Abstract
PV technology has direct correlation with the key parts from Semiconductor,
Material, Electric/Electronics, Construction, Engineering, and Chemical
Industry. PV technology has also close relationship with Display industry such
that it is necessary for securing abundant future energy as well as
transforming industry structure and has importance as continuous energy
business. Utilizing characteristics and application technology of solar
energy, a pollution-free energy source, it offers replacement from the
traditional energy dependence on fossil fuel and at the same time, resolve
environmental problems to lead humanity in having much more comfortable life.
In sum, PV technology is the future business combining 3E, Economic Growth,
Environment Protection and Energy Security.
Until the first half of 2008, PV industry went through rapid growth and each
country designated PV business as the "Engine for Next Generation Growth
Business" and aggressively promoted the industry. However, the global economic
recession began in the second half of 2008 and sharp price drop of module due
to the oversupply of polysilicon had facilitated PV industry to enter fierce
competition era that solar cell/module manufacturing makers were burdened with
product efficiency improvement and saving production cost for "Survival".
As the overall PV industry were given with the goal of innovative saving in
production cost, recently Dye-sensitized Solar Cell (DSSC) has emerged as the
3rd generation solar cell. Unlike traditional semiconductor solar cell that
utilize wafer substrate, Dye-sensitized solar cell became widely known as
Prof. Gratzel reported high-efficiency Photo-electrochemical solar cell basing
on the principle of Photosynthesis that showed 7.1% conversion efficiency to
the Nature in 1991. The conversion efficiency of DSSC was higher by using wide
band gap semiconductor, TiO2 (band gap: 3.2eV) that currently shows over 11%
energy conversion efficiency. Compared to other solar cell that utilize highly
expensive polysilicon and vacuum equipments, the production cost of DSSC could
be saved from 1/2 up to 1/5 of the production costs of other solar cell that
gathers much attention recently as many international companies announcing
their plans of commercialization. However, there exist merits of savings in
the manufacturing costs but commercialization had been delayed due to low
Photo-conversion efficiency of the module, reliability in long-hours and
problems in original patents.
Recently, companies that are developing DSSC offer data resolving problems in
reliability on long-hours one by one and as the original patent owned by Prof.
Gratzel from Swiss expired on Oct. 2008 that international companies centered
in Japan announced commercialized prototypes that anticipates earlier
commercialization of DSSC that expected.
