These layers have different bandgaps, allowing a broader range of light wavelengths to be converted to electricity.<\/p>\n<p>Assuming success, technology developed under the $4 million R&amp;D project could be integrated into current solar manufacturing with minimal production changes.<\/p>\n<p>Professor Martin Green, founder of ACAP at the University of New South Wales and often referred to as a &#8220;father of solar&#8221;, was also the founder of the Solar Photovoltaics Group at UNSW in 1974. He was one of the lead inventors of PERC (passivated emitter and rear contact\/cell) technology in 1983. PERC is utilised in many solar panels available today and was (is?) the dominant technology. While TOPCon (Tunnel Oxide Passivated Contact) appears to be taking over from PERC, IBC has potential to displace TOPCon as the most common tech.<\/p>\n<p>Commenting on the partnership, <a href=\"https:\/\/www.acap.org.au\/post\/aiko-solar-signs-partnership-with-acap\">Professor Green said<\/a>:<\/p>\n<blockquote><p>\u201cWith UNSW\u2019s world-class research capabilities and AIKO\u2019s industry leadership, we aim to push the boundaries of photovoltaic performance and shape the future of solar energy.\u201d<\/p><\/blockquote>\n<p>ACAP was founded in 2013 and is funded by the Australian Renewable Energy Agency (ARENA), university and industry partners. In July this year, ACAP&#8217;s Industry Consortium initiative kicked off with founding industry partners including Aiko.<\/p>\n<blockquote><p>\u201cThe ACAP Consortium serves as the foundation for this partnership, bringing together leading academic institutions and industry partners to foster innovation and drive the development of high-efficiency solar technologies,&#8221; said executive director of ACAP, Professor Renate Egan.<\/p><\/blockquote>\n<h2>As Easy As ABC\/IBC<\/h2>\n<p>Aiko&#8217;s ABC (All Back Contact) technology, aka IBC, involves having all electrical contacts on the rear side of the solar cell. The positive and negative contacts are arranged in an interlocking pattern; making it easier for electrons to flow efficiently. The absence of metal ribbons on the front reduces shading.<\/p>\n<p>Furthermore, <a href=\"https:\/\/aikosolar.com\/en\/products\/all-back-contact-cell\/\">AIKO&#8217;s ABC tech<\/a> doesn&#8217;t use costly <a href=\"https:\/\/www.solarquotes.com.au\/blog\/solar-silver-cost-mb2939\/\">silver<\/a> but much cheaper and more abundant copper instead to bond with the silicon. This, Aiko says, also enhances cell mechanical strength and flexibility &#8211; reducing the risk of microcracks developing that can impact power production and module service life.<\/p>\n<p>ABC\/IBC tech can also be combined with materials other than silicon such as <a href=\"https:\/\/www.solarquotes.com.au\/blog\/perovskite-solar-panels-mb2953\/\">perovskite<\/a> for tandem cells.<\/p>\n<h2>Aiko Making Its Mark In Australia<\/h2>\n<p><a href=\"https:\/\/www.solarquotes.com.au\/panels\/aiko-solar-review.html\">Aiko Solar<\/a> has only been on the Australian home solar scene since March this year, but is already turning heads.
