0 1 00:00:09,240 --> 00:00:10,680 Welcome to Soler energy course 1 2 00:00:10,690 --> 00:00:20,770 in the NewWay Academy We will be your lecturers for the coming 7 sections. 2 3 00:00:20,820 --> 00:00:30,030 This course is a general introduction into the variety of technologies which harvest the energy in solar light 3 4 00:00:31,670 --> 00:00:38,590 and convert it into electricity, heat or fuels 4 5 00:00:38,730 --> 00:00:44,450 In this first block, I would like to give you a short overview of the course. 5 6 00:00:44,710 --> 00:00:49,410 The course can be divided into three major part. 6 7 00:00:49,410 --> 00:00:52,180 The first part is section. 7 8 00:00:52,210 --> 00:01:02,130 One up to three which covers the fundamental physics principles on which the solar energy technology 8 9 00:01:02,550 --> 00:01:03,330 are based. 9 10 00:01:07,510 --> 00:01:17,020 The second part Section 4 and 5 discusses the solar energy technologies the third part 10 11 00:01:17,070 --> 00:01:27,770 The third part and the last part Section 6 and 7 discuss solar energy systems. 11 12 00:01:28,110 --> 00:01:35,060 At the end you are expected to be able to design your own solar system. 12 13 00:01:37,800 --> 00:01:45,610 the lectures are given in short videos around 10 minutes like this one. 13 14 00:01:46,920 --> 00:01:51,390 Between all videos you will find many exercises. 14 15 00:01:51,420 --> 00:02:00,950 In addition we have included more generic question which can act as discussion material for the students 15 16 00:02:01,350 --> 00:02:12,130 on the course blog we encourage you to participate in this life discussion my experience is that we 16 17 00:02:12,130 --> 00:02:14,140 can learn a lot from each other. 17 18 00:02:15,360 --> 00:02:23,640 Last course we had some great interaction between the student on the firms (Q&A). 18 19 00:02:24,310 --> 00:02:32,740 Later in the course you will have the opportunity to share the solar energy technology from your home 19 20 00:02:33,010 --> 00:02:36,470 neighborhood or city through picture. 20 21 00:02:36,760 --> 00:02:39,010 Self-made YouTube video 21 22 00:02:42,020 --> 00:02:45,190 at the end of each three parts. 22 23 00:02:45,380 --> 00:02:54,930 We will have a short exam which should cover the material discussed in the part of this course this 23 24 00:02:54,950 --> 00:03:08,310 mean you can do an exam at the end of section 3, 5 and 7 supplementary to the lectures exercise assignment 24 25 00:03:08,640 --> 00:03:19,020 and exams we offer you our new educational research for the photovoltaic material and devices group 25 26 00:03:19,200 --> 00:03:20,490 at the NewWay academy 26 27 00:03:20,500 --> 00:03:27,810 Academy entitled solar energy fundamental technology and system. 27 28 00:03:27,810 --> 00:03:34,290 Now I will give a more detailed overview of this course content for each section 28 29 00:03:38,610 --> 00:03:44,220 in Section 1 I will give you a general introduction into solar energy. 29 30 00:03:44,850 --> 00:03:49,380 I will discuss the variety technology for energy conversion. 30 31 00:03:49,440 --> 00:04:00,090 We are using today for our energy needs I will try to put the rule of solar energy in prospective in 31 32 00:04:00,090 --> 00:04:03,990 reference to other energy sources. 32 33 00:04:04,050 --> 00:04:13,140 I will teach you the difference between photovoltaic and solar heat you will be introduced to the concept 33 34 00:04:13,200 --> 00:04:23,400 of photovoltaics and its related technologies the current status and prospect of solar energy will be 34 35 00:04:23,400 --> 00:04:24,710 discussed as well 35 36 00:04:28,460 --> 00:04:33,290 in Section 2 is the most fundamental section of that course. 36 37 00:04:33,590 --> 00:04:42,920 I will introduce you to semiconductor physics and How we use semiconductor material in devices 37 38 00:04:43,400 --> 00:04:47,720 to that it converts solar light into electricity. 38 39 00:04:47,720 --> 00:04:51,440 Don't be afraid if physics is into your thing. 39 40 00:04:51,560 --> 00:05:02,170 I am using many animations to explain that physics principle of semiconductor material and photovoltaic 40 41 00:05:02,170 --> 00:05:10,350 devices in section 3 where we will discuss how we determine the performance of solar cells using the 41 42 00:05:10,350 --> 00:05:14,110 external parameter like open circuit voltage. 