The Evolution and Economics of Solar PV Cells

LONDON, Oct, 2014 -The Evolution and Economics of Solar PV Cells ( Solar Thermal Magazine).  Technology trends, economics, costs and prospects for solar photovoltaic power generation

By 2013 the aggregate global installed capacity was 136,700MW, and annual growth was 37,007MW, the highest annual growth yet recorded.
In 2013, the largest capacity addition, 11,300MW, was in China, followed by Europe with 10,253MW.

Chapter 1. Solar power, the solar resource and the growth of solar cells
Solar energy is the most abundant energy resource on the earth today, with the amount of energy reaching the surface equivalent to 7,500 times annual energy consumption. Solar cells are robust solid state devices that can operate under virtually all light conditions. Their output is greater the higher the light intensity available. Solar intensity varies globally, with the best regions generally close to the equator. Africa, south and southeast Asia, Australia, the southern states of the USA, and central and south America – all have good resources. However, even regions with lower average insolation, such as northern Europe or Japan – can exploit solar photovoltaic technology successfully. Solar cell capacity has grown rapidly in the second decade of the twenty-first century, reaching 137GW at the end of 2013.

Chapter 2. Solar cell technologies and technology trends
Solar cells rely on semiconductors to absorb light, and convert it into electricity. Each semiconductor is characterized by a bandwidth, and the optimum bandwidth for a solar collector is 1.4eV. The most popular material for solar cells is crystalline silicon, and the market is dominated by cells made from either single crystal or multicrystalline silicon (polycrystalline silicon) substrates. At its best silicon can achieve close to 25% energy conversion efficiency. Other materials, such as cadmium telluride or cadmium selenide are usually deployed in the form of thin films, which are conventionally considered cheaper to produce, although recent economic trends have contradicted this. Most solar devices are made from simple planar structures, designed to absorb light across their surface. An alternative approach is to use a very high efficiency, multilayer, solar cell and a solar concentrator. Concentrating solar converters have achieved nearly 45% efficiency in laboratory conditions. Organic solar cells are also being developed. These should also be cheap to produce if they can be perfected. While these new technologies are explored, conventional silicon cells have come to dominate the market with a share of 83%, and this dominance can be expected to continue over the short to medium term. Meanwhile, production is concentrated in China and Taiwan.

Chapter 3. The economics of solar cells
Solar cell costs have fallen rapidly over the past four to five years, and this has led to the technology becoming more competitive, in turn leading to cuts in subsidies for solar photovoltaic installations. With the cost and value of solar energy in flux, the US state of Minnesota has recently introduced a new, transparent approach to solar pricing that could for the benchmark for solar tariffs. The underlying capital cost of a solar PV installation depends in part on the type of installation – with small residential rooftop installations costing more than large utility installations. Costs also vary from country to country, with variations depending on a number of elements that are not intrinsically a part of the actual solar installation. In particular, the cost of rooftop installation in Germany is significantly lower than the same installation in the USA. It seems likely that installation costs are widely below US$3/W. The low cost of solar photovoltaic installations means that the cost of the electricity they produce has also fallen. For domestic rooftop installations, this cost is now below the cost of electricity from the grid in a number of important markets.

Chapter 4. Future market and economic prospects for solar cells
The market for solar cells has shifted away from Europe, the main driver for the past decade, towards Asia and the Asia Pacific region. However the market is also broadening and growth can be expected in many parts of the world – that have previously not shown a strong take up. This is being driven by the competitiveness of solar photovoltaic technology – which can now compete in some areas without any subsidies. This will come in spite of an expected stabilization of the cost of solar modules. On one prediction, the size of the solar market, globally, will reach 100GW by 2018. Over the longer term, estimates for the amount of electricity that might be supplied globally by solar cells varies between 0.6% and 4% by 2035. In Europe it already supplied 3% of total electricity demand. Important regional markets include China, Japan, the USA, Australia, and Mexico. The development of new financial vehicles that attract private sector investment for solar installations could help lower the cost of financing solar photovoltaic projects, potentially leading to further cost reductions.

Key findings of this report

By 2013 the aggregate global installed capacity was 136,700MW, and annual growth was 37,007MW, the highest annual growth yet recorded.
In 2013, the largest capacity addition, 11,300MW, was in China, followed by Europe with 10,253MW.
By far the largest US market was in California, with 2,621MW of solar PV added in 2013.
The largest share of the market in 2013 was taken by multicrystalline silicon cells (polycrystalline silicon), with 64% of the total, followed by conventional single crystal silicon (monocrystalline silicon) with 19%.
In March 2014, German modules were priced at €0.68/W and Japanese/Korean modules at €0.69/W. The continued price difference reflects a perception that Chinese modules are less robust and reliable than their competitors, but the margin is narrowing.
