For dye sensitised solar cells follow this link to Wikipedia http://en.wikipedia.org/wiki/Dye-sensitized_solar_cell
Also known as Gratzel cells by the man who invensted them in 1991, their efficiency is steadily increasing, although I am not aware that they are being made avalable commercially yet. Some talk of military applications - tents that can recharge batter packs etc.

@ kiran

I was getting busy with experiments...so didnt chk.... neway... thanks for explanations.... and i think u might have heard abt nanofluid or thermal fluid which are used to reduced the thermal loss in thermal management system both at micro and nano scale.... i think reducing the work function and simultaneously using nanofluid to counteract the thermal effect.. can the efficiency be increased ?

Comment by Kiran Kumar V S on June 5, 2009 at 7:15am

@ Karthikeyan

1) Reducing the work function, will obviously give the photo electrons that extra energy to overcome the collision energy loss and reach the other end of the apparatus..i.e producing current.

Hence if work function is reduced, then the number of photo electrons contributing to the photo current will increase definitely if not considerably.

2) But keep in mind the energy is also lost by heating the material.

3) Reducing the work function is like reducing the effect of one of many factors affecting the efficiency of a solar cell.

Comment by N R Karthikeyan on June 5, 2009 at 6:27am

wow.... thats a wonderful explanation... thanks.... bt the point.. am i material engineer.... to my understanding... u mean to say if we can somehow tune down the energy requirement to eject photons..... probably the efficiency may get increase rite ?...

Comment by Kiran Kumar V S on June 5, 2009 at 6:13am

@ Karthikeyan

Solar Power Plants work on either Photoelectric effect i.e Photovoltaic cell or convert water into steam and then into electricity.

In photovoltaic cells Not all the solar energy is directly converted into power as some of the energy is used in ejecting photo electrons..and the energy used to eject photo electrons is property of the material used i.e work function of the material. Most of the photovoltaic cells are made of silicon which has a work function of 4.52 ev. Hence 4.52 ev amount of the energy is used to eject electrons itself and the rest is used by the electrons as kinetic energy, which generates current. But electrons tend to loose some of its kinetic energy by collisions. Hence the efficiency is very less.

When it comes to converting solar energy into steam, and then into electricity, it works like the steam engine of the olden days.....and you imagine the rest... ;-)

Hi everyone

What is the main reason for reduced efficiency in solar power plants ?
