Pasi Kautonen, Marketing Manager at Valoe Oyj, tells PES about the background and aspirations of this high-tech company. Their focus is on the developing high efficiency solar photovoltaic modules and automated module manufacturing technology. The company, originally named Cencorp, was founded in 1978. It soon acquired a reputation for innovative automatic robotic solutions for a wide range of industries. By the turn of the century, as a major global supplier of special components mainly for mobile phone industry, the company obtained advanced production and nano material experience in high efficiency laser technology and flexible back contact electrical circuits used for example in antennas inside mobile phones. By the end of the first decade of the millennium, Valoe moved its future business focus towards the upcoming and growing solar power industry. Through mergers and acquisitions backed by its own know-how of back contact technology Valoe started to implement its strategy to develop more sustainable, yet world leading, high efficiency solar modules and production technology. The company first started to develop and manufacture advanced back contact modules in Finland, which were based on polysilicon and monosilicon solar cells while also concentrating on enhancing automated production technology. In 2018 they launched their advanced and

Using electricity and heat generated by the same installation is an effective way to increase efficiency in buildings — and also cut costs. In co-generation systems, the fuel, in this case gas, is used to generate electricity using a small gas turbine and the waste heat is used to heat the building and provide hot water. Wirral Metropolitan College, near Liverpool, is setting a good example in this field. The college has four campuses located around Birkenhead in the Wirral. By the end of the year, it will be using gas to cover most of its Twelve Quays campuses own day-to-day heat and electricity needs. Reducing dependence on electricity prices The sharp increases in electricity and gas prices, in the UK in recent years, make this transition a worthwhile investment for the college. ‘This is a demonstration project which is receiving funding from the local authorities as part of an extremely low energy agenda,’ says George Norrie, Technical Director at Scotia Energy, the project designers and integrators. Wirral Metropolitan College is the first public institution to benefit from a multi-million regeneration programme for the town of Birkenhead, just across the Mersey from Liverpool. Its new Wirral Waters campus is the first building completed

Amid yet more uncertainty in the solar industry – fuelled by the recent policy shakeup in China and subsequent plunge in PV module prices – leading manufacturers know that the best course of action is taken with a steady hand and eyes fixed firmly on the horizon; a horizon shaped by PV innovation and quality. Right around the time that the world’s largest solar power exhibition, the SNEC show in Shanghai, was winding down at the end of May, Chinese officials were silently preparing to drop a bombshell that was soon sending shockwaves throughout the PV world. The country’s National Energy Administration (NEA), the National Development and Reform Commission (NDRC) and the Ministry of Finance had prepared a new policy that stated, in no uncertain terms, that the government would not approve any more subsidized large-scale PV projects for the remainder of the year, effective June 1. The government bodies also confirmed a cut in the feed-in tariff (FIT), placed a cumulative annual cap on distributed generation (DG) installations at 10 GW (previously 19 GW) for the year, and introduced a new auction mandate for utility-scale projects. There was a lot to unwrap in this new policy. The kneejerk response among many solar

Bertrand Lempkowicz, PR, Marketing & Communication Manager, at PV CYCLE, popped in to PES to discuss the importance of recycling and managing waste produced by so called ‘green energy’. Our industry should definitely make this an even higher priority. PES: Welcome back to PES Solar/PV magazine, it’s great to talk with you again. For the benefit of our new readers would you like to begin by explaining a little about the background of PV CYCLE and the importance of the solar/PV industry to you? Bertrand Lempkowicz: PV CYCLE was built on a voluntary basis, during the very first years of the photovoltaic Industry. At the very beginning, manufacturers were proud to be able to offer alternative renewable energy to fossil and nuclear energy and with good reason, but as for all types of energy, the end of life of the equipment must be taken into consideration. PV CYCLE was founded with PV modules in mind, by and for the photovoltaic Industry, which will now a few years later, can propose solutions for efficient recycling built on the experience gained from the first returns of broken, defective or end-of-life panels. On the other hand, when Europe introduced the photovoltaic panels into the WEEE directive,

There have been solar cells based on semiconductor technology since the middle of the 20th century, and photovoltaics (PV) have undergone continuous development since that time. Trends have always played a decisive role in the development of PV. An important trend is characterised by technology, market, materials and investors coming together at an opportune moment. Megatrends are indicative of especially strong changes that have a major impact on the development of technology and the market. Developments in photovoltaics Bell Labs made the first n-type silicon solar cell to generate electrical energy directly from sunlight as long ago as 1954. At that time, the semiconductor industry was in the very early stages of its development and material prices were still very high. After 1970, the semiconductor industry evolved rapidly, as a result of which suitable semiconductors became available. The first commercial solar cells were produced mainly using scrap wafers originating from the manufacture of integrated circuits. At the same time, research efforts were initiated with the goal of improving solar cell efficiency. The solar cell structures in use today were devised and first developed in the laboratory in a relatively short period of time. In some cases, however, it would take more than
