Examples

The first example is adapted from a paper that required a lot of revision and included some sentences whose meaning was unclear, particularly at the start. Here is the uncorrected text.

As a clean and renewable energy, solar energy has been burgeoning advanced in the past several decades. Which already became the fastest growing industry for new investments and solar PV systems have increased by 44%. The global annual PV installation is nearly 40 GW and evolution of PV installations growth to 177 GW in 2014. Bulk silicon solar cell (multi-crystalline and mono-crystalline) mastered the major market due to its high efficiency and mature technology. However, the high cost of silicon wafer reduces their cost-competitive, while the thinner thickness of silicon wafer can obviously reduce the cost.

  In recent years, silicon nanowire (SiNW) solar cells offer a potential advantage to replace the bulk crystal silicon solar cells. Because of some enormous advantages, radial junctions to obtain shorter carrier collection path, light trapping effect by nanowire arrays to enhance absorption and thinner thickness led to particularly low cost of silicon wafer. Despite such advantages of SiNW solar cells, the industrialization is still in the early stage. Especially relatively lower efficiency compared with bulk silicon solar cells is a major problem, which many come from many recombinations of generated charge carriers due to high surface defects and interface areas of SiNW arrays. To improve the performance, some alternative methods need to investigate.

I also made some comments in the margin (not visible above). For example, in the second sentence, it is necessary to clarify when the number of systems increased by 44% (‘in the last 5 years’ was given as a possible example). Also, on the third line from the bottom, should ‘many recombinations of’ be recombinations of many’? Parts where the customer needs to check particularly carefully that the intended meaning has been retained were also pointed out.

Suggested changes can be easily accepted or ignored (see tutorial here). Here is the final text.

As a clean and renewable energy, solar energy has been rapidly adopted in the past few decades. It has become the fastest growing industry for new investments and the number of solar PV systems has increased by 44% in the last 5 years. In 2014, newly installed PV systems generated a power of nearly 40 GW, increasing the total power generated worldwide by PV systems to 177 GW. Multicrystalline and monocrystalline bulk silicon solar cells dominate the market owing to their high efficiency and mature technology. However, the high cost of silicon wafers reduces their cost-competitiveness, although reducing their thickness can lower their cost.

Silicon nanowire (SiNW) solar cells potentially have major advantages as replacements of bulk crystal silicon solar cells. These include radial junctions to obtain a shorter carrier collection path, a light-trapping effect of nanowire arrays to enhance absorption, and reduced thickness, greatly lowering their cost compared with that of silicon wafers. Despite such advantages of SiNW solar cells, their industrial production is still in the early stages. Moreover, their relatively low efficiency compared with that of bulk silicon solar cells is a major problem, which may originate from the recombination of generated charge carriers due to the high density of surface defects and the large interface areas of SiNW arrays. To improve their performance, various approaches need to be investigated.

The second example is part of a paper for which the basic proofreading service was required.

Here is the original text. You may wish to try to find the 12 errors before seeing the corrected version below!

Si has been used as semiconductor materials for electronic devices such as CMSO devices and large-scale integrated circuit (LSI) for a long time. Recently it has attracted increasing attention for applications to biocompatible devices such as drug delivery devices and biosensors using micro electro mechanical systems (MEMS) and photonic integrated circuits (PICs) for optimal connection, which is known as silicon photonics. For realization of the devices and ICS, fine, uniform and highly adhesive metal patterns for electric wiring or electrodes is essential
As processes for metal pattering on Si, photolithography process and damascene proess are usually used. However, this processes are very complicated because they include dry etching of metals and chemical mechanical processing (CMP), respectively. In addition, large-area uniformed metal deposition requires large vacuum evaporation or sputtering equipment.

All the corrections are straightforward and no changes have been made to the style. Note that three typos that would not be picked up by a spellchecker (CMSO, pattering, and uniformed) have been corrected.
