Which man who improved solar panels and lives in california? Solar energy has formed one of the basic pillars underlying the process of a revolution in renewable energy. Particularly, the case is so in the sunny state of California. With an increasing quest for cleaner energy sources, there is a continuous rise in the need for more efficient solar technologies. Among the many innovators stretching what these silicon wafers are capable of, Dr. Martin Green is a larger-than-life working example at the epicenter of the solar industry in California.
While the majority of his work is in Australia, with the various dynamics he adds to the development of solar technology, his contributions have really helped in placing California well ahead of the rest in using solar energy. The article talks about a man who improved solar panels and lives in California and breakthrough work in increasing solar panel efficiency, the effect of his innovation in California, and what it holds for the future of solar power.
Dr. Martin Green: The Man Behind the Innovation
Dr. Martin Green is known globally as one of the greatest masters of photovoltaic technology. Having been born in Australia, Green spent his entire life working on methods to reduce the cost of solar panels further and improve their efficiency.
His work has been recognized worldwide and has been the recipient of many awards, including the highly prestigious Global Energy Prize. Over the past decades, Dr. Green and his team have set multiple world records for the efficiency of solar cells while working at UNSW, making large strides in renewable energy.
Arguably, the most relevant of Dr. Green’s many accomplishments is the development of Passivated Emitter and Rear Cell (PERC) technology, now a new industrial standard. In simple terms, the PERC technology allows solar cells to get a grip on more sunlight to convert into electricity much better than a traditional solar cell.
With this invention, the performances of solar panels were increased, and it dropped the cost per watt of solar power, which consequently made the product affordable to consumers all around the world.
How PERC Technology Works
Perhaps an understanding of his work would rely initially on knowing how PERC technology works. Most solar companies manufacture conventional solar cells designed to capture the sunlight at the front surface and convert its energy to electricity. However, a fraction of it bounces without being absorbed by the cell, hence a loss of energy. PERC technology introduces a reflective layer on the rear surface of the solar cell. Through this layer, the bounced sunlight is given another chance to get back to the cell and be reabsorbed, this time into electricity.
This seemingly simple but very effective modification ushered in radical improvements in solar panel efficiency. PERC solar cells can touch efficiencies of as high as 23%, while the efficiencies in conventional solar cells go up to 15-18%. Such high efficiency is very significant as it relates more efficiency to more generation for a similar amount of sunlight. This surge in potential production has made PERC panels something of interest to many homeowners across California for both residential and commercial solar installations.
Impact on California’s Solar Industry
Long before California primed itself to claim top spots for solar energy deployment around the world through its leadership in bright sunshine, farsighted energy policies, and strict commitments to lowering greenhouse gases, the state is at the forefront of promoting solar power, so much so that millions of homes and businesses are powered by solar. This is due, in no small part, to the successful commercialization of Dr. Green’s research.
This means that as the introduction of this technology enables more efficient and cost-effective production in the first place, PERC technology drives down the cost of solar installations even lower.
Therefore, homeowners and business establishments from across more parts of California now afford the investment required in the installation of solar energy, greatly furthering the state toward achieving the ambitious targets on renewable energy sources.
Solar Power Policies in California
The commitment in California to the use of renewable energy is seen in the state’s energy policies, which were previously supportive of the implementation of other solar technology forms. For its residential and commercial customers, the California Solar Initiative offered ample incentives that were considered effective for its inception in 2007. Though the CSI initiative has long expired, it was in so many ways a cornerstone of California’s solar boom.
In 2020, California introduced such a landmark mandate for all new residential buildings: they must come with solar panels. It was actually the first mandate in the United States ever, and once more, with this leadership, California goes further for solar energy. With mandates for very high-efficiency solar panels present in the market, innovations like PERC technology become even more valuable due to the mandate, thereby driving bigger demand.
Wider Societal Implications of Solar Innovations
It has paid dividends not only to Californians but to the world. Innovations making solar cells more efficient and lower in cost like PERC only gain in importance as the world grapples with climate change and the need to transition to renewable sources of energy. With progress in making solar panels more efficient but cheaper, Dr. Green indeed contributed to the massive stride the solar photovoltaic market made.
Alongside PERC technology, Dr. Green has continually pushed the envelope in solar innovation. He has researched new materials and techniques for increasing the efficiency of solar cells, including tandem solar cells at the heart of the research laying various types of cells one above the other to harness a larger spectrum of sunlight. This, therefore, opens future avenues toward more efficient and cost-effective solar panels.
Challenges and Future Prospects
Despite the big strides so far made, challenges still persist. One of the most significant challenges is that it’s not being fully developed so as to drive solar efficiency to the limits. Even though the high efficiency represents a major step change for technology in PERC, there is clearly room for improvement. Now, researchers are looking towards new materials like perovskite that might offer even higher efficiencies at even lower costs.
Conclusion
The contribution of Dr. Martin Green in the field of solar technology, therefore, presents one of the world’s events, with global solar industries, California being the major beneficiary. His invention of PERC technology has further made solar panels more efficient and affordable, making them ride high in penetration of solar energy in California and the world at large. The future of energy generation will depend on more than ever innovations such as those pioneered by Dr. Green as California continues to set the example in renewable energies.

FAQs
What is the PERC technology in solar panels?
PERC technology is a Passivated Emitter and Rear Contact, which has greatly changed the increase in the efficiencies of solar panels. A reflective layer is added on the back of the solar cell with the aim of reflecting back the unabsorbed sunlight back to the cell, where it is converted into electricity; this thus increases the general efficiency of the panel.
What effects has PERC technology had on California’s solar industry?
That has shot up the efficiency of the solar panels in California by a great deal. Energy is produced so much from a small proportion of sunlight, hence making it easier and quite affordable for the homeowners and any other business to access solar energy, among many other attributes that put this state on top in the renewable energy revolution.
