Photovoltaics: is it time to forget about silicon?

Market overview: crystalline silicon has about 80% market share

But crystalline silicon approaches its efficiency limit

Now we have 23,2% efficiency

What is the limit of efficiency?

26% is the limit for crystalline silicon

5

ANY SUBSTITUTES?

6

MAY BE THIN FILM MODULES?

7

The answer is “no”

Why not?

Best thin film modules (CdTe, CIGS) have theoretical efficiency limit of 30%, now we have about 20,5% in best modules

High installation costs (a-Si)Deficit of raw materials (CdTe, CIGS)

Best thin film modules (CdTe, CIGS) are toxic

8

MAY BE ORGANIC MODULES?

9

NOT NOW

Why not now?

Organic photovoltaics is one of the most promising directions of developmentBut now technology is not well developed

10

CONCENTRATED PHOTOVOLTAIC MODULES IS GOOD SUBSTITUTE

FOR CRYSTALLINE SILICON

11

ADVANTAGES OF CPV

Why yes?

Theoretical efficiency limit is about 50%

Best modules have 32,5% efficiency. It`s more than theoretical limits for c-Si and thin film

Delivers 30% more energy than c-Si because of sun tracking

12

BUT CPV IS STILL EXPENSIVE

BECAUSE OF HIGH INSTALLATION COSTS

Because of sun tracker

Lifetime of CPV module is 20-25 years

But lifetime of CPV tracker is about 10 years

Tracker replacement increases total PV-system cost by 0,9 euro/W. This make CPV modules more expensive

THE GOAL IS TO DEVELOP NEW TYPES OF TRACKERS

WE WORK ON IT AT OUR R&D CENTER

OUR R&D Center

In 2011 we launched an R&D Center based on the territory of Physics and Technology Institute n. a. Ioffe., Saint-Petersburg, Russia

R&D Center offers: Access to research facilities and equipment;Knowledge sharing and joint research;Assistance in obtaining grant funding;Complete cycle development support.
