It's easy to think about modules as singular units of power output, but the reality is that they are a collection of diverse components, each with influence over the end system's total cost and performance. For DuPont, its focus is of course on the materials side, from metallization pastes used to form contacts on the solar cell, to backsheet materials that protect the panels themselves.

Miasolé says it has created a 17.3 percent "champion" thin-film copper-indium-gallium-selenide (CIGS) solar photovoltaic device, results obtained in its own labs and not (yet) independently verified.

Two reports out in the past week examine Europe's solar PV market in 2011, indicating slowing growth in the flagship countries and promise in some smaller regions for 2012 and beyond. Note that the data that follows is preliminary; final 2011 numbers won't be known until later in the first quarter, including some likely revisions thanks to a stronger-than-expected fourth quarter in several key regions (more on that below).

Concentrated photovoltaics (CPV) is an upcoming renewable market that promises to provide cost-effective power generation at high levels of efficiency. The performance of a CPV system is dependant on the direct normal irradiance (DNI). Because of this major performance parameter, the number of regions ideal for CPV system installations is limited. According to Prof. Humayun Mughal, the potential market destinations based on DNI for the CPV technology are Southwest US, Mexico, Chile, Southern Peru, Southwest Bolivia, Northwest Argentina, and Mediterranean countries, Australia, North Africa, Middle East, Western India and Western China.

The volatile swings seen in the upstream part of the solar PV supply chain, from silicon to cell/module pricing, have been well documented. End-market demand and associated policies supporting it is also a roller coaster, with many key regions currently embroiled in what to do for 2012 and beyond.

System-level monitoring, continued adoption of string inverters for large PV installs, and improvements by Chinese suppliers are among the trends gleaned from a survey of inverter buyers & sellers.

One dollar per watt: that's the mark the solar industry is hoping to hit in order to become cost-competitive with conventional energies. In a bid to reach this magic number in the next two years, various Asian manufacturers are striving to reduce costs by increasing volume production. An alternative direction that will benefit the industry in the long term is to target increased efficiencies primarily through new manufacturing processes, new higher-quality materials for metallization and changing the structure of the cell. Nanotechnology companies have developed these new materials and processes that enable manufacturers to both increase quality and lower-cost production, bringing the era of solar grid parity closer than ever before.

Asia-Pacific markets together added 2.8-gigawatts (GW) of solar PV installations in 4Q11 on the way to a total of 6GW for the entire year, an eye-popping 165% growth, thanks in large part to a massive run-up in China's domestic sector, according to calculations from Solarbuzz.

2011 was "a breakout year" for CIGS solar PV as suppliers continued to trim production costs, increase module conversion efficiencies, and widen adoption in commercial rooftops. But while CIGS (and thin-film brethren CdTe, thanks to First Solar's market leadership) continue to press on, the solar PV industry is still very much dominated by silicon, which has more standardized manufacturing on the one end and far more installed capacity on the installation side -- and all-important bankability thanks to both.

The U. of Buffalo (NY) says adding quantum dots into solar cells could increase their efficiency by a whopping 45%.

Europe may be the big end-market for solar PV demand (at least for now), but from a manufacturing standpoint Asian firms are beginning to dominate.

"Desperate" installers rushing to complete installations ahead of FiT reductions in key end-markets caused a 7% spike in PV module prices in December, but look for a return to familiar pricing pressure within just a month, according to IMS Research.
