., solar farms, rooftop installations).
Advantages of Photovoltaics
Renewable Energy Source: Sunlight is abundant and free.
Low Operating Costs: Once installed, PV systems require
minimal maintenance and no fuel.
Environmentally Friendly: PV systems produce no emissions
during operation.
Challenges
Initial Cost: The upfront cost of PV systems can be high,
although prices have been decreasing.
Intermittency: Solar power generation is dependent on
sunlight availability, which varies with weather and time of day.
Energy Storage: Efficient storage solutions are necessary
to provide a continuous power supply when sunlight is not available.
Future Prospects
Advancements in materials science, manufacturing processes,
and energy storage technologies are expected to further improve the efficiency,
cost-effectiveness, and deployment of photovoltaic systems, making solar energy
a key component of the global renewable energy landscape.
So ChatGPT didn’t mention nanotechnology nor artificial
photosynthesis which is going to play a significant role in the future of Solar
Energy.
So do I have all this Solar Technology installed. The
answer is no. But this is purely me not being able to justify it as a capital
investment at my age. (76 years old). But my mates have it installed with their
electric cars running on sunlight. Down at the local public house they use
their Smartphones to show me what’s being generated, stored or returned to the
national grid. I try to book these days out with them on wet cloudy days so
they have less to impress me with in terms of their energy savings.
But I have invested in a garden solar light. I can but just
marvel at the solar panel, battery storage, switch to activate when darkness
falls and the LED bulb all costing just a few pounds. All this technology mass
produced in China for virtually nothing. It just needs enhancing to cater for
my domestic and vehicular energy needs at a similar price.
