In the long run, renewable energy will be the main energy source of future human, so most of the developed countries and some developing countries in the world have attached great importance to the important role of renewable energy for the future energy supply. In the new renewable energy, photovoltaic and wind power is one of the fastest growing, all countries in the world commercial development and utilization of solar energy photovoltaic power generation as a important development direction. By 2030 solar power will show its important role in the supply of electricity in the world, more than 10%, renewable energy accounted for 30% in total energy structure; Solar power 2050 will account for 20% of the total energy consumption, renewable energy accounted for more than 50%, by the end of the century solar power will play a leading role in the energy structure.

Here also give what is CIGS cells, from the above you can see, solar cells, according to different materials have different classification according to the application level of photovoltaic (pv) can sort of polycrystalline silicon single crystal silicon battery CdTe CIGS amorphous silicon battery and other solar cells. Overall, CIGS cells is a kind of solar cell, just the battery cell material USES the copper indium gallium selenide (cadmium - indium gallium selenide - CIGS) material, thus forming the p-n junction of solar energy to absorb light and electricity, the material of the solar cell with low cost, high conversion efficiency and gain recognition in the market, and in all the share of the solar cells is increasing. Also the investment hot spots in current solar cells.

At the current technical development forecast, high conversion rate of crystalline silicon cells, thin film cells, as well as the high concentrated multi-junction cells will be the developing trend of crystalline silicon cells, amorphous silicon thin-film batteries both technical route the most optimistic prospect. In large power plant construction, conversion efficiency is still has the potential to improve the high concentrated multi-junction cells provides an efficient and environmentally friendly solutions; At the same time, the competitiveness of CPV in grid-connected power generation cannot be ignored, in addition to the cost is low, the technical route can complement each other and biomass, natural gas power generation, and achieve continuous stable power supply). In addition, photovoltaic and thermal hybrid power generation and scenery complementary, and other forms of hybrid power generation, because can make up for solar power caused by solar radiation, the weather changes with time of the output power unstable faults, is the better choice grid-connected power generation system.

In order to meet the needs of everyone of timbre, and design the product modularization, similar to the SLR, the user can change the lens, the fuselage, and we went a step further, the system is divided into the nose, DAC, ear, completely independent, like listening to classical or vocal burn friends will have the freedom and tie-in combination

Adopts the modular design is the core of our design concept, DAC and replaceable, amp can continue to upgrade products, a good design ensures backward compatibility, can meet most of the DAC chip on market. Put the module has plenty of PCB area, do not hesitate to increase the thickness of the fuselage reserve the position of the electrolytic capacitor. The future will have to upgrade balance board, and carry the potential of gold seal op-amp, even, you can also join the developer, do their own DAC and the ear plate.

What kind of machine is burn friend's dream? High voltage power supply, the god of the op-amp, DAC, acura capacitance, slender figure, had better be a hand can grasp. In portable confidential to achieve such a request, however, the hard, final system as the top use R - 2 R DAC PCM1704, can upgrade replacement modules, native double power supply so the combination of the dream.

Note the "native" 2 words, here is the battery can be divided into two groups, a group of a set of positive voltage negative voltage, without any conversion, the disadvantage is that the cost is very high, the laptop machine is very rare in this way, benefit is the audio part don't need coupling capacitance, do pure dc amplifier, power supply part without any conversion noise, our power supply voltage of 16.8 V, 8.4 V in the two groups.

Finally, we built three stories in small machines, respectively is the mainboard, DAC, ear, (editor's note: this is the reason why the fuselage thick) with 4 pieces of single section 1150 ma of lithium battery, can promote the headphones small player finally was born, it is the MA9.