42 43 00:05:14,250 --> 00:05:20,880 Short circuit Caron then factor maximum power point and efficiency. 43 44 00:05:20,900 --> 00:05:29,170 In addition I will discuss the decision that I'll design the rules for solar cell the basics you learn 44 45 00:05:29,250 --> 00:05:39,580 in the first three sections forms an excellent tool box to understand the various solar technologies 45 46 00:05:39,880 --> 00:05:50,440 and solar systems we introduce in the last the four sections note that that section 3 has the highest 46 47 00:05:50,440 --> 00:05:51,120 workload. 47 48 00:05:51,400 --> 00:05:57,120 So please divide your time wisely after Section 3. 48 49 00:05:57,170 --> 00:06:06,410 You will have your first small exam based on part 1 in Section 4. 49 50 00:06:06,470 --> 00:06:16,720 We will discuss the most dominant solar cell technology which is based on silicon crystalline wafer. 50 51 00:06:16,730 --> 00:06:25,430 We will discuss that processing methods the various different device concepts and the challenges of 51 52 00:06:25,430 --> 00:06:34,160 silicon crystalline PV technology for the future and we will discuss the other PV technologies based 52 53 00:06:34,190 --> 00:06:43,930 on thin films. thin films PV technology use less material and it's produced by cheaper processing 53 54 00:06:44,260 --> 00:06:49,780 methods to further reduce the cost price of solar energy 54 55 00:06:52,940 --> 00:06:58,360 in Section 5 we will start to discuss the PV system. 55 56 00:06:58,400 --> 00:07:06,560 We will introduce you to other component of PV such as batteries, Inverters and maximum 56 57 00:07:06,560 --> 00:07:14,110 power point tracker and charger controller in section 6 57 58 00:07:17,220 --> 00:07:25,230 we will discuss the most popular system technology like off grid and on grid system 58 59 00:07:29,330 --> 00:07:31,230 in Section 7. 59 60 00:07:31,280 --> 00:07:42,810 We will provide you the tools to be able to design any PV system on paper for any application after section 60 61 00:07:42,810 --> 00:07:43,870 7. 61 62 00:07:43,920 --> 00:07:55,670 You will have your last exam one of the most beautiful aspects of this course is that solar energy is 62 63 00:07:55,670 --> 00:08:05,170 interesting for many people from different study to come and learn about it. also so this course is aimed 63 64 00:08:05,260 --> 00:08:08,000 at bachelor level students. 64 65 00:08:08,260 --> 00:08:16,960 Anybody with a good grasp of high school physics and mathematics and especially an open mind can not 65 66 00:08:16,990 --> 00:08:26,350 only understand but enjoys this course experience only a very few exercises or assignments. 66 67 00:08:26,350 --> 00:08:36,520 Question requires a basic calculus but don't worry if you are into skilled in calculus you are still 67 68 00:08:36,640 --> 00:08:40,330 able to successfully completes this course. 68 69 00:08:40,330 --> 00:08:48,370 In addition I realize that people with the various background participate in this course successfully 69 70 00:08:51,180 --> 00:09:01,740 so in the first section we will start with exercise to make people familiar with typically unit used 70 71 00:09:01,770 --> 00:09:03,430 during this course. 71 72 00:09:03,480 --> 00:09:09,450 So as the course has been designed to take you through the various aspects of solar energy discussed 72 73 00:09:09,990 --> 00:09:19,980 before over the 7 sections in general the way the exercises will increase your comfort level was using 73 74 00:09:20,220 --> 00:09:24,410 the basic math to understand solar energy better. 74 75 00:09:25,470 --> 00:09:36,020 so after the introduction let's get the start so that energy technology is based on conversion of 75 76 00:09:36,020 --> 00:09:42,390 the energy of light into electricity heat and solar feul. 76 77 00:09:44,080 --> 00:09:50,720 It means we are going to talk about energy conversion. 77 78 00:09:50,760 --> 00:09:55,890 We will discuss that in great detail in the next block. 78 79 00:09:56,460 --> 00:09:59,520 So see you in the next block.
